question about rims and tires

Hi, recently I was thinking about upgrade my rims and tires of my 2011 gt500. It has the SVT package. So that's the specs I have read in someone's thread.

front:20×9.5 et29 with 275/35R20 ps4
rear: 20×11 et56 with 325/30R20 cup2

Will these fit my gt500?
Will the rear tires scartch the rear fenders.?
Is it necessary to modify the rear bump stop to prevent rubbing on the inside when suspension is unloaded？

Also I'm gonna tune the front camber to -2 degrees. In this case do I need to change the offset of front rims?

What brand /type wheels are they? Rubbing issues/fitment depend on many factors. Type and curve of the face of the wheel, suspension mods, height of your car, etc. There are very limited wheels for our cars unfortunately. That's why you'll see a lot of the same wheels on these cars. Short of having custom wheels made, you'll have to be creative.

I have 18x11, 315 on the rear, but my bumpstops were already removed when I bought the car. Former owner was running 345 on the rear, so I can't comment on that.

Yes as long as youre not running sportlines or sit really low. They will poke some but not terribly bad.

I also own a gen2 cts-v and a gen3 dodge viper.

Those must be crazy exotic in China.

I was in Beijing and saw a basic v6 mustang draw a crowd like nothing I have ever seen.

Off topic, but what fuel options are available in China?

Actually yes, it will be an issue. Ive run into this problem before with a stock shelby. The inner side of the tire will hit the bumpstop bracket. On a lowered car, the bracket sits below the rim, guaranteed. You can do bumpstop relocation though. You may also need an adjustable panhard bar but thats a maybe. Even bone stock gt500s have had the axle be too far to one side of the car, but its noticeable with stock wheels/tires. With wide wheels and fat tires it will be noticeable and may put you more at risk of rubbing.

If youre going to run this set up either:

1. Lower the car some

2. Bumpstop bracket relocation

3. You may need an adj panhard bar but you can wait till the wheels are on first to see

But the 98 maybe equals the 91 of US.

Ya, Ive seen first hand what effect fuel from over there has on aircraft fuel systems. Jesus, and I thought e85 was dirty

And here I thought china had some kind of advanced refining capability not available in the US. The 90 must be like US diesel.

That Viper is badass my friend. That's going to be my next purchase, but my wife made recently get the new Telluride because she wants to feel like a soccer mom although we don't have kids.

On a side note, I've been all over the world, and I'm always amazed by people in other countries and their ability to communicate. When I went to Japan a few times, most of the people I met spoke 4 to 5 languages including English, and these were college age kids.
