Extra Brake Cooling, someone tested?!

[fredgroves]

Of course ducting is a great idea for high performance braking systems, aren't the scoops on the R for brakes?

[scanesare]

CS brakes are the same size as PP & R, & R performance

Only difference is that the CS discs are two piece & 1kg lighter each..also specific friction material for pads...

R Performance uses the CS discs & pads & adds a silver coloured badge/cap thing to the calliper like the red CS & GTI/PP...

Callipers, carriers, hoses, servo etc all the same for above..

Yes you are right  .

But what i have read from people that have upgrade to the CS brakes is much better, and this is the best upgrade you can do for the GTI.

CS (Clubsport) brakes are the PP/R brakes. I think you and Golfdave refer to the CSS (Clubsport S) brakes instead that feature a slightly lighter two-piece disc and different pads as mentioned. I don't think there is much performance gain in the discs themselves other than the slightly reduced weight, any improvement is down to the pads. From what I've read about the PP to CSS brake upgrade they are not really "much better" and definitely not "best upgrade you can do for the GTI". The difference is minimal and they are mostly selected by people because of their OEM+ character not their performance. I know I would not like a drilled disc on my car though.

If you want a real brake upgrade you are looking at pads such as Pagid that cost alone as much as the CSS discs and pads together, good fluid and lines as a first step, and then for serious track use a proper BBK from StopTech, Alcon, Brembo and the likes. Oh, and brake ducts of-course.

Yeah CS & CSS I tend to refer as the same..which they aren't my bad...

Point being as OEM it won't void warranty, as items made by "VW" for the Golf & will be perfect fit ...just the same as getting the dealer to supply & fit a different Golf alloy...so no reason why "Wide" can't do it....

Personally I wouldn't even consider the PP/R/CS/CSS/RP 340mm discs with a heavy single piston sliding fist calliper to be anyway "performance"....

Seat were fitting 4 pot Brembos to the Cupra R cars years ago & they had way less power!!

Vagbremtechnic??...do various nice kits including small 4 pot kits etc....they even sell the two piece Clubsport (CSS) discs for about £350

Anyway brake cooling with air guides etc is very beneficial & the "R" has oil coolers in those big side grills I think...as defo not a "though" duct from when I have looked at them in person..

Yes, I agree that their OEM character is the biggest attraction to PP/R owners, that and the fact lots of people think of drilled discs as an uber-performance item...

I also agree that neither setup: PP/R/CS or CSS is a real high-performance brake setup. But I can understand the choice on the basis that none of these cars are race-focused models either so why raise the cost? The Cupra R (previous gens) has always been a more hardcore animal on purpose, this actually used to set SEAT apart from the rest of VAG brands (not any more). And I don't think power has much to do with it. A big multi piston setup offers probably minimal reduction in actual braking distance. What it offers is more even pressure, better feel and control and more importantly: Endurance. Are the PP/R brakes strong enough to stop the car adequately? Yes they are, I have been much impressed by them. Can they do it repeatedly for 2hr on a track? No way, but that's not the purpose of the car anyway. The 4 piston Brembo setup on the Cupra is not without its issues also. You can't fit almost any 18" wheel and have to run 19" winters and several owners have discovered cracks on one of the disc as they are not symmetric and one side's cooling vanes are always rotating the wrong way. So all things considered, maybe VW's choice does start to make some sense in the end.

Those are nicked from the Audi TTRS I think...& at that size should be 6 or 8 piston...& no I would NOT recommend those either...you can get very powerful 340mm size 4 pot kits.....& I would get "J" hook discs..or some grooves but not drilled...

£350 ish a pair of CCS discs then the pads on top for a hassle free & 2kg (total) weight reduction is a very nice job...not the best, but better...but how much more to spend to get what I would recommend??....4 to 5 times??

Thank you for all suggestions guys !. I will start with these brake ducts. The car worked great to drive 15min stint on the track with the original stuff with, which is enough. That it started to burn was that rubber tires came from the track on the boards and took fire. It would have been a nice movie, but I missed it ..

And i like OEM stuff, i have tested to much crap on early cars . therefore CSS brakes are interesting..

Soon a review  ...
