YozzaSport Announces Scalable Brake Upgrades for RenaultSport Megane RS and Clio RS.

YozzaSport announces the release of a three stage brake upgrade package for the RenaultSport Megane RS and Clio RS range. The three stage upgrade consists of firstly, a YozzaSport brake bell with a two piece 312mm AP Racing Disc. The second stage uses the same YozzaSport brake bell but upgrades to a custom 330mm AP Racing Disc, using a YozzaSport caliper conversion bracket. The third stage removes the Brembo 4 pot caliper and replaces it with AP Racing 4 pot caliper ensuring that the 330mm disc’s braking potential is utilised completely.

Scalable Brake Upgrades for RenaultSport Megane RS and Clio RS.

With owners of Megane RS , 225, 230, R26.R, Clio RS 197 and 200 experiencing braking issues such as warped and cracked brake discs, brake overheating, pad material deposited on the disc resulting in juddering, pad fade and other issues, YozzaSport have brought forward their new brake packages for two of the most highly acclaimed road and trackday cars of recent years.

For YozzaSport, it is important, that these upgrades are scalable, affordable and are backwards compatible with the 2003+ Megane RS as well as the Clio 197 and 197 Cup variants, and as such we have designed these  brake upgrade packages to fit behind the 17” Clio Speedline wheel that many road users have as standard, and that trackday enthusiasts prefer over the 18” standard wheels on the Megane RS.

YozzaSport Stage 1
312mm YozzaSport Brake Bell/AP Racing Disc – £599

YozzaSport Stage 2
330mm AP Racing Disc & YozzaSport Caliper Adapter Bracket – + £669.99

YozzaSport Stage 3
4/6 Piston AP Racing Calipers & YozzaSport Caliper Adapter Bracket – + (from) £629.99

Stage 1 – 312mm YozzaSport Bell/AP Racing Disc – £519.84+VAT
Replacement Discs (Pair) – £399

This kit replaces the standard brake disc with a tangential cooling veined, 8 grooved, AP Racing 312mm disc and a custom YozzaSport brake bell.

The standard 312mm brake discs found on the Megane and Clio RS range are more than adequate for most road users, however, once the car is taken beyond the normal road limits onto the track or race circuit, the standard brake pads and brake discs are not as reliable due to the higher operating temperatures. Pad transfer issues, warped and distorted discs and caliper flex are some of the issues reported to us by customers.

The main purpose of the tangential vane design is to provide a cooling space between the disc braking faces, but if the vane design was a simple straight type or even a pillar design such as the standard OE brake disc, then the disc could become unstable at high temperatures.  The tangential curved vane provide superior support to the brake faces over the straight vein and pillar disc design, and lessens the risk of brake disc warping / vibration induced by high brake temperatures.

The 8 grooves in the disc ensure that any brake gases and dust is expelled from the braking surface and also create a clean braking surface on the pad to offer maximum surface contact area with the disc/pad.

Stage 2 – 330mm AP Racing Disc & YozzaSport Caliper Adapter Bracket – £829.99
Replacement Discs (Pair) – £499
Upgrade from Stage 1 – £669.99
Outright Purchase of Stage 2 – £829.99

YozzaSport 330mm AP Racing Disc and Adaption Brackets

YozzaSport 330mm AP Racing Disc and Adaption Brackets

This kit upgrades the brake discs to a 330mm x 28mm disc, whilst retaining the YozzaSport Bell from the 312mm kit as well as the OEM Brembo 4 pot caliper. With an increased disc size, there is increased stopping power, as well as reduced operating temperatures due to the design of the curved cooling veins within the brake disc. The AP racing casting is machined to specification for YozzaSport, with the grooves being machined into the disc to offer extremely high quality and high performance discs with the benefit of being a simple upgrade to our 312mm stage 1 conversion.

It is designed to fit behind a 17″ Clio Cup Racer wheel and clears the wheel shoulder with around 7mm to spare – as you can see with the picture here with a wheel weight clearing the caliper.

With YozzaSport machined brake adaption brackets included in the package price, as well as all of the brake fittings that are required to fit both the brackets and discs to the vehicle, the upgrade offers both outstanding value and performance.  The brake kit is intended to be the highest level of performance that can be achieved without making the investment in an uprated four or six piston brake caliper for the Clio and Megane RS.

