Griggs Racing GR40ST on track at Infineon Raceway.

Customer Ken Ahmann comes along for a ride in the new Griggs Racing GR40ST Mustang with Colin Sebern behind the wheel. This car is equipped with the GR40ST suspension system and 4on4 Brake System from Griggs Racing as well as Jongbloed 18x10.5 wheels and 305mm Toyo R888s on all four corners. The GR40ST is a street legal full interior vehicle at 3420 empty and makes just 300HP.

Watch as we run down everything on the track including a 2009 BMW M3 during NASA TT at Infineon Raceway on 3/21/09.

All that traffic has got to be annoying!

A stock, decent condition, low-mileage GT will put you under $20k, the GR40TT auto-x and open track kit will run you 13.5k. And your still under Lotus prices with more hp. Sounds like a winner to me.

@JeremyGSU It was a N.A.S.A. event. The X on the back of a car indicates a NASA instructor. When they aren't instructing, they tend to go out and play in Group 4/TT, which we were in.

Either the other drivers couldnt drive - or this setup ist just amazing ;)

I had the opportunity to drive a stock Mustang. Value for money is good, but the suspension was pathetic. So this guy really needs to know what to do with cars to make them fast on a track !

Cool, I'm behind the wheel.

Not.
