This is something thats been nagging me for ages and finally iv got around to it.
The standard 2.0lt Z4 brakes are actually really and perform well but for vanity reasons i wanted to change them, especially since fitting the ZM wheel's last Summer.

I found a guy on ebay selling a pair of BMW 3.0lt front callipers with carriers and snapped them up for £70. He assured me they where ready to bolt on and had only done 40k miles, i already knew id rebuild them, but when they arrived and sound dead spiders and cobwebs in them so i guessed maybe they had only been on a car that had done 40K but they must have been on a shelf for 2 years, lol!

So i too them apart, wire brushed them down all over, removed the piston and the seals, washed them in Washing up liquid, left them to dry and then sprayed them with silver Halfords calliper paint and left them to dry over night.

Excuse the front bumper damage, some C*@t did that in a car park and drove off, thats my next job to sort.
 
No real noticeable difference really. Still letting them bed in before I deliberately do any emergency stops.
The standard ones where more than ok. I'd guess there is no difference in day to day driving, the only real difference will be there ability on a track being used hard, they should resist over heating fad better.

Love the thumbs up picture besides the disk :lol:

I m tempted to get some drilled disks when mine need changing.

That looks really good top job.
I got standard grooved discs and i would recommend drilled over grooved there is a small amount of vibration under long heavy braking. I have checked everything i am guessing its the nature of grooved discs.
 
I'm already thinking of swapping the rear disks for drilled ones, sticking with the standard 2.0lt Calipers.
