Front end of car shakes when braking hard

alpinewyte · 03-20-2024, 02:00 AM

I recently installed H&R lowering springs and when I brake hard from 70/80mph down to 30/40mph, the whole front end shakes...

I haven't had a wheel alignment since getting the springs installed since I'm still trying to have the springs settle a bit.

I checked the rotors/brakes, seems to be normal.

Steering and spirited driving all seems to be normal.

Could it be the alignment?

Lowering springs will introduce some negative camber, which causes some straight line instability, especially when transferring so much weight up front during hard braking. A proper alignment will help for sure, but not sure if you can make it as stable as stock.
