1" wheel spacers on all 4s (pics)

[BlackGT]

I am excited about it but had a hard time letting loose of the money! Once I did it, I felt much better and now I am just waiting on it to come in.

I went to the track last Friday, saw a guy there with one on his 15, it was screaming

Maybe the lowering adds some camber and tips the top of the tires in almost all of that 3/8" poke the OP is getting. Your car looks much better, even though I love the 20s.

No, rear camber is at -2.0 on a spec of 0 to -3.0. The wheels themselves to not stick out past the fenders, neither do the tread of the tires. In the rear, where the sidewall bulges out, that sticks out from the fender just slightly but the tread doesn't. The front is completely inside the fender.

I'll have pics on Wednesday. Getting dropped on an Eibach Pro kit along with the spacers.

If you happen to do the spacers first, please post some photos with the stock springs!

Also, would someone please post a close-up pic of the hub area? I'd like to see what the spacer looks like in there.

My wheels do stick out just a tad more than I would like but the 20" wheels have a slightly different offset to the 18s and 19s from what I understand.

You are correct regarding the front, but I think on the rear the GT PP 9.5 inch wheel actually comes out further. Here's the theory:

Both the front 19" and your 20" factory wheels are 9 inch wide but the 19"s have ET45, whereas your 20"s have ET 42.5. This means that the wheels themselves come out 2.5 mm further than the 19"s. Also the tire on the 20" is 265 instead of 255, which means it is 5 mm wider both on the inside as well as on the outside. The nett result is that with the same spacers the 20" will come 2.5 + 5 = 7.5 mm further out.

In the rear the stock PP GT wheels are 9.5 inch wide with ET 52.5. This gives as a net result that the 20" wheel will sit 1 mm further outward than the GT PP 19" wheel. The PP GT rear tires however are 275 instead of your 265's on the 20", which means 5 mm more outward. Combined the 20" with the same spacer should sit -1 + 5 = 4 mm deeper than the 19".

Please help me with my math here. JBailer's EBM looks great with the 25mm spacers. I want to copy the fitment.

However, I am going to change tire size from 255 to 285/35/19. The additional bulge of the tire on the rim will change the spacer size I'd need. So, 285-255= 30mm /2= 15mm additional tire bulge on each side of the wheel. So if my logic is correct I'd need a: 25mm - 15mm= 10mm spacer

Does that seem about right?
What size is the hub?
(So I can find the proper hubcentric spacer)

I use this tire size comparison
http://tire-size-conversion.com/tire-size-calculator/

If your stock tire is 255/40/19 compared to a 285/35/19, You'd be going from tread width of 10.04" to 11.22. a difference of 1.18" or 29.972mm /2 (because half on each side of the hub) = 15mm difference so you're correct and want a 10mm spacer if my figuring was right. :cheers:

That looks great and very aggressive with those sportlines!

Great info. I am going to go measure at the dealership this weekend but I think from what I've seen, and based on this excellent info, that I'm probably going to get the Eibach 20mm for the rear and the 25mm for the front.

Wow that looks great, and you did it without changing rims!

Did you guys get a lower profile lugnut with your spacers for the interior studs?

Would have thought they would have been included. Also my spacers came with a different thread on the exterior lugs. Why not use the same thread? Maybe I got sent the wrong ones.

You probably received spacers meant for the 1994-2014 models. These (and those cars as well) have a different thread.

You can use them but you will need 10 new lug nuts per wheel. 5 low profile ones with 2015 thread to bolt the spacers to the car and 5 regular ones with 1994-2014 thread to mount the wheel to the spacer's studs.

The latter are probably easy to come by, the low profile ones might be a different story.

Yes mine came with open ended, low profile nuts that bolt the spacer to the hub and the I'm using the factory lugs on the wheel. I agree with Ericc B, I think you got the wrong spacers.
