Last Sunday I had a club race at the Erdferkel and finished the race in 6 best lap of 15.7 sec. The first 3 went best times around the 15 sec. My own gear ratio was 4.8 with a 104 main gear and 40 pinion.

I'm the only one TRF driver. That's why I ask here what else I can change to get ran the 15.0?

The Car drives very well but not fast enough. Hope you can give some tip.

One Option I Change the oel from the gear diff to Muchmore 5000 and a higher main gear.
