Mugen10,
For carpet rubber tyre the car is excellent. I quess at your hometrack most guys run foam tyres? As foam is not very populair worldwide, Tamiya made the 416 for rubber tyre racing, the car performance not so bad with foams, it only needs little stiffer chassis.
IQ0,
At that time I ran 5 cell 3.5, gearing about 8.6
Power program 4 on the nosram with 1 autobrake and 1 initial brake.
This was still the old version speedo, on the new I should go for 5 or 6 and autobrake 2.
