Just received my Concept One CSL5.5 Wheels
 

Quick snapshot. Going on the Nismo this weekend. Unfortunately, still waiting for my swift springs to arrive however.

Ideas for which tire sizes I should get?

19x9 + 15 front
19x10.5 + 20 rear

I guess that would depend on the rim specs.

:iagree:

Added wheel specs.

Check out Tayloryan370's journal, he has the same wheels, I think he runs 255&295

How do I find his journal? I would really like to get in contact with this person as I have some questions about the fit.

The front's do not seem to fit the car. Since the car has less then 500 miles on it, I decided to use the stock tires that came with the car. So to clear things up, I'm running the following specs:

19x9 + 15 => 245/40/19
19x10.5 + 20 => 285/35/19

These wheels were purchased from GetYourWheels.com and Eric was very specific that I wouldn't have a problem with the fitment, but as you can see in the photos, I do have problems. The rears are perfect, in fact they could use like a 10mm spacer on the rear to even kick them out more.

Can someone with these wheels or similar specs chime in? Are you running aggressive camber, etc? How did you get these to fit properly?

You can find it in Member's 370z Gallery, page 3.

Thanks Zbrah :tiphat:

I think the front will be fine once you drop your car due to negative camber. But I do think you will need a spacer in the rear to have them sit more flush.

Install is scheduled for Thursday so I hope so as well.

too late now, but those are 350Z/G35C offsets. you need to run considerable negative camber to make that fit and slam it.

That's why I did all the research (pestering kenchan) before the purchase.

Kenchan, what is considered considerable? I am installing my Swift Spec-R springs this Saturday.

I was told lowering the car will help along with running negative camber but maybe someone could elaborate as to why lowering would help.

I was told by Get Your Wheels that these would fit with no issues. I did however mention I was already lowered on Swifts.

Eric was very quick to reply to my emails so I am really hoping I will be OK once I lower and run some negative camber. Stilling waiting on a reply from TaylorRyan370Z which will help me as well.

if i was going to run swifts, i would probably run 19x9 ET25-30 range or 19x9.5 ET30-35range, and rear 19x10.5 ET10 - ET16 range.
