Asking $1600 local (delivery extra, I have small vehicles so transport is a pain). Currently located in Half Moon Bay, California, just south of San Francisco. It looks like 2012 will be a no go for me (no budget to get the car where it needs to be) so I am going to part ways with my beautiful 18x10" +38 Enkei RPF1s. The wheels currently have 18" 305 Kumho 710s mounted, plenty of tread left, though not competitive nationally, great for local/regional events.

I just don’t have the energy to do a full writeup for the ProSolo today, and to be honest, it won’t happen Sunday, and likely not Monday either Open-mouthed smile

So what happened? Well, I’m sitting in 5th out of 8, 2nd in the Kumho class. I’m still hoping to get up to first in the K Class Smile With the contingency available that would mean a set of tires.

Jodi Fordahl is driving with me as well. She’s doing great, I have a feeling she’ll be faster than me on Sunday.

Random note: This car really needs a diff!  I am going to try to find the OS Giken guys if they are at the Pro tomorrow and talk to them a bit.

How was today?


Hard to see but there is snow on them thar hills #autocrossBeyond that? Very cold and very wet. I went to Great America today for the SFRSCCA Divisional Autocross. I got there around 7am and put the Kumho tires on the car, big mistake! I was sort of drying out, the sky was almost clear, but the drive down there was rainy, and there was snow! You can’t see it very well in this picture, but yes, there was snow in the “hills” around the Bay Area.

So I installed the wheels/tires and walked the course a few times. The driver’s meeting got delayed, then the start of the event got delayed. Then the rain started back up Sad smile

Let me tell you this, Kumho V710s don’t work well when it is <40 degrees and raining. My first run I went out and it felt horrible, I turned a 66.*, I wasn’t too thrilled about that. Here’s a video of that run.

But I was too lazy to go get my street tires (freshly mounted the previous night mind you). Big mistake, I went out on my second run and decided I would take things slower, expecting to actually go around the course faster. I slowed down and ran a 69.*. That broke this camel’s back, I ran off to get my street wheels, drill, and jack so that I could swap to the Falken Azenis RT-615s.

Thankfully Grant (in a Nismo 370z) followed me over and helped me bring 2 of the tires back to my grid spot. I don’t think I would have gotten them changed in time had he not helped! Thanks for the help Grant!

The Falkens were MUCH better, not perfect, but way better than the V710s in the rain. I managed to run a 60.*, a big improvement over the first two runs, though I just wish I had put them on before my second run, or even to begin with!

Here’s a video of the third run

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.

  1. 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.
  2. Longer studs, I ended up ordering some ARP Studs (part number 100-7717) from 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.
  3. 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.
