Re: Front Suspension Global West
Caster +4.5 to +5 degrees
-0.5 to -0.75 negative camber
toe: 1/32" total toe in
This is very close to GW's recommended "street" spec with the inclusion of a bit more negative camber.
You may have to tailor to your exact driving style but the above will provide even tire wear with moderately aggressive driving with a B-body spindle setup. If you frequently hang hard turns, add more negative camber (try -1 to -1.25) and drop to 0 total toe. You can put cross caster in to compensate for road crown if you want, usually about 0.5 degrees of cross-caster takes care of any pull to the right due to road crown. I prefer to run even caster and just live with the pull to the right on very crowned roads.
The pull you are experiencing may also be the inherent bump-steer of the B-body setup in combination with a loose steering box/tie rods/drag link. Check the steering linkage ASAP as any slop there will let the toe "flutter" which wears tires VERY quickly. My experience has been the drag links get loose quickly on these cars, I usually change mine as soon as they become noticeably loose, which for me is about every 10-15K miles.
If there is no slop in your box or steering linkage, it's probably bump-steer you are dealing with (which is bad with a B-body spindle.) Does the pull primarily occur over bumps & road irregularities?
Old setup: Procharged/intercooled/EFI 353 SBC, TKO, ATS/SPC/Global West suspension, C6 brakes & hydroboost.
In progress: TT LS2, T56 Magnum, watts link, Wilwood Aero6/4 brakes, vaporworx, floater 9" rear, etc.
