There's no problem with going with larger wheels & tires early. I'm running 17x9 +63 255 with Nitto NT01s all around so I like that size and I've heard great things about the Star Specs.

Good write up! I thought that the rear uprights for the cage were not supposed to go further rearward than the rear most suspension point though? Also, for mounting the harness on the outer edge, did you simply use the stock point?
I don't know of any limitation on the rear roll bar attachments, I think the further to the rear they are the safer the cage. The rear supports are welded to the X-Brace frame beams.

I am using the outer stock seat belt mounting hole.
rob, do you think i can run 255 square on stock suspension without rolling the fender?

It depends on how low you are and your camber setting.

Large line at the front. When I get home I'll take a couple pics. I thought about putting it on the PCV also but ran out of initiative.

Wow, my memory's worse than I thought. How surprising.

Turns I plumbed into the PCV line:

Thanks for the pic and confirmation on the plumbing. I'm pretty sure my tank is just too tiny to actually remove the stream of oil moving at high speed. For me I get the smoke puff after a long right hand sweeper then close the throttle to up-shift (creating lots of vacuum in the intake manifold) and the oil is sucked through the PCV valve line and into the intake manifold.

It will be an easy upgrade to a larger Home Depot air/water separator.

Weird I could have swore I read that somewhere but I just browsed through the NASA and SCCA rule books and didn't see any mention of it. Oh well

Rob, a tip on your catch tank/pcv issue: vent the catch tank to atmosphere, or said another way, eliminate the return line from the catch tank to the intake manifold. Some could argue that this is not the most ideal solution as we lose some of the desirable functions of that vaccum, but I found that the vaccum created by running that line back to the intake manifold "pulls" an excessive amount of oil through the PCV and into the catch tank. I once had my lines routed exactly as yours are and I was filling up a .5qt catch tank in 5 laps around VIR! I remidied this by placing a breather filter on the return fitting of the catch tank and capping the fitting on the intake manifold. Problem solved! Now, my catch tank will have only about an ounce of oil in it after a full weekend.

Awesome website, BTW!
