RE: rb or vspec
well i guess in reply to my first question and i guess from what supertib described a jpx sounds like what i need, the track i'm running doesn't have a significant straightaways, definitely not 250 feet and there are a lot of twistys to jumps, i may be going with a jpx, i'm not sure still but from what he says, its what i'm looking for is there a mod thatll make it a little more linear? i dunno this seems to be my biggest speedbump thus far, how many gallons are the jpx's getting?
