As stated above, Castor is the way to go, not toe-in. I used to autocross
my 1980 Buick Regal Limited. Yeah, yeah, yeah, I know, but it was fun
anyhow.
To get it to handle better, I raked the castor out to 11 degrees, leaving
toe-in and camber at "close to" factory specs. The result was almost no
discernable difference at normal cornering speeds, but GREATLY improved
cornering (and relatively even tread temperatures) when it was pushed hard.
BTW - the KYB high pressure nitrogen gas shocks at each corner, progressive
wound, rear coil springs and police pursuit anti-sway bars at both ends made
this V-8 engined GM luxo-bloat-mobile an really fun sleeper. Oh, the
slightly lower/wider Pirelli's gave the secret away a little, especially on
the road, with the tacky, wire wheel look alike, hub caps in place.
This car and I did well on the autocross circuits. I recall quieting one
autocross starter who announced me as
"Number 19, Jack Brooks, driving a 1980 Buick Regal, yes, I did say a Buick
Regal. You need to see this one folks."
Bastard! I think that was the primary reason I took second in class that
day against mostly small Japanese cars.
In summary, for you autocross wanna-bees, the two biggest, cheapest gains
are made in suspension and driver seat time.
See ya' on the autocross circuit in my TR3 at VTR-99,
Jack
