Are spacers required for Brembo BBK ?

DaveDee · 07-11-2013, 01:08 AM

Thinking of installing a Brembo 380 front and rear BBK on my E92 M3. I have BBS CHR-19's fitted (Front 9" rears 10.5") Rear tires have only 5mm clearance each side (295s) and I'm taking those up to 305's

Does anyone know if spacers re required on the rear to fit the 380 BBK?

nope, brembos will fit fine behind those wheels

these are 380 brembos behind CH-R 19s

Thanks for that, just the info I was looking for, mainly info on the rear brakes

If it clears the front it will clear the rears. The fronts typically have smaller offset on staggered setups, and even if non-staggered setup, the rear has significantly more axial clearance compared to the front.

Good luck with 305's. I don't think they will fit. You may have 5mm clearance on the top but the rubbing will occur towards the front of the fender (9:00 - 10:00 when viewing the car from the driver's side). You may be able to make it work with a tire that runs narrow but a PSS or AD08 not a chance. I have 10.5 et25 wheels with 295/30/19 AD08's and there is 5mm clearance on the top but mm's away from rubbing in the above listed location. I previously ran et22 on the same tires and they rubbed. In other words we are talking somewhere between 1 - 3 mm clearance.

This is absolutely correct.

The 305 will simply not work and will rub to the point of melting the paint on that panel severely.

Thanks for the heads up guys, I also have H&R springs which I guess will aggravate even more, currently the 295 PS2s are not problematic
