Speedjunkie:
Get rid of toe in up front. That’s killing your front end. Secondly those mushy tires are something I would address after that. If you’re after response you’re going to want something with a stiff sidewall.

Your traction rod should be extended the same amount your camber arm is.

You may want to consider extending your lower control arms, this helps with understeer quite a lot.

I think those changes alone will make the car wildly better to drive, but if you’re still having issues with bumpsteer then you need to take the time to measure it. You’ll have to test different tie rod heights yourself, I don’t think anyone has done that with the gktech grip knuckle.
