Both trucks?? Corr class is Corr class. Modified only changes with certain upgrades to the truck. I think the largest field in any SCT event would be a stock class to begin with dont you. But a modified corr truck is cool too. Like Kyles loaned Slash at the Slash Bash was cooking running a Wild Child modified motor.. ALso the SC10 would be more of a handfull to drive with a mad modified motor. There are people complaining they cant get around the track with it stock. Keep it slow, and competive I say. BTW, the 17.5 is no slower on the layout than the modified T4's fyi. Are you coming down saturday? Who's in for saturday? More the merrier.
