Someone else had said they would create a T4 model. Unfortunately I haven't received it yet. You should be able to modify the T3 model. From what I understand the main difference is shorter shocks and the shocks are layed down more. If I could get my hands on one it wouldn't take long to modify the model.

I'll keep my fingers crossed the model shows up. That's probably my biggest problem. If I could get a model for every chassis out there it would make things so much easier. That is just not possible as I don't have an unlimited budget.
