Jeff, what data or knowledge are you basing your decision upon? Maybe Steggy would be able to add some definitive data to this question? I do like the sLK32 and it has but 78k miles coming up so it should have a lot of life in it if I don't abuse it. One fellow on this site runs in the 11's and his mods are not extreme. maybe it is Chuk?
