Spoke to Pito. The Car is going back soon with improvements. With an easy 1mph more and low 12s. The suspension already got changed and the tune modified since the car was running a/f ratios of 12:5 and 12:1 on 4th gear and problems with the rev limits...and it got a new alignment.
About the clutch its a bronze act with one year of hard use and when it was reassembled it didn't get resurfaced so there the effects. We'll see how it behaves and with slicks.
