A 9.5" +12 will require front camber around a -2.3~-2.5 depending on your tire choice. It looks good and will give you a great turn in response but at the cost of camber/tire wear.

shoot, i drive a lot. around 600-800 miles a week so that will eat up tires like crazy. i really wanted to go with that set up. im still running the stock tire sizes as well. what if i went to a 235/35 19 instead of the 245/40

One last shot (just in case)...
 

I had another thread, but I wanted to devote this question here since it's related to 275 tires up front. Apparently Hankook does not offer 265/35 tires, so I wonder how feasible 275/35 tires would work if I were to get Swift lowering springs.

The front wheels are 19x10.5" +40mm with a 10mm spacer to clear the calipers. Current tires are 255/35.

I would like to have a setup like this : 20X10 at the front and 21X12 at the rear, is this possible?

I am currently running this setup and it is very possible! Let me know how aggressive you want an I can work up a quote. We have a crazy deal going on for Strasse wheels!

I am running 20's all around though.

Doing big things, Ordered my wheels today not going to say which ones or colors, but I say say this I am going to powder coat them and the sizes are 19x 10.5 + 12 all around ;) oh yes!!!!

how will these work out on my non sport

front: 20x8.5 20 offset tires - 255/30/20

rear: 20x10 25 offset tires - 285/30/20

Here's the setup I just bought. (From a previous vehicle, obviously not the right offsets for a 370)

Front: 19x9.5 +17 - RE050A 255/35/19
Rear: 19x10.5 +18 - RE050A 285/30/19


I know it's not going to look right as is, so what do you think would be the recommended spacers needed?

Currently looking at a 10mm in the rear, also going to pick up some universal 2.5mm ones in the event 10 isn't enough. I've also been told 15mm's would be too much by someone having the same offsets. Anyone else have an opinion in this?

10-15 should be about right for the rear. Your plan sounds like a good call.

Yup, if you get a 10mm spacer for the back, you'll be at +8 offset. That will be plenty aggressive with a bit of camber (-1.6 to -2.0).

The front may be a tad aggressive. With a 9.5 diameter, +22 to +25 would be good with a bit of camber.

Are you lowered?

crazier the offset the better.

I will be putting on K&W V3's the same day, so yes I will be lowered when these go on. I currently have a rear camber arm installed, need to get the front but damn they are expensive lol

20x8.5 front and 20x10 rear....+25 offset comments/suggestions?

Wheels TE37SL

front 18*10.5 +15
rear 18*11 +18 with 5mm spacer
