I need to check the camber specs. Before upgrading my wheels and tires, I was running the enthusiast stock setup - 225/50x17 FR and 235/50 x17 RR. Now I'm running 255/40x18 FR and 275/40x18 RR on 18x9.5 wheels FR and RR. I hope a camber adjustment can fix the look. Having the 255s up front sure makes the car handle better! And the 275s in the rear help a lot as well. Now I need to install my Hotchkis sway bars, but wanted to see what the difference in handling was going to be by just switching to the larger wheels and tires. I guess I'll need an alignment anyways niow that I have switched to the larger wheels and tires.
What are your camber specs though? If you're in the safest range then you'll see what you're seeing, but if you go a bit more aggressive with the front camber it won't look like that. I'm running an 18x9.5 +20 up front and know exactly what you're saying, but with more negative camber (set for autoX not for this look) that effect went away.

MORE - My cross camber specs are +.2 based on the alignment when I had the 225/50x17 up front. Left is -.8 and the right is -1.1. Will going to -1.3 help?

Wheel Fitment Help 18x9.5
I have 18x8 +30 fronts and 18x9.5 +26 rears
I've got 245/45/18 tires for the fronts at the moment but have no idea what to go for the rear. There is a set of 275/40/18 and 275/35/18 on sale locally but how would that look? Thanks guys

You will need 275/40 which will match the same front diam. Stock stagger (difference front rear) is almost 3% LARGER diam rear, but you'll be ok even with VDC present. BTW, 275/35 would make rears SMALLER in diam than front. If you had VDC, it would trip the VDC system alert constanly with those smaller rear tires.
Having said all this...you will be told to SEARCH here for this info, which helps keep down the # of threads created. Also, in that search, you would find this tire size calculator:

Those fronts are really too tall...ideal for stock diam would be 245/40 (225/45 is stock size).

Old setup. Kinda. I sold the p45r's, put my other 2 grids on. But now the grids are my drift spares and I got some Weds for the street, so I'm super stoked to see how those fit compared to these. The grids poke in the back. Looks pretty rad. I'm planning on snapping some pics soon.
18x9.5 +20 (20mm spacer)
18x9.5 +30 (25mm spacer)
245/40/18 Nitto Invo front
245/40/18 Federal 595 back
-3.8 camber up front
-1 back

Thanks man. My new street setup as of yesterday, events still gonna do the mismatch dealio 
Unfortunately only have instagram pics at the moment, but I'll definitely be taking ones with a better camera soon. Being an idiot and rushing to get to Discount to get tires mounted before they closed, I was using a jack that only had half of the handle and as I was lowering it the jack slipped and went right onto the oil pan. Taking the pan off today and banging it back out so I can drive the damn thing again. But anyway here are some instagram pics.
WedsSport SA-60M
18x10 +20 (20 or 25mm spacer up front, can't remember)
18x10 +20 (15mm spacer round back)
-3.8 camber front
-1 camber rear
Better pictures later, had to take them with instagram cause it was getting dark fast and had lots of other stuff to do.

^^ We run very similar camber haha. I PM'd you about splash guards not too long ago! Wish I could catch you at a drift event some time. Stopping my drift build for a little while, I need to focus on school :P Relatively new setup:
VS-XX 18x10 -20 235/40 and 18x12 -12 275/35. -4 in the front and -2 in the rear!

Offset question
ok I searched and broswed but found limited info .I want to pick up a set of rota p45r for now because I have a donut on my car right now. And then plan on trying to find a set of lmgt4s
My question is I was going to get 18x9.5 +20 and 18x10.5+20 rears with a 255/40r18 front 275/40r18 rear now with these these rims on a car they fit nice but when looking at a set of lmgt4 they had an offset of +12 front + 15 rears and I thought they looked like they had a deeper concave. Maybe it's just. Manufacture thing.
If I get a different offset will it affect what size tire I run I don't want them to cone out past the fenders any input would be greatly appreciated thanks
