So was this a bone stock Mustang GT and just added the GR40ST suspension or was it an actual GR40ST 'turn-key' car with 368 HP? I have a blown '08 Mustang (450 rwhp) and my dad has a C6 Z06 and I just don't see a 300 HP Mustang getting even close in the twisties even if it has those Griggs components. The Corvette drivers MUST have been somewhat conservative for one reason or another (afraid of oversteer???).

@Feshdogg

This Mustang has 305HP (dynoed). You have to understand that the Griggs setup replaces the stocks suspension, not just bolting on better components in the stock locations. Different geometry and pickup points. The car is converted to a SLA front suspension for example, similar to a Corvette. So while it LOOKS like a Mustang the underside is completely different, making it very easy to catch Corvettes, Porsches, etc.

@GR40Freak So is that 305 FWHP (estimated) or RWHP?

[GR40Freak]

@Feshdogg 305RWHP and the best part... 3900lbs at the time of time of the video. Car weighs 3400lbs. with 1/2 tank. I weigh 300lbs alone. passenger in the video weighs about 180lbs. and the car had a full tank.

@GR40Freak

Im a little confused about the weight of this vehicle. I found another video of this car saying that it weighed 3420 (no driver). Stock gt weighs 3575. Does this suspension, brakes, wheels, and tires alone really remove 155 lbs?

[GR40Freak]

@sdghjsdf

The weight savings with brakes, wheels, and suspension can actually be over 200lbs. it depends on the car and options. I keep doing things to my car. It currently weighs 3395lbs. full of fuel without driver.

Nice driving and I bet that suspension is awesome! I have a $25,000 C5Z corvette with 365 rwhp and I'm just an occasional hpde guy, but I run 1:58-1:59 laps at T-hill in the same configuration as this video (I have videos posted here). So although you were faster than the drivers of those vettes I don't think it's representative of all C6Z drivers with 550 hp ;). However, I always enjoy watching your vids.

The Vette driver either doesn't want to ball up his car, or (s)he's a new driver doing what he's (s)he' suppose to do, taking it easy until he learns.

a skilled driver is going to beat a newbe in just about anything.

@GR40Freak Any new activity in GR land? I've been watching all I could of you GR guys. I'm wondering if any testing or new development with the new coyote mustang platform is being pursued. The Boss 302 looks mean, but with the GR SLA suspension on one, it would become godly. I would LOVE to see you guys get your hands on a Boss 302 and do your magic with it, and show how it's done! Hell, I think Ford ought to absorb your expertise into their performance division, if you know what I mean.

i just went throught the rest of the posts. what a bunch of sore losers you corvette lovers are. i bet half of you dont even own corvettes and your crying. this car has full racing suspension and griggs has been knows for YEARS for its incredible suspension. I saw a video of a cobra pulling a 1.5g lateral on a hill climb with griggs suspension... the zr1 doesnt even pull that kind of g through turns. now thats something to cry about. sorry I dont have anymore tissues.

I believe this video is trying to show that even though the Z06 had the power advantage, the gr40 GT was able to carry its speed through the corners. It shows that with the right equipment and an experienced driver, one can be fairly competitive with the big boys.

[wbceditor]

Great showing. High five to maintaining cornering speeds!

[ZR1Terror]

add some suspension upgrades on the Z06 and you won't see it's dust!!
