IRC factory settings are -0.30 degrees for camber and 0 for toe.
The more negative camber you run the faster your turn in speed into corners etc can be, but you'll sacrifice tyres for this. The more negative camber you run the quicker the inside of you tyres will wear.
Just out of curiosity how much were your arms, ball joints and bushes? I'm thinking of doing this lot soon too.
I cannot remember the individual parts prices but the list was:
- New left & right front arms
- TT bushes
- Both ball joints
- Top mounts & bearings
- Wheel alignment
This lot including labour cost me £500.
