Anybody running 17x8.5 square?

[stephenkirsh]

Looking at a square set up with Apex arc-8 17x8.5.

Do my reasons add up?:
- 17 pounds per wheel (9 pound savings over 135s, 1.2 pounds over their 18")
- Cheaper than 18"
- Tires look to be $30-50 cheaper on a 17" than an 18"
- Slightly softer ride

Questions:
1.) what tire size would be appropriate?
2.) how reputable are Apex wheels?
3.) any reason not to go with 17" (besides appearance and lack of BBK compatibility)

Thinking is sound. You did not include the off set of the wheels, so we can back you up.

I'd probably run 245/255's on those.

Apex wheels are reputable. You can run certain BBKs.

Do my reasons add up?:
- 17 pounds per wheel (9 pound savings over 135s, 1.2 pounds over their 18")- Yes
- Cheaper than 18"- Yes
- Tires look to be $30-50 cheaper on a 17" than an 18"- Yes
- Slightly softer ride-Yes

Questions:
1.) what tire size would be appropriate? -If you are going squared, then run 245.
2.) how reputable are Apex wheels? -When they are selling over 100 sets 2 years in a row during a Group Buy, then yes they are reputable. I haven't heard of anyone having any manufacturing issues. I've had mine (18") for 18 months and couldn't be more pleased.
3.) any reason not to go with 17" (besides appearance and lack of BBK compatibility)- Depends on what you want them for. Aesthetics? Go 18". Track use? Go 17" if not doing a BBK

Anything to worry about with offset? I wasn't expecting to need spacers. I'm only just learning what it is.

Yea my plan was 255s.

BBK isn't an issue; too hard core for me.

ET 42mm is a good offset.

1. 245/40/17 or 255/40/17.
2. They are fine. Tons of people use them without problems.
3. BBK compatibility is fine. It can clear the 135i setup without spacers. Stoptech with spacers. Besides appearance I don't see any real reason to say no to this.




My specs 17x8.5 +40 running 245/40/17 squared. The contact patch from the Direzzas is a bit similar to other brand's 255 so I'm okay with it. 255/40/17 is also fine which is what I plan to change to after these tires go.






Currently I am using a 12.5mm spacer to clear the Stoptech BBK in image 2. I believe a smaller spacer will work but I have not tried yet. I am currently looking for a 7mm spacer to try or a 5mm spacer.


I personally think the 17s look more aggressive than the 18s when paired with beefy track tires like this.






Dario,

the 17x9 is + 42 but the 8.5 is +40.

Awesome write up, thanks derbo.

Were you on 135s before the apex wheels?

The APEX rims are my track setup wheels. I don't daily drive the car anymore and the tires on the 135s are end of its life. My car looks better with the APEX wheels since I have the recaro and stoptech installed.

I run 17x8.5 TRM C2's (ET40) with 265/40/17 Dunlp Z1's. Very "stuffed" look. I love it. Aggressive.
