Actually take them off the car and check them on a piece of glass. They may look straight, even if they're not.

will have a look and let u know later see if they are bent
sumits obviosly bent if the tweak is spot on etc and still does it just finding what it is. basically with the slightest bit of throttle round a right bend it 180's. and it aint me i aint winning 3 local championships for note.

3 degree toein both sides on rear on the dot so if it is sumit bent cant be on rear its got to be front.
diffs feel really smooth and dont slip.

just trying to sus it out now

You say that the tweak is spot-on, but what is the difference between the shock collars left to right,front and rear? If they are more than 1.5mm out then there is tweak in the car somewhere and here is your problem.
Also I find the top shock mouting screws can bend easy.

Have you tried my suggestion of leaving out screws from the top deck two at a time from the front, moving back?

Something is twisting the chassis badly. Could even be a bent bulkhead...

I would strip the car to the bare kit peices.

Put the lower deck on a very flat surface and each time you add a part check to see if the chassis tweaks. if there is not tweak throughout the build then it HAS to be something to do with the drivetrain. Make sure your diff pulleys are shimmed correctly and not rubbing on the bulhead or shock tower. I once had it where i shimmed to pulley too tight and it did a similar thing. You can usually tell if it is too tight because it is a bitch to put the top half of the bulkhead over the plastic cams.

other than than, check all the driveshafts are working properly,check all bearings are working check wheels are not rubbing anywhere, you have take into account that if something is close to rubbing, when you go round a corner, things move with the weight transfer. Wheels move quite alot also.

Im sorry I haven't read all your posts but maybe the problem isn't tweak at all. I once had a bearing(hub) that was bad and it only showed when I tightened down on the wheel nuts. They somehow caused it to bind up and make the car feel like it was 3 wheel drive.

Could even be a broken CVD pin. They're another problem part along with the hinge pins.

Default Hinge pins

You probably already did this...but did you check the outer and inner hinge pins.

Actually roll them on a flat surface..
I've had the same problem before...i had to take the car apart a few times..to find it..
a few times the hinge pins
1x found the ball cup was pinching the ball stud.
1x used long cvds found they were binding against the diff keeping the car from having the correct roll.

You'll find the problem, it's probably something small.
Good luck
