Mid 80's GNXs

If those TA's were 12 second cars out of tge box the wimpy 7.5 rears tgey had under them are probably no longer original in mosy of them. How fast were the GN, high 13 at best I thought. </div></div>

Stock cold air GN should go 13.70s. Knock off half a second for GNX/TTA. In ideal conditions with the right driver... yeah, I wouldn't be shocked to see a Trans Am crack 12.99.
