I just got a black 07 Jeep GC SRT8 and am planning to install new wheels (GFG Nice 6) and other modifications. For the wheels, I need help on determining the size suitable for the car. (width= front and back - I think they have to be differant widths)

The sizes are as follows (taking a 22" but regarding size by width):
22x8
22x8.5
22x9
22x9.5
22x10
22x10.5
22x11

Also, has anyone tried the SRT-600 - SRT600 - 620 HP Turbo System Upgrade from Hennessey Performance? If so, please specify how it was. If not, please inform me of what you think about it and if I should install it or not

Please help, Thank You

Howdy. 1st of all, great choice in wheel companies! WTW makes outstanding products, with their GFG line being the best! I've had two sets of them and was always completely satisfied. Diko even made a special arrangement to get the first set of 24 inch Klessig 7s sent to me before their release date.

Anyhow-- on the Jeep, I went with 22 x 9.5 up front and 22 x 10.5 out back. 265/35 and 295/30. VERY happy with the fit.

The Hennessey package..... well, I think you're asking at the wrong place. Hennessey came onto this site a couple of months back, got in a pretty heated pissing match with a few folks who called him onto the carpet about his well documented issues with some customers, and it got ugly. Personally, after seeing his actions here, I'd never spend a penny with him.

His turbo does produce VERY impressive numbers though!

Congrats and welcome. Do a search on here regarding John Hennessey and you should dig up alot of info. As far as the wheels go, I would say Ge2 is the man to ask about tires and rims.

I guess if you are going to spend $7,000 on wheels you can afford to buy his turbo kit. You can probably afford to buy a new hood, engine, ect... whatever else he can sell also. :D John H builds amazing cars but you have to be lucky to not have a problem with him.

welcome to the site... we have this thing around here that newbies have to post a pic of there wifes... so far Ge2 is winning with the hottest one... so when ya get around to it post her on up

LOL that's funny

ge2, post another picture so we can compare yours and his:p ... didn't you say you had bikini pictures or something like that?

LoL. thanks for the help everyone... Still not married so the wife thing is not gonna work :) However thanks for all your help, I'm surely going with these wheels and I'll post a pic of my GC SRT8 as soon as i get them on
