Car rocks back and forth on a full stop

ThatRWD · 08-01-2015, 02:16 AM

My car is a 2007 E92 335i 63K 6AT with KW V3 coilovers, PSS tires.

Sounds like your coilovers may need adjusting to a stiffer setting...

ThatRWD · 08-01-2015, 03:08 PM

Theyre at the max kw suggests to have them at.

Tom Droze · 08-01-2015, 03:57 PM

Not knowing your mileage, my guess would be it's time for a full bushing replacement.

Fundguy1 · 08-01-2015, 04:02 PM

Weird. Mine doesn't do that and I'm at 212000 with original everything suspension wise. Still rides firm.

ThatRWD · 08-01-2015, 06:26 PM

Damn E93 N54 at 212,000m. Nice.

I do have different brake pads in the front and rear. But I've had that for a while, it didn't start until recently.

Fundguy1 · 08-02-2015, 02:51 PM

Feuer, you're the brake genius here. Can I get away with 328 rear brakes and F30 fronts? I want the 328 so I can mount 16" drag slicks. I have stoptech brake pads now. Going to swap to cool carbons. Will these work also with the setup?
Thx

No, because e90 328i utilizes smaller parking brake shoes. You can use the e99 328i caliper and carrier combine with rotor from older 5 series. I discussed this already in a different tread. I will try to find it and PM you the link

Fundguy1 · 08-02-2015, 07:51 PM

I was planning on replacing all calipers, pads, and rotors. My concern is the bias and the large difference front to rear. Probably fine but better to ask. 328 brakes rear, f30 front. Cool Carbon pads, stop tech or similar slotted and drilled rotors. I know drilled is for aestheticsale and makes them more prone to cracking under severe use but it won't be tracked more than once or twice if ever.

From the e9x 328i only the carrier, caliper and pads would work. The rotor will not. You can balance the bias with brake pads. From my VW days I know Adams Rotors. Check with him. I'm sure he can custom match any slot/drill pattern you want.
