02 Gt or 02 Z28..that is the question.

Here are some issues durability wise to look at...

LS1
*Weak rear end.
*Weak clutch (99-00's can barely handle drag radials without slipping, get an A4).
*Miss a gear or over rev and bend a push rod.

4.6
*Weak trans.
*Weak IRS(Cobra only) (Couldn't handle very much abuse at the track).
*Throw out bearing was a problem on the 99/00's, seems to be fixed on 01's.
*Carrier bearings in the rear end fail quick on the 99-00's.
