CL6 pads or 4 pot upgrade?

[Matt555]

Unsure which direction to go with my brakes.... I'm currently running CL5+ pads with Brembo HC discs and considering upgrading. The car is primarily for track - from what I've read on here the CL6 eat discs and produce a lot of dust which doesn't bother me, just interested to know which option will give the best stopping power. For reference I'm running 15" wheels so the 4 pots will have to fit under these which as far as I can find gives me the options of modifying some Brembos or getting a wildwood kit. I don't want the hassle particularly of modifying the brembos to fit so I think it's either CL6 or wilwoods with a suitable pad. Anyone have any opinions on these options?
Cheers,
Matt

I have been using RC6 for my last 4 track days and the stopping power is fantastic, Oulton park finished them off.
With the pad material getting thin I think the extra heat melted the rubber piston seal so I need to rebuild the callipers now, the discs are fine but even if they do wear quick that would not bother me anyway as they are so cheap.

It was the day llast week at Oulton Park which highlighted I need better brakes, as the car was quick enough but braking was a bit iffy at points. Think I'll give the RC6 ago before shelling out on 4 pots

4 pots will perform better over the day and pads are nearly half the price compared to track pads in the oe set up, but the initial layout is high for 4 pots and discs are also quite expensive compared to oe. If you have the money to buy and maintain and it's a long term project then I'd say go for it. Think the willwoods are around £650 with discs, pads and lines last time I looked. I've got a set of Compbrake 4 pots to fit so will let you know how they feel once fitted.

I will be using rc6 pads on front and rc5+ pads on the rear.

Will be good to see how these perform, and then decide whether to go for the 4 pot upgrade aswell.

I had a set of Compbrake B4 4 pots fitted, I now run standard calipers, goodridge braided lines Brembo HC discs and CL RC6 pads. Stopping power is great, even more so with my R888 tyres fitted!

IMO Clio 1*2 don't need 4 pots, however I do miss the lightness and looks of them though so may fit some Brembo 4 pots eventually :wink:

 

[Matt555]

Thanks for the opinions. Pretty much decided on braided hoses, cl6 and some stickier tyres to go with it.

Yeah the r888s are just awesome but will eat brakes up much quicker than road tyres, my brakes where holding up on Friday at Oulton with my Pirellis on, then within 20 laps with the 888s on they just disintegrated to the metal. I'm in 2 minds whether to sell my 4 pots and go with something similar to your set up....

all i will say is rc8. job done

4 pots although good, are not really needed, I and many others race on standard calipers and discs.

Just the sort of opinion I wanted. Cheers guys

how did you get on this afternoon?

205 powers 180 torques, feels a lot more responsive, and sounds a lot less like artillery fire on over run.

good result!! was saying to chris about the throttle body cough when they are poorly.

got a pic of the graph?

 

[Matt555]

204 and 172 to be precise, sure it was 177... I blame the beer . Chris said the original map wasn't bad just not tailored to the engine / manifold I'm running which is what I expected. Want some cams fitting next and see what we get then

no rush for cams with those figures.

True, 865kg ish, it's fun. Brakes first and the remaining bushes to change, then cams. From the conversation you were having I gather you could do the cams for me?

 

[bloke]

yeah, can do. sorry i didn't natter much, had a manic couple of weeks and was trying to switch off!!

 

[Mash.]

I didnt get on with 4 pots in my 890kg 182, love my rc6s currently although yet to get on track with them yet.

How come to aggressive?

How come to aggressive?

They're good enough as standard let alone a Clio that is nearly 200kg lighter than standard.

No modulation on braking, couldn't properly heel toe, yeah just used to grab the disc and not let go, maybe they would of been good with slicks haha. (using direzzas) but yeah no doubt they're great for a clio with a bit more weight or a 300bhp plus carrying a LOT more speed into a corner.

Cheers bud, got a set to fit but tempted to sell them and use RC5+ pads on HC discs....

That's all i use mate.

Its really all personal preference, if its 2nd hand and youve got it all there i would fit them and see how theyre like, if you feel you would be better off without them, sell them have £400 in your pocket to spend elsewhere

Havent tried rc5s but rc6s are excellent

This has always been my thought, the caliper has been designed to perform to a "high" standard with the factory weight of the car. If you strip a car of any weight surely the brakes have less weight to slow down, thus meaning they're better without even changing pads or discs for uprated versions. All you need is better pads, I have always seen BBK's as overkill on cars, more so road going cars that never see speeds above 70-80mph and spend 80% of their life stopping a car at 30.

The terminology used by the general public regarding brakes is horrendous.
There are three separate issues being discussed here and they're all mixed together.
1) Pad choice - This is independant of caliper choice and depends on the temperature range seen in operation which is affected by vehicle weight, cornering grip, power and disk size mainly. If you're running RC5+ and only change the calipers, the odds are you'll want the same again. Depending on the caliper they may be a a different price but that's it.
2) Disk size - upgrading the braking power by increasing the lever arm. Not really been discussed here except in the last post, but might happen as part of a 'brake kit' if one is purchased. If braking power is acceptable at the moment, its just more weight. Also the OP refers to 15" wheels, so it basically isnt an option.
3) caliper choice - where this started. Since most people match the piston sizes in order to keep the same master cylinder and so on, there is no gain in braking power. You might get marginally better heat dissipation, and more even pad wear, but the main advantage is feel.

So really its not a question of "new pads or 4 pots" its more "I'm buying new pads anyway, shall I do the calipers at the same time". If the car has plenty of stopping power prior to getting too hot, and the brakes feel ok to you, but then it later suffers due to getting too hot, then surely new pads in a higher heat range are the obvious choice....
