Definatly a wet weather set-up, I reckon it would be good on a clay or dirt track.

Did you have some picture to explain me where you using your dremel.
Did you dremel your motor plate?

This set-up is for the rear motor car and not the mid motor. All I did was cut out the back of the battery tray above where the front pivot block is. It allows you to move the pivot block up and down.

I have dremelled the motor plate on my Akula AKX2 SCT prototype to allow the pivot block on that to be moved up and down. But you cannot adjust anitsquat (increase it anyways) on the Tc02C because of the design of the rear end.

I have not actually done the antisquat mod either on the X-Pro. However have done it on the Akula, after a top recommendation, and its improved it greatly so would be worth trying. All you need to do is allow for clearance when the pivot block is raised.
