I will assume that ride height needs to be addressed. Spec for the class is 5mm minimum. The tires are tall so you might need shimming to get close to that. I don't know how X-Ray adjusts rear height but on a car that accepts Associated type adjusting inserts, just find a set of #4. The front end will need about 2.5 to 3mm of extra shim. Don't forget to set the servo height for the front end change.
