No Rob, I don't race any of the cars you are saying have a built in advantage. If thats how you think then you are beat before you even get off the truck. I have built many nissans and raced against many acura's and honda's. The reson the development has gone so well on those cars is their was lots of folks doing them. Th e ITA 240sx was not a real popular piece until Stretch spend the time and money to develop one and prove it could win. Sorry but I did read the whole thread which started out as a thread about rings and that's part of the response you got from me.
