I agree though 4mm seems like a lot to shim..
Wow, that is a unique way to run 1/12 scale... Anyway, you could also add shims to your kingpin under the steering knuckle in the front to lower your ride height, although this will adjust your roll center as well. I think the bigger issue will be the rear since you will need to shim the motor mounts up by 4 mm which will raise your motor and put more weight up higher.
