XRAY - Model racing cars

With former cars I owned, not XRay, I used to drill the shock caps with 1mm and did not use the shock foam inserts.

Anyone any experience on this matter as to XRay cars? (especially T3/T4)

Using the shock foam insert or not?

Hi,

there is a hole in the shock cap already so you do not need to make another one

Well I use foam in low-medium traction conditions to get slightly more steering. In high traction conditions, I do not use them in order to make the car easier to drive. But to be honest the difference wether you use them or not is not very big
