thats an interesting point datsik...

and im thinking that the slack im taking up is in the output shaft of the gearbox...

it has noticeble play in it when u grab the tailshaft by hand and wiggle it.. and its not the uni's they are new...

althought the rx7 that my running gear came from had no vibration... there was no angle..
now that im running some angle on my uni's i think that is whats causing the play in the output shaft to slop around..

well thats my latest theory anyway...

im going to take the box out...
get the tailshaft tested elsewhere for balance.. get another gearbox and see how i go...

while its out ill see if i can improve the angle any furthur...

ill sort it out...
hopefully sooner rather than later

but ill get there
