I just bought a 2001 gtp , i have always wanted one and sold my bmw to get it however after driving it for a couple days i have notice a pretty good shutter when i exellerate . The transmission shifts smooth and the engine runs great, if feels more like something in the front end. I took it to Carx today and they said my control arm is bent so i went ahead and ordered a new one . My question is could a control arm be causing this or could it possible be something else? thanks for any info.
