RenaultSport Clio 197 and Megane RS Brake Discs, Pads and Callipers
RenaultSport Clio 197 and Megane RS Brake Discs, Pads and Callipers
The RenaultSport Clio 197 and Megane RS brake disc and pad options are few and far between. Both the Clio 197 and the Megane RS (including the Cup, Trophy, F1 R26 and the R26.R) share the same 4 pot Brembo Calliper and disc combinations on the front, so therefore – what will fit on the front of a Megane will also fit the clio.
The brakes are a big improvement over previous generations of RenaultSport Clios (with the exception of the Clio V6), with a much bigger disc and 4 piston (4-pot) caliper rather than a single piston caliper as found on the Clio 172, the 182 and the older generation RenaultSport cars.
The discs are vented312 mm x 28mm on the front and vented 300 mm x 11 mm on the rear for the Megane and on the rear of the clio, the only difference is the 300mm non vented solid discs.

Generic – For All Clio’s and Meganes with the Brembo 4 Pot Caliper:

What Aftermarket Parts are available?
AP Racing / YozzaSport
AP Racing Disc YozzaSport Bell
AP Racing have a two piece disc solution that YozzaSport have worked on. We use their discs, and our own bells, as the price for us to use the AP Racing parts was just prohibitive for the price of the kit. AP recommend that their discs are used with a compound like the DS2500 or one of the Pagid compounds. In my experience the carbon lorraine compounds that are available just eat the discs. I had a very upset Frenchman complain that the discs were too soft a number of months ago… It was more along the lines that he was using a very hard agressive race compound and with no cooling in the standard arches, everything was getting rather hot.
The AP Racing/YozzaSport kit (P/N CP4590-011BNP.CG8) is £649 for the kit & then £344.78 for replacement discs thereafter.
Brembo
Brembo GT Brake Kit for the Clio 197 and Megane RS
Brembo offer a number of components for the two cars.
A Brembo HC brake disc is one of the universal components that they offer – it is simply a replacement disc to the standard Renault OEM disc.
Brembo also offer a GT 4 pot brake kit, which replaces the single piece caliper with a 2 piece caliper, and offers you the choice of either a slotted disc or a drilled disc. In total there are four kits that they offer, prices range from £795 to £1250 depending on whether you go for the one piece discs, or the two piece bells and rotors.
YozzaSport
Obviously as I have mentioned, YozzaSport offer the 2 piece disc kit in conjunction with AP Racing, but we also offer out own Stainless Steel Braided Brake Hoses/Lines.
Stainless Steel Braided brake lines for the clio and megane RS
The Megane and the Clio both suffer with brake fade on track and the braided brake lines that we offer can eliminate this issue. It is obviously important that you also use good quality brake fluid and that you change it regularly.
K-Tec Racing
K-Tec also offer a 2-piece grooved disc I have just noticed.
Brake Pads
The choice of brake pads isn’t particularly wide. I would recommend that if you are planning on changing the pads that you also get these items in stock – as you will probably end up needing one or all of them…
Caliper Service Kit – 7701208118 - £24.36 (You should get two of them if you are changing your pads – as the pins have a tendancy to seize and to bend)
Brake Pads – 7701208218 – £92.50 (I wouldn’t bother with these – uprate them – see below)
Bleed Nipples – 7701209424 – £3.50 (Also well worth keeping in stock if you are out on track a lot)
The Renault original pad is obviously intended for road use. If you are finding that your brakes are starting to judder then it is normally pad material deposited on the disc surface, and the best solution is to go out and thrash the car for 5-10 minutes, using the brakes heavily, and then letting the system cool down whilst you are driving. This should eliminate the vibrations. However, it is also quite common to warp the discs on the 197 / Megane, so be warned – it could be expensive.
My best recommendation for pads is the Ferodo DS2500 – it is almost the same price as the Renault pad, and is much more agressive when being used hard. Price is about £110.
Other alternatives are as follows:
Carbon Lorraine
(Very heavy on discs)
Pagid
RS5
RS15
RS29
Endless
RenaultSport Group N tarmac rally front pads.
So in essence thats it. The complete knowledge about the brakes and everything that is available for the braking systems for the Clio 197 and Megane.
I might well add a few more details to the brake pads sections in the coming days,

RenaultSport Clio 197 Camshafts Available
Clio 197 Camshafts
Road and Race Camshafts are now available for the RenaultSport Clio 197. Some significant gains have been shown over the standard clio 197 now, so I feel it is worthwhile sharing the information that we have on the products currently available.

