Set normal ride heigt of roughly 6mm all around. Set camber so both tires wear flat. If it is possible, try to use a TC shock with 40-45wt oil and 12 or 14 lbs spring. Put a bump stop on the shock. See if the front suspension works freely without binding or too much slop, same with the back end. I presume the car is ballanced left and right. Also the middle damper for side to side movement goes against the top podplate and chassis brace when moving to the extreme. Xray made a mistake on that one. You need to shim the topplate and shock attachement on the chassiss brace so the damper doesn't hit the upper podplate or the brace. The backend needs a little droop but the pod should be more or less horizontal when race ready. It is a base setting you are looking for for now.
See what the car does on the track when you made the above adjustments and try to describe if it has a tendency to understeer, oversteer, what it does going in the corner and going out of the corner etc etc. Pink back tires and purple fronts together with a peugeot HD has a tendency to understeer at speed.
Look at your steering throw. If you need 70-80% or more steering throw to go through the corners then you are scrubbing too much front tires and speed. It is better to build in more steering and less steering throw.
A 4t motor will scrub foam nontheless but one set of fronts in one run seems a lot even with a 4t motor.
