Mine is the bassic CF. 2004. The rear tires are the stock Contis. I just replaced the fronts with the very sticky Dunlop Z1 starspeck. Please, no sermons on different front and rears. I bought the new stickies, of course, to reduce understeer. I'm sure it will, but if it still understeers excessively I can experiment with F@R pressures and the camber bolts(which I have).
I was affraid of getting conflicting views on the pressures but it was worth a try. Thanks for the replies.
