can't wait to get mine built and on the track to have a look at this understeer problem.

From my understanding it will be the high g corners where theres a lot of body roll. Aparantly there isn't enough camber gain on the front suspension, i.e the camber angle can't keep up with the body roll angle. Thus causing the outside front wheel to camber out under heavy cornering. Thus causing a bit of understeer. The front shock angle is also quite low so effectively you loose stiffness the more wheel travel (or roll) angle you see.

Three things I'll be playing with to solve this (or minimise this)
1. Static camber angles, probably come up with a track and road setting.
2. Limit the body roll with some antiroll bars (or stiffer strings)
3. Weight distribution etc to give a more neutral oversteer charactersitic.

Other than Ash I'm not sure who else has actually experienced the understeer and this could just be down to the basic geo setup.

As said on the road it isn't going to be a big problem, on track you might feel like you not quite getting the most from the tyres. No biggy.

In my opinion a wider chassis would look naff
