Some great information has come out in the last few pages.
We run on tarmac and use kits tires all round and I have struggled with over-steer at the start of the year. I spent some time softening the rear to try and control it and I did, but since then not really been happy with the corner grip my car is generating. Looks like I need to undo what I have done and start again.
My setup is the opposite of what everyone is using which may explain the lack of grip. If the over-steer returns, then I'll work on my driving or take a different approach. Maybe wider track, different toe. I notice most of the racers appear to run softer rear tires which we can't.
Currently have blue front springs and red rears and I had disconnected the rear ARB. I'll swap them front to rear, check my ride heights and see how it goes.
Thanks all!
