Hi all,
I've got EBC rotors and green stuff pads on my track car, question is do other racers ie PBMW run these and if so have they ever run out of brakes( ie not been able to lock up the fronts?)
I have found them to be good on the track days I have done but without being able to run up against another e30 of roughly the same weight etc I can't tell if I'm braking late enough to get to the bottom of the brakes. quote often you are against production cars weighing a lot more and I've always been able to out brake them I've taken my own road car ( 208hp R53 BMW mini with JCW suspension and brakes) and I soon cooked the pads and warped the discs
A lot of people seem to upgrade the brakes, my question is...is it proved that you'll be quicker with bigger rotors and calipers?
Don't want to change from my 15 inch wheels and go bigger bakes unless its really a limiting factor
Trackway/ race disc brakes

Interesting problem...
There are several limiting factors that you need to consider before looking at larger discs:
1. Tyres
2. Temperature of the disc
3. Temperature of the brake fluid
4. Brake balance
5. Hoses (are you running rubber or braided?)
6. Brake pad area and piston area
I would have a look at the above before making any rash judgements on brake disc size as there are many improvements to be made before going for larger discs. A search on here might reap some rewards!
Good luck!

Hmm from experience the brakes on my car aren't yet the limiting factor, I am in the process of building a 2.8 stroker which I'm looking for 205 hp but more importantly much more torque, I think I'll see how I get on, I already have small bore steel braid pipes and brake cooling ducts on the struts and I'm considering flexible ducting into them. I've found them to be good. My brother has a mental vauxhall nova (with a 9k screamer 1.4 engine 200 plus hp) with a big brake set up with massive wilwood calipers and he's found that he's cooking the grease in the bearings on the hubs resulting in premature bearing failure, as always upgrading on part of the vehicle exploits another weakness!
Hi Paynts,
I compete in the Pbmw championship and use EBC Turbosport Grooved discs (vented) on the front and standard on the rear.
Last year I used Yellow Stuff pads matched front and back, the discs are approx 6 meetings and 3 track days old and haven't suffered warping. The rear pads do wear at a quicker rate than the front on a standard non bias valved set up (bias not allowed in Pbmw hence why some still run rear drums for more adjustability).
Ebc are introducing a brand new Orange Stuff revised pad which is better for racing/ track use than the Yellow, I tested the new pad at Snetterton this year in my Compact Cup car 318Ti and couldn't fault them. The new Orange should be available for the E30 soon.
Carbon L's were fitted to my Pbmw early last year, didn't like em.....too snatchy on a hard compound resulting in lessfeel, more lock up.
Pagid Rs29 were used at Rockingham last month and were the best pad that I have used yet.....but they should be for£££££ . Feel free to have a look at my on board camera footage on youtube 'Matt Smith 99 pbmw Rockingham'
Ferodo DS3000 will be tested on the 26/6 at Cadwell

I had a similar problem when using yellows on my track car, although this is with 4 pot calipers and 280mm discs, I have since used different (more expensive) pads and found them a hell of a lot better

RS29's are my vote.
