I have a rs4 rally converted in to an on-road racer.
so far this is what i have done to it.

Bumper from the pro2
front upper sus. from the pro 2
rrp topshaft.
and 2degree kick up.
and lowered
soarex tires and yokomo rims
200mm porche 911 hpi body

so far my car weights 3pounds exactly with battery and body on. i know that the stock version of the rally is more about 1/2 lbs more. I was just wondering since off road is diff from on road what should i have my motor geared for a p2k and a 17x2 mot. The track is got a long strait away and just a couple tight turns.
what do you guys reccomend I gear my car? Dont forget the rrp topshaft. (lighter and more precise than stock topshaft)

Thanks in advance to anyone who can answer my question.

Experament. If you can, borrow some gears from someone and try 'em out. If not, then make a ballpark guess and go from there.

When I used to race my RS4 Pro with a stock motor I would use about a 37-38 tooth pinion and 116 tooth spur. I was running on a large track though. I'd say try a 35 with a 116 to start with.
