The XRAY 303004 brass motor mount plate is a precision fitting part for the T4'18 chassis. Made from brass to replace the standard aluminium unit, it adds roughly 4 grams on the centreline to improve lateral balance and limit unwanted chassis flex for more consistent handling.
This motor mount plate includes extra mounting holes set toward the rear of the chassis to bias weight rearwards and improve grip. That configuration tends to steady corner exits and gives the driver more confidence under acceleration.
