BBK pad advice for hard track use

[Franzino]

I only tested EBC once on my e46 and found it rather crap...no way I would fit these on my car that sees intense track usage (personal opinion).

I had my Z4M from 2010 until the end of 2018...the car was fitted with AP brakes and extra brake cooling ducts (see picture) from 2011 (full BBK front and rear). These brakes are awesome (with the right pads). I experimented with different Pagid pads during the years (I drove 80% Nurburgring / 10% Spa / 10% Other tracks). The best braking power, best brake balance and awesome initial bite was with RS-14 (front) and RS4-4 (rear). After a couple of year I switched to RS-29 (front) and RS4-4 (rear). Because RS-29 is a bit easier on the discs then RS-14 and you only lose a small bit of less initial bite (still awesome braking power and awesome brake balance). With RS-14 I had some premature big cracks in the edge of the front AP rotors (got them replaced under warranty from AP)...but switched to RS-29 to prevent this in the future. I never had any issue's with RS(L)-29 on my Z4M and on my M2...and I'm a heavy and late braker on track.

As some side info....the top pads are the one in my M2 (standard brakes) and the bottom are the one of the AP brakes of my Z4M. Same contact area in size but different approach (4 piston vs 6 piston).

Thanks Franzino, that’s really useful

How are you finding the M2 as a track car vs the Z4M now you’ve had it for a while? I’ve heard conflicting reports. I know an aggressive but not very sympathetic driver who keeps having problems with his on track (ranging from the engine overheating through to repeatedly cooking the brakes), and I also know a retired professional racing driver who absolutely loves it in manual guise and rates it against his Elise as a track car.

On my daily driven 2006 Z4M Roadster I have an AP Racing Radical BBK from Essex on the fronts, stock Z4M calipers in the rear. I have ECS Tuning rotors in the rear, but they are stock size (they just have a replacable rotor). The only performance mods are the BBK, an Eventuri intake, and Apex ARC-8 18" wheels.

I have been running Ferodo DS 1.11 pads on the front, and DS.2500 pads on the rears. If there is a gap in between track days, I will swap in DS.2500 pads on the front for daily driving.

During track days, I turn traction control off completely as I found that leaving it on causes excessive wear on the rear pads.

I did use DS.2500 pads on the fronts, but find they wear out too quickly when used agressively on the track.

I love the AP Racing brake setup. I think I will swap out the stock rears for an AP Racing Radical setup from Essex. I will think about that after I do a coilover upgrade.

Both compounds of Ferodo pads generate a lot of dust. The 2500s wear out pretty quick even when just used on the rears. The DS 1.11s are enduro pads and seem to have good life. They last well on the track, I've not noticed any material degradation during 20 minute track day sessions.

Hope this helps and happy to follow this thread and learn from it.

Cheers,
Eamonn

I ran Pagid rs29 on my supercharged m3 with k-sports and they were miles. Better than the blue.

I also swapped out blues on my e36 m3 track car for CL rc6 and again a massive improvement in feel and durability.

I have also had success with carbotec xp8 and 10.

Ebc have just launched a new track pad but I’ve not tried it yet.
