Wishbone mounts / Walk
tony_danza:
The S3 bush is different to the Golf one, so I think if we're talking about 3/4 stages of upgrade it is relevant.
Stock (soft)
S3 (harder)
Poly (hardest)
WALK (Poly + caster increased)

Adding castor gives you something called dynamic camber. Much better than static camber for a road car, this is of benefit because it doesn't wear the tyres unevenly when going in a straight line, yet it gives camber when the wheels are turned.
In simple terms, it pushes the lower part of the strut forwards meaning the point of axis is forward of where the tyre touches the tamac causing a trail effect, like a chopper. If you think about turning the wheel on a chopper, it leans, developing camber when done but runs true once straight. It also has the effect of pushing the inside wheel down, lessening the effect of inside wheelspin.

that explaination from Whiteline Australia / Balance Motorsport was good wasn't it! :wink:
tony_danza:
Yes Chungster, it's basically what I can remember from when I wrote that initial review and Whiteline's addition... I only understand the basic theory, I couldn't tell you about combined effects of various aspects of geometry on each other.
I've tweaked my bit up there too.
chungster:
did u beat your time from last year yesterday??
yours looked rather good on the track i have to say.
tony_danza:
Took over a second out of it, very very happy.
