Default Evergreen Speedway Autocross

First event with new Detroit TrueTrac, 4.10's, SKF hubs, UMI Roto LCA's and UMI adjustable torque arm. Really love how the car handles, think I finally have it setup how I want. Still understeers but with a bit of trail braking and stabbing the throttle mid corner I can get it to rotate pretty well.

2nd in class, 2nd overall:

Congrats on 2nd place, you can't be too upset with that. I'm sure all the new parts on the car will make for a learning curve for the first couple events.

What did you think of think of the SKF hubs? What about the 4.10 gears, were they difficult to handle in autoX?

The R888 tires are starting to look a little chewed up, do you expect to get another full season on them before they need to be replaced?

Thanks! I'm pretty happy with 2nd, guy in 1st was running a 1800lb SR20 powered Datsun also on R888's

Love the new hubs, abs works consistently and I don't have to worry about wheels falling off when I'm pulling 1+G's. Gears are perfect at least for this track. Before I would runs most tracks in 1st gear.

R888s are fine, I'll probably go with a 200TW tire after they give out, R888 need a lot of heat to get sticky. My 12th run was my fastest...

I wish I could get 12+ runs in at an autoX events. We're lucky if we can get 6-8 runs total for a day.

Glad to hear the gears and hub adapters are working out. Those are both on my list, although I'm looking at 3.90 gears.

With those 315's and the g's you're pulling have you done oil pan baffling or put in an accusump? Just curious if you're concerned about oil starvation.

This particular event is a non SCCA sanctioned event and they're really loose with the rules. There are usually 12-15 timed runs then around 10+ more fun runs in bonus time. It awesome for testing small shock or tire pressure changes to dial in your car.

As far as oil starvation, I'm not pulling those G's for more than a few seconds at a time so I'm comfortable just running 6qrts. Once I start road racing I may go accusump.

Course like that is begging for a trans gear change and running mostly 1st to really pull out of the tight turns.

No SCCA staff would be dumb enough to run there with objects so close

If you decide to get an accusump, hit me up. I have years of experience with mine and there are some snafu's I think need taken care of over and above their base install recommendation.

I thought the same thing, that wall on the left side was sketchy at 42 sec mark!

If you think that's sketchy, you should be there on a soaking wet day

I've seen the videos of wet events there. They are begging for a big problem