Clio 197 Re-Maps and Group N Custom Mapping
Mapping the 197 I would suggest speaking to Henk at FastChip in Holland – 197 Custom Mapping He is blooming excellent with the mapping on all the RenaultSport range.
Or alternatively;
The guys up at RS Tuning in Leeds have done some work on the 197 with CatCams. You have two choices – do it yourself or take it somewhere to be done, either way, I think that you should see some good peak power and accross the board gains.
Catcams UK provided me with a power graph for a car that was run up by RS Tuning recently – now, the stock power figure does look a little low, but every set of rollers gives a different reading on the day, so I would look at the increase, rather than the headline figure. See Below:
Anyhow, I hope this interests you enough about the 197 Engine tuning and modifications that we can supply.
Allways a Hooligan,

RenaultSport Clio 197 R3 Maxi Rally Car
A NEW ACCESS VERSION FOR THE CLIO 197 RENAULTSPORT R3
RenaultSport Clio 197 Maxi R3 Press Shot 1
Clio Renaultsport R3 Access is the new entry level version of the R3 Maxi – developed for customers wishing to compete in rallies. Renault Sport Technologies has used the R3 Maxi as a base to produce an extremely competitive Access version which has opened up the world of rallying to an even wider audience.
The 2007 season saw Renault Sport Technologies introduce regular changes to the specification of Clio Renaultsport R3 Maxi in collaboration with its customers who in turn profited from the reliability and performance potential of the brand’s latest rally challenger to secure some 20 two-wheel drive category wins, including two overall victories.
RenaultSport Clio 197 Maxi R3 Press Shot 2
The 2008 season has seen the Clio Renaultsport R3 range extended with the introduction of the entry level Access version which enables rally drivers to compete for a lower initial investment and on a third of the budget required to campaign the Maxi-spec car.
Clio Renaultsport R3 Access shares many of the Maxi’s basic features, including a Clio Renaultsport bodyshell strengthened by a welded roll-cage incorporating more than 40 metres of tubing. The clutch, six-speed sequential gearbox and limited slip differential are also common to both models, as are the steering rack, the electrical system and the Magneti-Marelli ECU which incorporates the data acquisition system.
Clio Renault Sport R3 Access benefits from the very latest developments, including a new reinforced subframe. The 1,998cc F4R RS engine (4 cylinders in line, 16 valves), which is derived from the powerplant of Clio Renaultsport 197, develops peak power of 200hp and features a specific camshaft and exhaust manifold, while the flywheel is the same as that seen on the Maxi version.
Developed exclusively for tarmac rallying, Clio Renault Sport R3 Access uses the same suspension of the standard car with strengthened struts and specific kinematics for the independent steering axis front suspension. The newcomer is fitted with Bilstein dampers all-round and profits from the high performance braking system featured on Clio Renaultsport 197, with standard front discs and four-piston Brembo callipers.
The one-piece aluminium alloy 7×17-inch Speedline wheels and Michelin 19/62-17 tyres are identical to those of Clio Renaultsport R3 Maxi.
There is no mistaking the competition pedigree of the Access version’s upper-range interior which sees the gearshift control positioned right next to the steering wheel.
The kit also features Sabelt safety equipment, most of which is identical to that of the Maxi version. The standard pedal assembly has been reinforced.
To enable customers to improve the performance of their Clio Renaultsport R3 Access as a function of their ambitions and budget, it is possible to upgrade the basic spec thanks to Premium kits (chassis, brakes and engine) which ultimately permit it to reach the same specification as the Maxi version.
As with all Renault Sport competition cars, the Rally Customer Competition department provides a broad range of services, including the extranet website which provides all the documentation required to build the Access and Premium kits.
The Clio Renault Sport R3 Access kit, including all the specific parts to be fitted to the car, comes at a pre-tax price of €32,600 in France. The cost of competing is estimated to be €17 per kilometre.
