1999 Trans Am Front Right View
On the next track day, we brought the T/A down to see if it could improve on the 13.45 average elapsed time recorded in stock form. Although the weather conditions weren't as favorable as they were during the baseline testing (see "Track Testing"), the T/A was able to eek out a 13.38 ET best, with almost 104 mph on a previous run. That gain was nearly 1 mph in hotter conditions, and best of all, no adverse drivability issues have been seen on the Pontiac.
