To much caster?

[jannes_z-28]

I did a proper alignment on my car yesterday. Previously I have done it myself with some primitive device. On the rig the settiings I had accomplished wasn't to far out from the specs.



I have now set it to the following.
Camber -0.8°
Caster 8°
Toe 0.5°

This is with SpeedTech arms and Guldstrand mod on stock subframe.

I had opted for 6° Caster but it wasn't possible. My control arm bolts was to short for that.

I have seen recommendations on 6° caster and wonder if my 8° are to much?

It feels good now on the road. On sunday we will have a trackday and then I can check it out properly.

Eight degrees caster shouldn't be too much...it's certainly a bit more agressive than most street alignments for a first gen, but that's okay so long as you don't mind the increased steering effort and slight increase in tire wear you either may or may not notice. I'd say that if you like how it handles, who cares what the numbers are?

Beautiful car by the way. Is that Corvette "Machine Silver"?

Thanks,

I don't mind about 8 degrees, it feels really stable on the road.

The color is "69 Cortez Silver"

On a first gen Camaro, bumpsteer might go into reverse with high amounts of caster. In that case, under bump conditions, (braking) the wheels would toe-IN instead of the usual toe-OUT problem we usually see.

I had one report of this happening at around 6.5 deg positive caster.

+8* should work okay but the car probably won`t turn in a crisp as it could and may be a bit lazy in transitions (S turns etc.). Also watch your tire clearance in the rear upper part of the wheelwell. +8* moves the top of the tires toward the rear of the car a lot! You can do a quick bumpsteer check by measuring the toe in then jacking the car up by the crossmember and checking it again. As David said they`ll typically show toe in in droop/ toe out in compression. At 8* you should have a fairly small change. With all due respect to David in my experience measuring bumpsteer on a number of these cars caster change alone isn`t enough to fully correct let alone reverse the bumpsteer curves unless your bend the steering arms, are using tall tie rod ends or spindles with relocated steering arm mounting holes so I wouldn`t be too worried about that.
