Hi, Just about ready to order Avant Garde M550's. I'm looking at 8.5's in the front and 9.5 rear. The 9.5's are very concave, the 8.5's not so much. Just wondering if I should do the deep concave all round instead. Photoshop pic of the wheels on silver below. Thanks to Mod Bargains and the OP for the use of the pic. Thoughts...

Go with 9.5" all around. You prob will get a more aggressive offset that will sit better on the Z. Just go with two different width tires for front and back.

 

The offset is 20 with the 8.5 and 9.5. I was thinking of 11's out back, but I think that's too wide for stock suspension. No plans to lower or camber kit it, and I still want driveability. Any other suggestions if both should be concave, or just the rear?

 

You could go 9.5" front and 11" rear. There are guys that go with 11" width in the rear. But if you don't want to go that wide, go 9.5" all the way around. Choose a 245 or 255 width tire up front and a 275 or 285 tire in the rear.

I have 19x8.5 +11 offset in the front and 19x9.5 +17 offset in the rear. My front wheels sit nice and just about flush with the top of the fender. My rears are about 3-5mm tucked in the fender and not as flush as the fronts. Just to give you an idea of what your sizes and offsets may look like.

 

Go big or go home... get the 11's!

 

I have M310's in 9.5 front and 11 rear. Stretched @ 245/35F 275/35R Soon to stretch the rear a little more as well as the fronts The 11's give SOOOO MUCH more concave than the 9.5's. It's worth it, trust me, I did the same debate. If you are not wanting to go lower, I would recommend not stretching your tires though.. But why wouldn't you wanna go lower? o.O

 

I drive the car daily, even through most of the winter. As it is, sometimes I can feel the front end plowing snow, and the car floor riding on the snow. That's why I won't lower it. I've read 11's won't fit the inside suspension properly without camber, so that's why I was hesitant on the 11's. I was planning on the 245/275 combo, and don't want it stretched.
I think in the wheel info I've read, these 9.5's are pretty close to the same concave as the 11's in this brand. I just can't decide if all four should look concave, or just the rears. Damn. I hate these decisions!

 

Bro, I'm telling you lol. The concave from the 9.5 to the 11 is MUCH different. I daily my car as well, the 11's fit without any excessive camber, my rear camber is in spec..

 

On the M550 the 9.5/11 the concave is almost the same.

 

Go with the 9.5 deffinately! and a square 265 tire so you can even rotate. I had 255s on 10.5 front and rear and really liked the look.

 

You can go with Avant Garde M550 9.5 square set up, as far as the concavity of the 9.5 inch and 11inch barrel They are very similar. Pm me if you have any questions

 

Here is a picture of the 9.5 and 11's side by side for comparison

Double post

 

Would a 245 on 9.5 look stretched compared to the rear 275? Do these need hub rings? Thank you again Get Your Wheels and Mod Bargains for your helpful input!

 

Yes it would. I have a 245 on 8.5 & it has a little stretch.

I have the M550s from Get Your Wheels in 8.5 +20 & 9.5 +20 with 245/35 & 275/35. Thinking of going 255 & 285 next time.

No hub rings needed on 9.5 & 11, but required on the 8.5.

As for the 8.5 & 9.5, I like it kind of flat in the front & concave in the rear.

 

Thanks Strat, that's super helpful. Does that mean you wish you had the 11" rear also?
Any pics of your car?

 

I'll go get pics of 245/275 on a 9.5/11 setup.. Will edit this post when I get them.

 

I am running 9.5 +5 front W/ 245 and 11 +5 rear on a 275...running -5.5 camber in the back. I could easily stretch a 255 on the rear and bring the camber somewhere into the -3's. I dont think you will be happy with a 9.5 and having to run a super negative offset and possibly even spacers to get the right fitment. Its all in what you want to look like bro...Hope these pics and offsets help you out...

 

Nah, I'm happy with 9.5 out back. Pics to give you a rough idea of 8.5 & 9.5. Sorry, dirty car on a cold, rainy day.
