The TT sports a 4.6L 3V supercharged V8 pumps out 547 hp 463 ft/lbs of torque. Getting that power on the ground is Griggs’ specialty. The TT features their trademark SLA suspension, Koni coil-overs, heavy duty Torque-Arm, adjustable Watts link, and Griggs “4 on 4” competition brake system with ABS. The list of other race prep details are endless as is the options list. You can set the car up with extras for the interior, exterior, drive train and chassis to help mold the TT to fit your needs.
The TT can take up to 315/30ZR18 tires on all four corners without any fender modifications. With that big huge rubber, Griggs says the TT can achieve over 1.5 lateral Gs in the corners! The TT promises the best of track-day fun with streetable drivability. Imagine driving away at the end of the day, turning on the air conditioner and blasting the stereo.
You can build your own GR40 TT or send your 2005-2009 Mustang GT to Griggs and have them do it up complete with a serial number and pedigree. For more information visit http://www.gr40.com.
