MCA 6000 WC are extended length control arms designed for serious competition vehicles such Autocrossers, American Iron and World Challenge cars and are very light weight but strong aluminum tubular arms. They also work well on Drag cars up to about 1000 Hp. A 4130 model can be special ordered for cars over 1000HP. Included are brackets and hardware to relocate the control arm forward and allow for vertical adjustment of the chassis mounting point which is a great tuning aid for both road racers and drag racers as it allows for biasing rear roll steer and/or rear roll steer independent of corner weights.
The longer arm length reduces the overall rear roll steer considerably from that of the OEM layout which is excessive. Teflon lined spherical bearings are used on both ends to reduce binding that can occur with more compliant bushings. They are light and strong. These are the same rear control arms used in many American Iron races by many different drivers including, Ernesto Roco who was victorious in winning the American Iron Extreme Championship in 2006. Like most of the products bearing the Griggs Racing name they are proven under brutal race conditions across the world to be the absolute best performance value.
