BBK Comparison Test on E92

[Clubber]

Just saw this,

German magazine Auto Bild tested most of the popular BBK's on sale on E92 M3 and came up with very surprising results. Although it is an E92, I wouldn't think the results would be any more different on our cars. I have a new found respect for Stoptech now.

Check it out.

Thanks for posting. Very interesting!

The pfc is very light, are this "New" Set avaible for CSL or will this size fit a csl?

I'd be much more interested in continuous performance and brake cooling after heavy use than stopping power tbh

Overall, AP still looks like the best solution. Especially with RS-29 pads.

What were the pads used on the brembos ?

Pedal travel issue. Sounds like bad bleeding.

My brembos are much better than the AP.
100%

Since when did AP's ship with RS29's ?

The test car looks like some kind of race car, I wonder if ABS is deactivated? If not I'd be interested to know how the vehicle's ABS system copes with each of these brake upgrades. It certainly won't be deactivated in a lot of punters' cars.

For one thing, if the displaced volume is different, the modelled pressures will be different from what the ABS expects and it'll either be putting too much pressure in or too little. The increased friction is also going to mess with the brake torque calculations and could cause the vehicle to think the wheels are in slip before or after they actually are...

I'd really be interested to see if this is a consideration when essentially fitting race brakes to a road car.

My car has the AP kit and I swear it goes into ABS earlier than it should and is potentially sometimes being held back a bit under really harsh braking as a result.

I don't ever recall the abs kicking in with my APs
