Set of 2 molded harder-composite front upper suspension arms for XRAY M18 and NT18. These new arms have the same camber (-1°) as the stock upper arms, but less caster (6° caster vs. 12° caster stock). These arms provide improved steering, better handling into and out of corners. Highly recommended for serious racing and high competition… prepare to drop your lap times!

These new arms should only be used at the front of the car, not the rear.
