gt shaking

[Ryan441]

while driving the car shakes at a certain rpm i can get it to not shake as bad. while slowing down i turned the engine off so i could listen and there is rattle or clunking noise coming through my feet. the car accelerates hard through first and sometimes second but if im already moving i hit it in third and it hardly pulls and shakes really badly

Good call on the trans mount, the stock ones are JUNK. Get a poly mount. Also, adjust the clutch.
