impala SS, Monte SS, GXP
i had a GXP but i traded it for my TA. their is a guy running in the 12s i belive with a nitrous shot the aftermarket is still gowing for it it isnt full blast yet. so far the GXP have all gotten the faster times. the impala/monte all seem to be in high 13 low 14 range with most of the Grand prixs stayin in the high 13 range.
