So i just did a b18 swap and took the car out for a test drive, everything works perfectly fine, but when i punch it the car starts to wobble in higher RPM's but doesnt when driving normally. The cars allingement is fine and it drives straight but it still wobbles. Could it be the motor mounts? I put brand new axles on and triple checked everything so i dont really know what else it could be. anyone have any remidies for this? would getting some strut bars or traction bars help? anything would helps thanks a lot guys.

 

Are you sure you tightened it, it also could be the ball joints. Jack it up and see if you could wobble the wheels yourself. If not and it only happens at high rpms // with or without gas, I think your tires need to be rebalanced.

 

Could be axles, axle seals, or wheel bearings.
