E30 M3 Brakes

These are the down fall to this amazing motor. I was traking mine last year with standard pads and discs. These were warping at the end of the pit straight at Knockhill. After some research i have opted for the Zimmerman x-drilled discs all roung and Hawk HP Plus street and ATE super blue. (i would prefer 4 pots, but want to keep the vehicle standard looking)

After one track day evening at Knockhill with 3 20 min sessions this setup never once failed and actually improved the hotter they got. They also work very well on the road as well. If you need an upgraded without having the dosh for 4 pot setup try these.

Happy Braking

Yeah, can back up lancelotII, cross drilled fronts not recommended. Mine went at the 'Ring, lucky to drop on a set of standard discs so play resumed.

2 years road use no problems, 3 sessions in Oulton Park with Ferodo 2500 and that's the result. I am running Zimmermann plain disks now.

215m3,

I have found the same as UweM3, but on other cars, that cross-drilling weakens the disc and makes it far more prone to cracking - Whether or not they are cast into the disc they are still going to be the weakest point.

I also find that the option listed by lancelotII is the best way forward (without going to 4-pots etc.).  On my track 205Mi16 I run quality std. discs with Ferodo DS3000 pads - NO fade, but the downside is alot of dust (with what appears to be a high metal content, so not really suitable for use on the road - They would kill your wheels).

My E30 M3 has drilled discs (on when I bought) which will be replaced soon with std. (once killed @ Knockhill!!).

PS What TrackDays do you do @ Knockhill?  Are you going to the Crail day on 31st May?

I am going up to crail on the 31 May, but not tracking.

I track at Knockhill with a chap who organises it mainly for Porsche's, which seem to have x-drilleds as standard, but they don't seem to have cracked from what i've heard. The next event is 28 May starting at 5.30pm with track action from 6pm. Booking is in advance but i think this event is always over subscribed so not sure if there are any spaces. It great to see this car mixing it with the 968 cs's and 964 and 993 through the twisty bits at Knockhill. i popped in too see the last top marques track day but it was just elises and type r's so not the same atmosphere at the one i attend. If you go i am normally the only e30 m3 and is red.

The hawk pads i'm using are fairly high metal pads and keep biting the harder they are pushed. I have all of lancelotII setup bar the discs and ducts, as i'm wanting to keep the standard look.

The Guy you need to speak with is Ian Griffiths at Kirby vacuum cleaners in glasgow. yell pages has the number. The lady that answers the phone will know about the track days. It is only limited to 35 cars for each event.

Good luck

Cheers UweM3

Well i've got them on now so will see how long they last. Knockhill is quite hard on brakes so let this be a test. Next track day is on 28 May so will keep an eye on them. The good thing about these track days is their not all day so they only get 1 hours trashing to hell and back in 3 sessions.

I cracked my front Zimmerman cross drilled discs on the street with EBC greenstuff pads. I still got C/D on the back but  as the doing far less braking and are a solid discs too, I guess thats helped.

I got slotted on the fronts with Pagid fast road pads all round as the EBC where pants!!!!

Been  find on the road , but that might all have changed after Monday at Brands!

I haven't had my M3 for a month now.. been at PowerStation having some 'stuff' done

I'll le tyou know how the brakes go after my first track day but I've only ever heard great things about G88's on other cars... grooved not drilled so much better than the Zimmermans...
