Also, are you running those heights w/ stock t bars?

My car started started doing the same. Turned out to be a bad driver side front wheel bearing.

Yes Im running 19 up front and (85 carrerra 3.2 in the rear - I think 24? - I wrote it down when I installed them, cant seem to locate that sticky...)

All wheel bearings have been checked, here in NZ we have a very strict WOF (warrent of fitness) for all vehicles every 6 months, mine just passed last week and one of the main checks is they jack up each corner and check all the ball joints and wheel bearings. Im really leaning to the new rear tyres as the main cause, as they seem to have so much side movement, also the tread looks cool, but it could be the cause, all it has is deep swooping grooves from the center to the outside.

The way the car rides in a straight line is fine thu road imperfections with both hands (10 and 2) its only if you turn the wheel like 1/2 inch or more and the car will initiate a turn,
the weight transfer is obvious on the rear and then the car swerves, If I understand the toe in on the rear, this helps point the nose in the right direction?
or is it toe out that would do this? some one mentioned the toe in is only for braking stability.

I think I'll have a play with the rear toe in/out and road test it to get a baseline of what makes it better/worse.

Thanks for all the tips!

Ok after trying different rear toe settings, raising ride height, putting F1 205's on front to match the rear, nothign fixed the issue.

As a last resort I tried a used set of tyres on the rear and the issue was gone!

So I changed all the tyres to (Dunlop ZR225/50/16 rear and ZR205/55/16 front - Direzza DZ101's all round)

Now it handles like its on rails! Awesome and stable at high speed.

Thanks again for all your input!
