Due to an unexpected number of S1s finding ditches and hedges Lotus designed the S2 to be more road user friendly with an under steer bias (e.g. 175 section tyres) which can be addressed in the following cost focussed steps;

1. Learn to drive around it trail-braking in to corners and staying off the power coming out on a Walshy day or empty track.

2. Increase the front camber to -0.5 or -0.7 (340R Road see: [[ Geo_Setups ]] ) note that the S2 hub carriers or ball joint plinths will usually need to be machined down to get more than this (under steer 99% gon)

3. Fit 195 section tyres like TR1s (under steer 100% gon)

4. You do not need A048/R888 rubber to sort out under steer, with stiffer springs and dampers they will allow you to go faster through a corner

5. If you have adjustable dampers and run spring rates at the same % as weight distribution (generally 45%f/55r%) harder damping on the front = under steer, harder damping on the rear = over steer.

6. I have no real idea what a stiffer ARB brings to the Elise party, seems to be low speed under steer but high speed stability.
