2011's
GTFO. The GrandSport kicked the crap out of both cars at the track and the '11 GS was even better. THe Porsche won because of C/D's normal bias towards steering feel and interiors. Don't make things up.
I don't think the fenders make much of a difference. The Corvette is wide car in any form. Learn how to drive one and it really doesn't matter.
Per specs on the Chevrolet website the differences in weight between the Corvette and Corvette GS in 4LT are as follows:
Corvette coupe GS---3311
Corvette coupe-------3208
103 lbs. diff
Corvette conv GS----3289
Corvette conv--------3221
68 lbs. diff
The GS's are way cool thats why I ordered one and have a 10/19 appointment at NCM.
