Ok, it seems to be generally accepted that the Prelude Type-S is the fastest Prelude ever produced. But I was wondering, wouldn't the Prelude SiR be faster, both 0-60 and quarter mile-wise? It has the same 220ps motor as the Type-S, but employs an LSD instead of the Type-S's ATTS. So I'm thinking it would get better traction at the start and accelerate a little faster due to the Type-S being a bit heavier because of the ATTS system. Anybody have any times for either of these cars? Or am I way off track here?
