I am putting my suspension back together at the moment and am wondering what to set the castor to. The build manual says 2-2-2 left to right i.e. 2 washers between the rear of the front wishbone bush and front chassis, 2 between the rear chassis and front of the rear wishbone bush and two washers between the rear of the rear wishbone bush and the chassis plate. However on my car which is a BEC(Blackbird) I had 3-1-3, I assume because it is light on the front end and moving the wishbone forward gives more positive castor and therefore better steering weight and self centreing? I may just stick with this, not sure.
So I assume this is how it goes:
0-4-0 Max negative castor wide track Caterham recommended ?
1-3-1 Half way house
2-2-2 Build manual, narrow track Caterham recommended?
3-1-3 Lightweight front end(BEC) for more steering feel, self centring.
4-0-4 Extreme positive castor.
