Wow yeah that's def where it's at, specially on street rubber.
Have new wheels with fresh rubber (same width & profile) fitted all round now. This should make a big diff straight up for me as my rears were fried b4 I got there Wednesday night. Had different width tyres front & rear which effects a GTR unless they're sized up perfectly profile wise to achieve matching tyre O.D. front to rear - which mine wern't Some believe this is not the case but for me you can see it straight away on the torque guage as soon as you give it a bootfull. In my case with the previous tyres the fronts kick in latter than they should when compared to say my track wheels/tyres which are the same all round. You can also see this on the vids Brendan got of me on launch as my rears would light up for a while before the fronts would intervene and pull her away.
Good times,
Wes
