Here is an attempt at the GT lap record at Harris Hill Raceway (San Marcos, Texas) in a newly-built Howe Trans Am TA2 Camaro. Derek Eastty is the driver. Existing record 1:14.8 was set in September 2013 by Max Papis in the #61 Grand AM AIM Motorsport Racing Ferrari 458 (GT3). As you can see, Eastty just misses breaking the record with a 1:15.37, and he says he'll be back after a little suspension tuning (Harris Hill is a rather bumpy track which rewards different settings than normal).
