I think I got it sorted. I'll get some proper photos later today. I will be interested to see what other folks 315 journey looks like. I'll miss the lower stance.

I'm also back on my project to get a set of non-shitty-to-work-with and legal fuca for the z. I picked up these arms from gk-tech. The plan will be to buy some rod ends to replace the sphericals on the inboard side of the upper control arm. My first thought would be to replace them with the rod ends from the z1 arms which are actually pretty nice. Unfortunately the z1 rod ends appear to be rh thread and the gk-tech need a lh thread. So where I am is I will need a lh thread 3/4 16 rod end with a non metallic cylinder bushing. There seem to be a few off the shelf options available at speedway motors and summit racing but I am open to other sources and input from anyone with fabrication experience.

Before they allowed sphericals in SP I went through the same thing for the rear arms. I just got the rod ends from Speedway and they've worked fine ever since. I did need tp have a local machine shop make me a few sleeves and spacers though to match the OE dimensions though.

Hell yea. You inspired me to try this. So far this is my most promising lead

So not only will it have 4x4 ride height but actual 4x4 parts.
Can't wait to trigger stance bois.

So, I ordered some 18x11 +24 custom made Forgestars. I'm thinking +24 might be a tolerable rub. If not, I'll add some small spacers. We'll find out in 5-6 weeks. I'm hoping to have everything squared away in time for Crow's CT.

Brendan · 03-19-2021, 09:44 PM

You guys. It worked. I'm so happy.
I will put a more detailed write up in my build thread but we have one more legal option for upper control arms.

With the right parts you might be able convert spl arms as well.

First event on the new tires. Photos showed I can go a bit lower than I had at the car. Also made some other tweaks to the suspension for the next time out. Grip is silly. This is from a practice event with a local club. I would have had ftd for my class if my buddy didn't decide to cheat and run an old set of hoosiers.

Brendan · 03-25-2021, 02:28 PM

Measured caster on the new arms, actually not as bad as I thought. +7.2 which is still way more than stock. I also went to -4 degrees of negative camber since I couldn't even get closer to locking up these tires and wanted some more clearance than I had at -3.5

ConekillerZ34 · 05-13-2021, 03:06 PM

Figured I owe you guys some 315 / 18x11 snapshots by now.

I'm running straight second places at local events so far, 2/3 with class-winning scratch times by decent gaps but this extra tire is picking up cones

We'll see how it goes nationally at Finger Lakes.

This is +22, correct? Any rubbing on the steering knuckle?

Forgestar apparently is having a material backorder, and so my wheels are expected until July, now. I might have to see if I can maybe get the +23 Enkei PF05's.

Yep, +22. Sucks about the backorder, I guess I skirted that just in time.
No rubbing on the inside. Minor rubbing on the outside fender tabs under significant bumps

Dude, with all this tire I need to win something. Gotta stop driving like a total spaz.
