Trackday at Mantorp - test of slicks

A very hot day at Mantorp Park again - with slicks for my first time!

The lap times where not that much better, only about a second. A bit disappointed actually. But probably it is my driving to blame, I'm (yet) not capable to take advantage on the extra grip! I felt the biggest difference in one of the high speed corners (the fast left before the hairpin), where I now could keep the pedal floored - when I dared!



Today's Best: 1:26.9
Most laps where constantly around  ~1:27.5
Previous all time best with ACB10: 1:27.9

The day that started with oversteer problems, especially when trailbraking into corners. Reduced when lowered rear pressure to 18.5 psi. A contributing factor could have been the new front discs and pads messing up my brake balance. Overall the car balance was good - I just need to learn how to drive faster!

Avon 15" ACB0 crossply slicks (see previous post)
Front: 19 psi
Rear: 18.5 psi

At the end of the day the engine started to sound loud! The reason was a cracked exhaust manifold. I left the car for the tech guys at Mantorp Park and hopefully they'll be able to weld it together in situ. The manifold cracked most likely because the rear silencer bracket went loose, again, which caused stress on the manifold.
