My 2010 is not the heaviest vehicle I've ever raced but it's the second heaviest.
My now-sold 2006 TBSS 1SS RWD was heavier. I did get that tank to run 13.84 stock and 13.73 with a cold air.
I got my last 4th gen down to 3300 raceweight with a stock k-member and front end. Full weight raceweights for the 4th gens ranged from 3590 to 3800.
I haven't weighed my car but I'll assume somewhere around 4150 with me in it (I'm 200). I'd like to get to 3800 raceweight, so at some point I'll play with skinnies.
My 2nd 4th gen (this one got the most changes over 10 years)
