MY evo is a full blow time attack evo. making about 640whp and 540lbft.
I have A quarter master twinplate for awhile now. The evo drive normally fine. with not a single issues, but soon as i WOT the car feel like wheel hopping violently. my differential doesn't make sound. Before i go out and spend my money, i just to make sure it's clutch.. thanks

 

bump for answer

 

The clutch would be slipping as a normal failure mode. I would look elsewhere to diagnose bucking/jerking.

 

clutch slipping can be tested in 5th gear from 50-60mph then wot... if it slips you will see it

 

How are the axels?
