Unlike most cars of its time, the Crossfire does not use a rack and pinion steering system; instead, it utilizes a recirculating ball system as employed on the donor R170 platform. Front suspension is unequal length (SLA) double wishbone suspension with 5 point multi link in the rear. Just like the concept car, all Crossfire models were built with two different wheel sizes measuring 18x7.5-inch on the front and 19x9-inch on the rear. Standard all-season tires were 225/40R18 on the front and 255/35R19 on the rear.
