What would cause a hard jerking when you take off. It only happens if you give it a little gas when taking off. pretty much 1500rpms-2500rpms. It makes the whole car shake but doesnt do it if you take off nice and slow. The guys that did my motor swap and clutch sanded the flywheel because they said it was glazed. Could they have sanded it too much in one area so its grabbing unevenly?. There is no vibrating or anything once you are moving and it doesnt do it when you shift into 2nd through 5th. I ordered a Fidanza 7lb flywheel to replace the stock one and the clutch has a lifetime warranty so I am not worried. I am just curious if they intentionally screwed it up because it didnt do this with the old clutch.
