Quick update, fitted some new Enkei wheels pf01s, had it back on the dyno and found some more mid range. And used the Hans for the first time last weekend at the AASA / Modern Sports Car weekend.
Strange weekend, track was cold and then very very wet. Managed to almost equal my best time with a 1.12.16. Definitely more in it yet, need to get an 11 in front

Pics and vid to come soon!
(Anyone have a single or even pair of 15x8 6uls they want to sell.....?)
