I'm not sure of the difference, just had a newer looking one at the gas station peel out of the parking lot the other day and I was curious of what to expect if I came across one. Also on the BMW subject, how do the 135's do? There's a kid I know that just got an 08 and said he's doing some mods but wouldn't say which ones, then wants a race. I expect to beat him but not positive.
135's are pretty stout little cars.. With that being said most of the "Full bolt-on" 135's seem to run low-mid 12's trapping mid teens. Seems like the 11 second cars are further modified with meth etc. I think their turbo's max out around the ~480whp mark, then again I am by no means an expert on 135's. I can tell you that most of the 135/335 community think that their cars are rockets that can't be beaten once they tune them. So to circle back to your question it'll come down to your car/mod/your driving... ya know the "normal" stuff haha
