Track Suspension Settings
 

I thought it would be helpful for everyone if we could compile a list of suspension settings people have found works well for them on the track. I am open to any suggestions, but I think the following format would be a good place to start. I thought it would also be helpful to list your suspension components.


Settings:
Front Camber:
Front Caster:
Front Toe:
Rear Camber:
Rear Toe:


Suspension Components:
Springs and rates:
Shock/coilover type:
Front sway bar:
Rear sway bar:
Endlinks:
Bushings:
Front Camber devices:
Rear camber devices:
Wheels:
Tires:
Aero:


Notes:
(neutral, oversteer/understeer, allows good turn in, etc.)

There are like a gazillion permutations...

You'd also need to add in tire model/size, wheel model/size, aero, etc....

Settings:
Front Camber: -3.0
Front Caster: Stock
Front Toe: 0.0
Rear Camber: -1.9 (will change to -2.5 when rear LCA installed)
Rear Toe: 0

Notes:
Car is neutral with slight oversteer tendencies. Turn in is slightly slow

my latest set up, car feels slightly understeer if Apex too late, will keep this setting until CSG Spec Tein SRC shows up

Front Camber:-3
Front Caster:-7
Front Toe:0
Rear Camber:-3
Rear Toe:0

Car feels fairly neutral but getting some push on low speed corners; I suspect this is driver induced and I need to follow-up by examining my data. Some tire temps are linked here but I need to get off the track sooner so they aren't cooled off as much:

The Dunlops are much faster than the Rivals I had before but the car feels wobbly as opposed to solid with the Rivals. The Dunlops are good for 1.5sec on the road race track.

Neutral and fast. Handles imperfections/bumps with ease. Perfectly even tire temps indicates alignment and tire pressure are completely dialed in. Tons of grip with the RC1s.

2.2 -2.5 was plenty of camber for me
