I just installed a new header, hub centric wheel spacers, oil pan gasket, 10.2 mm plug wires, intake piping, ported by 1mm intake and polished deleted all emissions iacv... black black, and some strut braces and chasis support. After it was all done I go drive and it feels like I'm in a washing machine on spin so I took the spacers off put wheels back on and the problem was still there so I started removing brces and trying to track it down. No loose bolts motor mounts are good granny mounts are good my drive shaft has a lot of play in it. Like you can grab it and turn it about 1/2 inch before it catches in gear not in gear doesn't matter so I ordered. Z1 lightweight drive shaft to see if thts the problem.. any other ideas?

Clutch is spec stage 3
Flywheel is fidanza
both have about 1500miles on them
Thanks guys
