i've raced my friends bone stock gts as i am now and another one with and i've beaten both with ease. my friend's is a 6 spd. the key to drivin them is to skip a gear or too, they're geared close and have high redlines. if you shift at red line you only get knocked down to like 6500 and the vvtli kicks in at 5, skip a gear and drop it to 5k rpms and then you can run the 14.9's. my friend runs through every gear and i smoke his ass. he raced my other friend with a bone stock rs and the gts just barely edges out the stock rs (5spd)
