cs tracking advice needed

went to a track day at imola yesterday (thread with pics in tracking section), and i determined that i need better tires. got lots of advice from all those down there, but what do you guys think?

also, i seemed to have some trouble with the gearbox whereby several times it just stopped moving up or down, no matter what i did, until i pitted and shut it down and restarted. some may be attributed to my poor initial driving habits, which i later rectified, but others were complaining of the same issue. it was a hot day and the car was runing pretty hot but within the normal tolerances. the mechanics on site explained that it may be that the liquid was leaking out too much in the electro valve, or that the pump was somehow deficient and not keeping sufficient pressure in the system. i found no leaks and when i dialed back my driving, the problem didnt seem to happen.

the "SLOW DOWN" light came on a few times, and i didnt know whether that was because we were getting too hot, or the gas in the tank had completely gone to one side and was reading too low, or because the gearbox was too hot. anybody?

as i (hopefully) get better at this, i suspect i will be looking for more power. however, at this time have no desire to get into a scud, so it seems to me that a couple solutions would be to put steel brakes on the cs, and look for more hp/torque somehow. the power to weight ratio of the scud is about 2.84, so we would need to find another 25-30 hp in the cs to match it, which seems possible. any ideas/comments?

 

i posted a duplicate of this in the tracking section if the mods want to delete this one.
