Offset for 19x11 Wheels

[Jabooh1]

Looking at adding new wheels to my '13 LS. Going with 19x11 in the rear and wanting to get a 305/35 on them. I like the was the stock rims/tires line up. From what I can tell they are 19x10 +47.5. If I use the offset calculator at 1010tires.com to keep the same outside edge it needs to be 19x11 +60. That means I add the 1" wider rim toward the frame/shocks.

What offset do you guys who have 11 on the rear run? I was thinking +55-57. Kinda worried the 60 will hit something.

Thanks!

Awesome thanks!! It is so hard to find offset info because most people don't know or care.

Does the tire stick out at all? Do you know how much clearance you have on the inside to the shock, frame, etc.?

On this current set up im running 305/30/20 with no rubbing issues at all, and as you can see the car is lowered pretty low.
On my last set up (2012 GT) I had FRPP K spring with a 315/35/20 nitro invo and clearance was great, no rubbing, no bottoming out.
This is all with the same wheels
This is what it looks like with that offset on 315/35 and k springs

My 19s are 33 offset in the front and 53 in the rear, Forgestar CF5Vs, 19X9 F and 19X11 R. I should have pics on the car shortly. Running a M/T ET Street 2 305/35/19 on the rear.

 

[Jabooh1]

Great. I think I have settled on the 19x9 and 19x11 Forgestar CF5V in gunmetal with +33F and +53R. Found a pic of F14's on a grabber blue and looks good.

would offset still be the same no matter if you went with a 9 or a 9.5 up front? wish this info would have been posted up 2 months ago so i could be rocking 11 inch wheels in the back!!

 

[Jabooh1]

No. The offset for the front is more like 33 (flush). Stock LS wheels (19x9) have a +42 offset. It simply moves the wheel 9 mm outside.

The offset is simply the distance between the centerline of the rim to the mounting face. So a offset of X on a 9 is not the same as on a 11.

Poof100,

Did you get yours mounted? Waiting to order till I see your fitup.

My nephew has Vossen 20x11 on rear with 305/35 and he does have very minimal contact with outside lip under hard acceleration, I do not know offset, sorry. I have 19x11 Forgeline on my Boss with 295/35, but I would have no problem running 305's on mine, you can definitely see there is a big difference in offset between mine and his GT. do not know the offset on mine either, just call Forgeline, those guys are great.

Poof100,

Sorry, no pics yet. We should have some pics some time this week. We have been more focused on getting the car on the Dyno this week to tune it for E85 in prep for the American Muscle Dyno shootout at the AM show next weekend.

I'm running my own design of Seven Forged wheels 19x10 up front +40 and a 19x11 +55 in the rear. Nothing hitting or rubbing. You will need a pan hard bar or watts link to adjust the rear. I'm running 285 front and 305 rears.

The wheels are also true forged 1 piece Monoblock 21lbs front and 23lbs rear.

Here a few pics of my set up (Cortex suspension waiting to installed)

Just placed an order of the CF5V Goss Gunmetal 19x9 +33 and 19x11 +53! Now off to select the tire. Thinking Nitto Invo 255/40 and 305/30.

 

[fast4v]

Great offset!! Does nitto have a 305/30/19?

They do. About $300. Either nitto, hankook ventus v12, Bridgestone potenza s-04.

Here is a quick pic of one of the 19" CF5V wheels in Textured Matte Black on my White Boss:

Looks nice! I bet you are ready to have it all done.

Anyone run a 325/30R19 on an 11" before? The Nitto website said 11" is the minimum rim width for the 325. Don't know if I should order those or a 305 first.

Thanks, I think they came out pretty nice. Although, I think the Gun Metal/Silver would look killer on a White car as well.

Car is almost done, it's running right now and goes on the Dyno tomorrow! :banana:
