It seems that some SS/TCs are running as low as 13.5 in the quarter mile...STOCK. Mid to high 12s with basic bolt-ons. I have not driven or raced an SS/TC, but these cars look fassstt on youtube. My question is- why are they so much faster than Speed3s? Does 200 lbs make that big of a difference? They have 2.0l with Ko4 turbo. Any insight would be helpful.
