Washed the car and on the way to the house today after work and found a place to pull over a take a few pics with the APEX square 255 set up on. Thoughts?















OE wheels at the house:

not bad, you should have went up to 19's though. would have looked sportier. but 18 would be comfy. hows the weight of the heavier tires?

This wheel set up was actually for the track, just liked the feel and lessened understeer running 255'a on all 4 corners so have been driving around on them

Too much gap.....
Just say'n

I like it! Car looks good with the ARC-8 wheels. I've been wondering about getting the same wheels in the same size, so thanks for sharing the pictures.

What colour are the wheels btw?

Thanks, they are Anthracite.

Would look great with a drop and black window trim. Love the Med blue.

[RedKloud]

Nice wheels. Should also change the grill to black.

with that offset and wheel gap, there is no chance that he rubs ever.

love the arc-8's dude. a drop would look real nice with your setup!

i was thinking he may rub at full lock on the inside of the fender well or have very minimal clearance to the strut with the tire.

I ask because i have some 18x8.5 et40s that i want to get snows for and wanted to see if he had to do anything to fit this setup. if not, mine should bolt up no issue.

ah that's true, didn't think about the inside. it'll be close but i think safe.

Great choice with 255 square!

Thanks, couldn't agree more!

As to the rubbing others have asked about, zero, even at full steering lock. I've been driving on these since I got them a couple of weeks ago and have been checking the inside fenders to make sure. No evidence of even a minimal rub.

My fear now is that I won't want to go back to the OE staggered track-package rims once I track this set up at COTA in November!

PS those center caps on the wheels are not from the OE wheels, those were blue and white and looked lame on these wheels so bought some gray, black and white center caps off an eBay auction...worth the money!

Nice!!

Looks good! Love that mediterranean blue, trying to get the wife an X1 in that color.

Looks good. You are in a great place to provide us some insight into whether/how lighter wheels feel on the road.

I estimate the savings as follows

Front Wheels

• 26 lb to 18.5 lb wheels
• wider pilot super sport tires (225/45/18 @ 22lb--> 255/40/18 @ 25lb)
• 4.5 lb reduction

Rear Wheels

• 26 lb to 18.5 lb wheels
• the same 255/40/18 pilot super sport tires
• 7.5lb reduction

Do you notice a difference in how the car drives with the lighter wheels?
Please elaborate if you can.

[Sp82]

sorry bro, those wheels look horrendous. But if you like it, thats all that matters! congrats on the car!

[JV973]

Looks good, and with the m sport brakes even better.

The main thing I notice is the lessened amount of understeer, and again, the wheels on it are really for the track which is where I wanted a more neutral car.

I realize that I've lost about 22lbs of unsprung rotating mass which theoretically equates to about 88lbs of sprung weight, but my butt dyno can't really feel any difference in acceleration. Car is fast as is, so the .1 or .2 sec to 60 I may have gained is beyond what I can "feel".

One thing I did notice - and not sure if it was doing this with the stock track package wheels - is that nailing the throttle on the highway at speed with DSC off can get the tail stepping out pretty quick. Had to apply a good measure of opposite lock one time to keep from spinning into a car next to me and wall at about 70, yikes!

It may have been like that before, but I'm just now at 2K miles and wasn't pushing the car hard the first 500 when I had the OE wheels on.

I will be going back to the TP wheels once I track these next month. Pretty sure the MPSS' will cup and become unbearable to drive from the noise after beating on them at COTA like every other "street performance" tire has done.

Right on!
