Thanks, I appreciate your help on this too.

I ordered the 20x10 +22 front and 20×11 +28 rear.
What if I went with a 285 30 front and 305 25 rear?
By the way, my current front camber is -1.4.

Unsure about fitment of wheel's; But the 0.8" diameter tire difference may trigger the "Christmas-Tree" effect....definitely will have negative rake.

20x12 +22's w/325's will be a more even fit; as the 11" +28's are gonna be sunk in 1" vs. front & that's more sunk than my +38 19x12's....OZ listed 2 tire sizes that stay within limits of red-flags....usually around 1/2" diameter difference is acceptable.
I've heard 3%, but have alway's stayed closer to 2%max.

Since I've already ordered the 20x11 +22's, I'll have to work with those. I was looking at nitto invo and wanted to go 315 but they only have 35 series in 20's. I could go to a 275 front so I would have 275 30 front and 305 25 rear or 275 40 front and 315 35 rear.

Here's some more info.
275 40 20 has a tire diameter of 28.62
315 35 20 has a tire diameter of 28.62

275 30 has a tire diameter of 26.5
305 25 has a tire diameter of 25.94

Do you know what the stock 19" Bridgestone diameters are?
26.8 Front?
26.5 Rear?

Yep, 26.8F 26.5R
They come with a slight bit of negative rake from factory,
Nismo has 285/35's & are 26.9" in rear 26.8F
Base model 18's 225/50,245/45 are 26.9F 26.7R...not un-common to have slight neg. rake
I chose to have a slight rake w/26.8F & 27.1R....it's all about what "You" prefer.

I'm running invo's & they ride excellent and perform well-even in heavy rain...they just don't like to grip in 40'ish degree weather.

Tire specs will vary, pending on mfg. here is another option for sizes/ as Michelin is phasing out the PSS’s and going with the new PS4S...here’s a staggered option you can look at.https://uploads.tapatalk-cdn.com/201...72643725f2.jpg Front https://uploads.tapatalk-cdn.com/201...00cc0db9ce.jpg Rearhttps://uploads.tapatalk-cdn.com/201...28169f832e.jpg vs. the new PS4S...they offer just 1 spec in these.

Well, I ended up getting Nitto NT05's. 255 35 front and 305 30 rear.

That’s a soft,Mean looking Tire!

BBK clearance minimal
 

So I just got my winter wheels and did a test fit on the front (XXR 530, 18x8.75 +33). They clear the BBK and spin freely, but there is minimal clearance (maybe 2-3mm) with the eye test. Should I be worried running it this close? If so, can I get a 5mm spacer to work without extending lugs? I'm supposed to get these mounted with X-Ice next Monday so I don't want to run into any problems when I hit the tire shop.

5mm is fine
hell, i think they make 3mm spacers but thats less common in my experience

Do you think I'm ok without them though, or would it be wise just to get some 5mm spacers?

I got a good price on them with the discount that discount tires has right now on their ebay store. Wheels and tires are being delivered tomorrow, just in time to get them installed before my car goes in on Tuesday for the new supercharger tune. :driving:

I test fit my wheels and tires today. 20x10 +22 front and 20x11 +28 rear with 255/35 front and 305/30 rear. Car is in the shop getting the supercharger installed. There are a bunch of parts off the car including trans (new clutch). Car is up on 4 post lift. We set the car on the ground and the rear is fine, tires are a little tucked in the wheel wells but I have about a half inch of poke outside of the wheel wells on the front. I know the suspension isn't settled and if the camber will change any when settled. I'm currently set at -1.4 camber front. I'm wondering if I need to run more negative camber or if I need to go to a 9" wheel and or a different offset.
