I have no clue raceram, we were at capital raceway. was a few new ram's there, best run that I seen was 15.2. My friend ran 4 time's 15.3, 15.3 15.4 and a 15.5, Maybe if it was cooler out he could gain alil bit I'm sure or at a different track. I love the new design of them They look great and I am not bashing on anything just my opinion that's all, As far as being fast as a stock lighting I can find that out very fast. He also got trommped on by our friend's silverado ss. And I romp on him all day long. ss is a low 15's truck awd or the 2wd. ss trailblazer was 14's but more HP.
