350z Tire/Wheel Fitment 18x10 inch 305 V710s

This evening after work I came home and cleared out the garage so that I could get the new wheels test fitted to see what all I was going to need to do on Saturday.

Here are the details, the wheels are Enkei RPF1 18”x10” +38 (offset). The tires are Kumho Ecsta V710 305/30/18s. The car currently sits on a stock suspension (2004 350z Enthusiast)

With that in mind, I wanted to see what I was going to need to do to make them fit on the car so I can run them at the SCCA Autocross this weekend. The good news is that the wheels/tires fit on the rear perfectly, no changes necessary (at least as of right now on the stock suspension).

The wheels and tires unfortunately do not fit on the front, but I kind of expected that, and was surprised they fit on the rear without any trouble. So in order to get the wheels on the front of the car I’m going to need to do a few things.

I need spacers up front, I test fitted a single and double 5mm spacer, 5mm wasn’t enough, but 10mm looks to be right. So in the front I’ll need 10mm at minimum, though I may order a few different spacers for future needs.
Longer studs, I ended up ordering some ARP Studs (part number 100-7717) from www.soloperformance.com via special order. They should be here Friday, in time for me to install them on Saturday. I ordered rear studs as well, but may not put those on immediately.
New lug nuts, with the longer studs I’ll need an open lug nut, I’ll pick those up at autozone or kragen.

I think, and we’ll see in a few months, that I can probably get 315s all the way around on these wheels, and with appropriate spacers, that 315 will fit.

Here’s a video from the time in the garage tonight.
