Yes Jon it does make a difference. My car is not stock in a number of ways, including weight distribution, so that qualification applies. But on the track with 275 lb springs all round, 22mm front anti sway bar, 20mm rear, 220 rwhp power down out of corners is significantly better. Just a touch of power oversteer to balance a touch of mid corner understeer, and the power can be applied much earlier. A few other things but that is the most noticeable, feels great, love it.
