Has it been lowered at all? Your driveline may need to be aligned...

Check motor mounts, I had the same prob and did the same things, than I pulled the motor and there it was a broken driverside mount, mine was bad at 130 to 140 kmph

id say check alignment and balance that should cover everything. most of the time that is what the problem is.... when hit the brakes at like 30 does it pull at all.... dont slam em just put some pressure on them.... if it does then have it aligned anyway and that should fix your prob.

Hummm If life was that easy...^^

OK I have found out what the shaking is all about it was the rear back wheel is alittle bent, So now I am looking for a wheel
