I asked for some common street track alignment specs here. The majority of the responses I got was -1.0 front and -1.5 rear, max but equal caster.
I used the corner balance calculator here
http://vintagebus.com/cgi-bin/balance.cgi to figure my corner balances. However, when playing with my older Ruggles scales tonight, I noticed a fairly serious discrepancy in the accuracy. If I would stand on one scale, it would read 240, then to another 218, then another 223, and another at 238. Hmmmm, using 4x multiplier for the rear....makes accuracy out the window. Anyone ever tried using different scales other than the Ruggles ones? Looks like an ordinary bathroom scale to me.
Even so, I still have a really hard time believing the corner balance is causing all of my problems....the car was lowered by the PO, when I spoke to him about it, he said he just crawled under the car and adjusted the fronts down, and lowered the rear spring plates as low as they'd go, didn't balance the car at all, only had a basic alignment done, cost him 50 bucks. Car drove perfectly straight. Even when I got done with the torsion bars and test drove it un-aligned, unbalanced, it drove straight, didn't pull. Only thing I did was take it to the alignment shop and now it pulls.......????
Once again, how important is that caster number, how close is close enough?
