20"s on a 2007 Mustang GT Do and Dont's Any Suggestions?

I have an 07 GT thinking of getting 20x9 razors with Eibach lowering kit, anyone have this setup? If so had any issue or any tire suggestions.

20 x 8.5 is a popular size, can go as wide as 255., would be 255/35 to maintain diameter of stock (assuming you have 17x8's with 235/55 17 on now), with a 9 inch wheel you cant go too much wider( some will disagree but i'm going by 1010 tire size calculatohttp://www.1010tires.com/TireSizeCalculator.aspr)..275 width is recommended for 9.5 min width.. heres the link, its a pretty cool tool..gd luck, i've always liked the razors...

I finally got it done. I ended up going with a Eibach Pro lowering kit, 20X9 Shelby razors with Kumo tires 245/40ZR20 in front and 285/40ZR20 in the rear. Looks freaking awesome to me. No problems with anything, took a little bit for the dealer to get the TPMS system to reset for the tire pressure and size but everything is fine. Thanks for the info. Some pics are on my profile.

really like that colour combo between the wheels and the white..don't think it could look any better..I have a set of 20's (BOSS 328's in black chrome) waiting to go on in spring, also going with the prokit, just want an honest opinion on the ride quality with 20's and prokit.. did you put a panhard bar on, and did you need a camber kit...thanks in advance, your ride looks great!!

No, they only thing that went on the car was the Eibach Pro lowering kit with those rims and tires. The only problem I am having is that the back tires stick out a little. The dealer that installed them has ordered a different backspacing for the rear. Hopefully those rims will work with no problem. Just make sure you order the right ones the first time. I found out if I hadn't let him order the rims and stuff since he picked the tire sizes and rim settings he has to fix it. If I had ordered them on my own once they are mounted to the tires they are non returnable by almost any rim company. As for ride quality I have only drove it about 25miles since I put them on. I didn't notice much difference to be honest, but I have only drove it on the expressway.

Just wanted to give a little better info in case someone come across this thread. I am running 275/35ZR20 rear and 255/40ZR20 in front. Didn't post correct sizes on first thread. Am probably going to switch to a 255/35 in front because I would like to have a little more room in front to prevent rubbing if I was ever to have a full suspension compression in front from a bump or extreme turn.
