Good lookin' ride
 

Brian, congratulations on completion, great color/wheel combo. Enthusiastic pit crew!

Question (not complaint) : how come so little caster? I would have thought at least 4* if not 6*? Seems like the alignment shop has used generic 68 Camaro reference data (which gives the red and green highlights) rather than contemporary set-up numbers?
Do you know the specs from your front clip vendor?

thank you! wheels ended up matching by luck lol. found them used on craigslist after i picked the body color

front subframe is stock, with a ridetech level 2 kit. handed the ridetech instructions to the alignment guy and said this is what i need

from my instructions when i bought the kit in 2015 - Have the alignment shop set the car with ½ degree negative camber, 2-3 degrees positive caster, and 1/8” toe in.

double checked my instructions with what is online now 2019 and they are different.....now online - Have the alignment shop set the car with ½ degree negative camber, 3-5 degrees positive caster, and 1/16”-1/8” toe in.

This caster setting sounds better.....assuming the arm geometry is the same as yours (same part number upper and lower wishbones) this will give better turn-in, slalom and high speed stability.

What about tire wear? Car will be 100% street use for now, no foreseeable track use

I would add a little more negative camber to help avoid any tire rubbing. -.5 degrees is good imho.

Too much caster can result in a fair amount of jacking. I had quite a bit of caster with my Ridetech Tru-Turn setup and the steering joints were groaning when I turned the wheels. Those heims are not very forgiving of dust etc imho....

Already had some rubbing. Replaced the outer fender bolts with button heads and made some room with some hammer taps. No more rubbing

I did the same thing.

There is a classic car cruise on 20th if interested.

Add some negative camber for increased margin.

99% of driving miles are run straight ahead, caster doesn't affect the angle of the tire relative to the pavement, so does not affect wear. It DOES improve stability and "return-to-center" after turning.

During turns, caster tilts the outside wheel inboard at top so preventing tire "tuck under" thereby improving tire life.

Extreme caster (8* and more) will cause tire wear and is too much on a wet road with low profile tires.....car will PUSH BAD.
Four degrees is very conservative.

Everybody needs "slalom" when that autonomous Tesla comes out of the side-street.......not just for autocross guys.

VERY simple explanation (there are other factors at work)::::Caster is the difference between shopping cart wheel flutter, and a bicycle when u push it along using the seat only. Caster being the angle of the head stem where the steering bearings are.
