So had my new KRB-GR2s installed, as well as Brembo solid brakes all the way around (both) on my car couple of weeks ago.

So now whats happening is my car shudders when driving, but only when my foot is off the gas. When I step on the gas, no shudder. When I brake, no shudder. but when I step off the gas (no brake), the car is jittery.

Any ideas? The brakes seem to work fine when used, and the struts seem to be cushioning bumps, etc nicely but the car jitters when the gas pedal is stepped off of.

Thanks.

Did this problem arise immediately after the install?

I remember my friend didnt torque down his lugs and it drove like that, we got out and his lugs were loose as hell.

doesnt seem like its got anything to do with the shocks or brakes if its only on acceleration.....unless, like mentioned above the wheels arent tighned, or maybe u didnt tighten the caliper bolts, or its an engine problem??

Yeah happened right after the install. Will check into the lugs, etc.

make sure your strut bolts are tight as well. Its always the stupidest things that make you go nuts.

If you have your old rotors, and you cant pinpoint the problem, I would switch back to my old rotors and see if it's gone. This way you can differentiate if it's your suspension or if it's your brakes.
