12:05 Garage- ’70 Duster build

Nice! :thumbsup:

I've been running about +6.5° of caster for awhile, I've been as high as +8° in the past and as low as +3.5°, at least with the way my car is set up +6.5° seems to be the sweet spot. I could probably run more but with 16:1 manual steering and 275's it starts to get quite a bit harder to steer as you start going past +6.5°. The jacking effect gets a lot higher past that point too, it really cambers the wheels a ton with turning.

I keep my camber down around -1°, my last alignment I was at -1.1°. But really all I do is street driving and a decent amount of it, if I drove less or did more autoX I'd probably go higher.

Did you get the 1st Gen SPC's or the new 2nd Gen ones?


Honestly, I've got you to thank for much of how my car is set up. I've learned a lot from your replies on various threads. So, Thank you!

When I started, I had a normal alignment (don't remember the specs) and that wore tires our very quickly on the autocross. I stepped to -1 camber, maybe, and it still seems to wear the outer edge of the tire, but was a little better. I'm hoping these settings get the tire flatter in the turns.

Funny you mention the camber with the wheel turned. When I got home, I turned the wheel to check it out. I snapped a pic to send to a buddy.

I got the first gen. I couldn't justify the additional cost. I'm not a good enough driver to even realize the difference.

Damn I need to get some 275s on the front! I may end up getting the wheels I have widened. Rocket Racing sold out to Holley and they immediately discontinued my wheel. I was hoping they would have expanded the size offerings. SMH.
