Re: 1996 STCC [Closed, except if waiting for approval]
I also get really twitchy if not using the minimum possible margin to the limits so I ended up tweaking the rear overhang of the frame until to got the weight exactly right it actually makes very little difference (like 0.01s tops).
Finally, I didn't like using such tiny wheels in such huge wheel wells... But the lap times were best with 15" (and unsprung weight reduced too) so there you have it!
