Can someone please verify these offsets for me?
 

I have ordered a set of 19x9.5 and 19x10.5 TSW Nurburgring wheels. I want them to set close to how the factory wheels do. I have a touring sport with the bigger brakes. Can someone confirm these offsets for me? The more I read the more I worry I may have ordered the wrong ones.

Front +20
rear + 27

If I calculated right, with these widths and offsets, the front will poke out about 33mm more than the stock sport rays. You will gain inside suspension clearance by abt 21mm

The rears will have about 3mm less inside clearance to suspension parts and will be about 9mm further inside the rear fender.

Hope someone can verify this for you also.

So if I want the fronts to fit like the factory I need to go with a higher offset? Lower for the rears if I don't want them to tuck more? Someone want to suggest what offset to get?

I mistyped the info on the rear wheel. It is 3mm less inside clearance and 9mm of addition poke closer to the fender.

Right, higher offset for front will bring it closer to factory fitment.

Since these wheels are half an inch wider, I would suggest that a 19x9.5 +40 and a 19x10.5 +23 would be the closest fit to stock. This will leave the inside clearances within 1mm of stock and they would both poke out about 13mm, front and rear wheels.

Very good. It seems a lot of people are running 19x9.5 / 19x10.5 with +22 / +12. should I go that route instead?

I am almost rubbing on 9.5" with 35mm offset, not sure how you can go 22 on a 9.5" rim

from wat AZ posted he metioned that there is PLENTY of caliper clearance for the front because the spokes are rather flat and discs are pretty thick.

from a caliper clearance i think you're fine. you'll probably want to run 15mm spacers in the back to match the front's wide stance and lower your ride to tuck the top. at ET22 and 9.5" without drop the tires will appear somewat pushed out.

Stock Rays wheels are 19x9 +47 front and 19x10 +30 rear. If you want aftermarket 19x9.5 front and 19x10.5 rear to fit EXACTLY the same as stock, you need +53 mm offset front and +36 mm rear. I wouldn't recommend this for two main reasons:
1) you may have caliper clearance issues, depending on the spoke design, so if you can get a template from the wheel manufacturer to measure first to see if they will clear your setup before you buy (This is as simple as downloading a PDF file that gives the cross section shape of the wheel, print and cut it out, and then place it against the hub assembly to see if the brakes clear).
2) Most people don't like the somewhat "tucked" look and run 15/20 mm front and 20/25 mm rear spacers...that depends on how close to fender edge you want.

Most people will run 9.5 width +22 front and 10.5 width +12 rear (in either a 19 or 20" wheel) and that will get you fairly flush to the fenders if the car is slightly lowered. Other factors will play into it too...eg whether or not you're lowered, tire width, and negative camber you want to run. Some people want to push the "flush" envelope have gone with more aggressive offsets.

Thanks for the insight. I think I am going to change to a +32 front and a +20 rear.

That would be perfect for stock height. :)

Use this Offset calculator for help...

plug in your current widths and offsets and what you want to switch to and it will show you what will change! Pretty cool :)


Your current set-up is... 19x9 +47 front and 19x10 +30 rear
