Ok this thing is significantly faster than the astina in a straight line. Managed to get to 160 on the back straight at qr today. Didn't get the chance to get any heat into the tyres unfortunately so the jury is still out on them. Loads of fun. Next month I'll see if it can be even faster ... without spending money.
Fwiw I could never keep up with an FT86. Today I could just edge away. Oh so close. Satisfying feeling
