Bmw Schnitzer TT-01 Speed Gears help...

[Eurocupracing]

When I was looking around for hop up parts for my Bimmer I ran into a problem..

I want a faster speed from it so.. I want to know what the best combo of gears is that everybody calls the best?

The stock gears are a  61T Spur Gear  and 19T pinion. I know that you cant use any other pinion than 22T?

So... What pinion do I use with the 55/58T Spur gear set? And whats gonna give me the best Performance?

Ive got a 13 turn motor right now and a 3500mah battery just so you guys know.

Thanks Much!