Stage 3 – 4 or 6 Piston AP Racing Calipers & YozzaSport Caliper Adapter Bracket – starting from £629.99

Replacement Discs (Pair) – £499
Upgrade from Stage 1 – from £629.99
Outright Purchase of Stage 3 – from £1980

A P Racing Road and Race Calipers

For the ultimate on track braking performance for the Clio 197 and Megane RS the standard Brembo monoblock caliper, is not as stiff as a conventional 2-piece caliper. There are no bolts to connect the 2 halves of the caliper together; these help to reduce the distortion of a caliper under load. This means that the standard Clio RS and Megane RS caliper distorts more under braking and cornering producing the tapered wear patterns on the brake pad which some race and trackday users are experiencing with the standard brake components.

YozzaSport offer a full brake kit for the Clio 197/200 and the Megane RS 255/230 including the R26.R and F1 variants which utilise a variety of AP Racing road and race 4 and 6 piston calipers which are fully serviceable and offer the option to use a much broader selection of road and race pads over the standard RenaultSport/Brembo caliper.

Megane RS 250 Vs. Ford Focus RS 2009

The new autocar test and review video of the 2009/2010 RenaultSport Megane (RS) pitched up against the new Ford Focus RS.

It is interesting to note that many of the other magazines have pitched the FFRS against the new Clio 200 – despite the RenaultSport car to compare against is the Megane. The Focus looks to be quicker, but around a UK circuit it will be interesting to see how they compare.  I suspect that out the corner power will give the focus the edge over the Megane.

How to Stop Brake Fade On Trackdays

How to Stop Brake Fade On Trackdays

How to stop pedal fade and pad fade on trackdays

How to stop pedal fade and pad fade on trackdays

Brakefade is in essence the brakes ceasing to work. This often happens on track after periods or extended periods of heavy use.

There are two types of brake fade, that are essentially broken down into two specific areas:

Pedal Fade

Pedal fade occurs as a result of the brake fluid boiling in the calipers.  The normal resulting symptoms are that on application of the brakes, the brake pedal to feel spongy and pedal travel will increase. This is often called the brake pedal going through the floor. It is a particularly unpleasant experience, as normally when you apply the brakes you are expecting them to pull you up, often when “the pedal goes to the floor” you are hurtling towards something that you would rather not make contact with – IE Someone else, armco or other immovable object that will need more than T-Cut and a polish out…

Braided brake lines will also help resist the spongey pedal feel. Stainless brake line information is following in the coming weeks.

If you experience pedal fade, it almost always will require the brake fluid in the system to be changed, as it will have boiled. Once brake fluid has boiled once, its ability to resit boiling again has been greatly reduced.  Brake fluid testing should be regularly done as a matter of course, and on a track car or racecar, it should be replaced regularly, or when tests show it has degraded. (Always use the highest-grade fluid possible). The standard brake fluid now-a-days is dot4.1 however, dot5.1 is now quite common and is suitable for most trackday and race applications.

Pad Fade

Pad fade is the result of friction being lost between pad and disc surface due to the friction material exceeding its maximum operating temperature.  The pedal feel remains constant (ie. the pedal remains hard) but regardless of how hard you push the brakes, the vehicle is not slowed down.

If pad fade regularly occurs or if it occurs towards the end of a session or race, an upgrade to a material with a higher operating temperature should be considered.  If the highest specification pad material is being used, one should be looking at larger rotors (discs)  or a higher quality disc with curved vanes can also aid this cooling process. Alternatively, improving cooling to the brakes through the use of brake ducting or similar.

The most significant area of problems or issues with upgraded brake discs, pads and high performance braking systems is almost always the control of the brake temperatures.  The Brake disc and brake pad temperatures can be analysed and with this information, one can measure the temperature range the brakes are operating in.  With this information different pad materials can be considered, and cooling systems can be developed and tested to analyse whether any improvement can be made to the operating temperature and reliability of the brakes.

We can offer a number of upgrades to almost any vehicle, but you should expect to pay a minimum of £60 for a sensible Trackday pads such as a Ferodo DS2500 brake pad. (More information is available by clicking the link.)

