Just finished my 420r build have ride height question

[BruceBe]

To eliminate tire/wheel sizing variables, we use an angular  measurement/reference at the front LCA, and then also set rake based on an angular reference ( by adjusting the rear). This usually works out to be nominally close to CCs published numbers, but not with all tire/wheel combinations. Deviation from that is a performance compromise, but that’s ok as well in a mixed-use car. Generally, raising the platform will increase toe in the front and reduce camber. So, if you make a big change to ride-height, those settings should also be re-checked.

 

And as John pointed out - vehicle should be loaded with driver weight, half tank of fuel, and tires at desired hot pressures.

 

Cheers,