Mintex offer a number of trackday compounds such as the Mintex M1144. (Again, please follow the link for more information.)

Pagid are also an excellent if not a more expensive solution to a trackday and endurance race pad, however, they are very much worth the money in my opinion.

New 2009 RenaultSport Megane 250 Unveiled At Geneva Auto Salon

New 2009 Megane RS

2009 RenaultSport Megane Unveiled At Geneva Auto Salon

With less than an hour to go until the revealing of the new Megane R26-R at the Geneva Auto Salon (Motor Show), the anticipation is starting to rise. With an expected 250 BHP the New Megane RS R26 is RenaultSport’s second escapade in as many years into the hardcore trackcar market.

With an accompanying press release and pictures to follow, ReadyForTheTrack will keep you bang up to date as soon as the pictures are released.

NEW MEGANE RENAULTSPORT: 250HP OF PURE PLEASURE

As the latest in a long line of Renault performance models, New Mégane Renaultsport 250 stands out through its exhilarating performance and handling. The fusion of its extra 25hp with unmistakable sporting coupé credentials and choice of two chassis settings (sport and Cup, the latter with a limited slip differential) is clear evidence that New Mégane Renaultsport has been honed to delight enthusiasts.

Coming after Mégane F1 Team R26 and Mégane R26.R, New Mégane Renaultsport 250 profits fully from Renault Sport Technologies’ extensive experience when it comes to manufacturing performance models.

Powerful
New Mégane Renaultsport 250 is powered by a new-generation two-litre 16-valve turbocharged petrol engine which boasts maximum power of 250hp at 5,500rpm and peak torque of 340Nm from 3,000rpm. The sum of the different improvements made to this engine has produced a gain of 20hp and 40Nm over Mégane R26.R which itself emerged as the yardstick in the world of performance hatches. The Renaultsport engine’s twin-scroll turbo is exceptionally responsive, particularly at lows revs, with 80 per cent of maximum torque available from 1,900rpm. Its wide power band makes it a genuine joy to drive in everyday use, and the pleasure remains undiminished all the way up to the rev-limiter whenever it is pushed a little harder. The engine of New Mégane Renaultsport 250 transmits its power through a six-speed manual gearbox.

Work has also gone into the acoustics of the Renaultsport engine to produce a tell-tale sporty note audible inside the cabin under acceleration.

Efficient
New Mégane Renaultsport 250 has inherited the same suspension arrangement as the current version. Thanks to an independent steering axis layout at the front, the suspension and steering functions have been separated to ensure a particularly high standard of handling allied with great traction.

Like the Renaultsport versions of the Clio and Twingo ranges, New Mégane Renaultsport is available with a choice of two chassis: the standard sport chassis or the Cup chassis, which comes with a limited slip differential for even greater traction.

The electric power steering features specific calibration and benefits from the latest improvements seen on New Mégane aimed at achieving greater precision and even more feedback from the road.

New Mégane Renaultsport 250 is equipped with ESP which is fully disconnectable in order to enable owners to enjoy their car’s full potential on a circuit.

Provocative
New Mégane Renaultsport 250 benefits from undeniably sporty looks. The front bumper incorporates the LED daytime running lights, as well as the splitter which recalls the low-slung nose of the R28 Formula 1 car. The dynamic looks are further emphasised by extended wheel arches and sills, 18-inch alloy wheels, central exhaust tailpipe and rear diffuser.

The interior design, too, recalls the world of motor sport, from the extra lateral support for the seats, to the analogue rev-counter with visual and audible gearshift indicator, the aluminium pedals and the Renaultsport steering wheel complete with thumb grips. The Renaultsport signature is also visible inside the car: on the headrests, rev-counter and dashboard.

Renault Sport Technologies has combined its experience of motor sport with its longstanding production expertise to develop a comprehensive range of sporting cars. The hallmarks of Renaultsport models are their pedigree engines and efficient chassis which together deliver an undeniably high level of sports performance, as testified by the reputation forged by Mégane F1 Team R26 and Mégane R26.R which were voted ‘Sporting Car of the Year’ in France in 2007 and 2008 respectively.

New Mégane Renaultsport 250 goes on sale in the UK later this year.
