This is a CNC-machined aluminum front knuckle for race cars based on the 1988 Pontiac Fiero. It solves the problem of wheel bearing failures when driven on the track. This bespoke steering knuckle utilizes a heavy duty wheel bearing that holds up under track use with racing slicks and high downforce. The ball joints are also upgraded to heavy-duty units for increased strength and durability. Furthermore, the stock single-piston sliding calipers are replaced with larger 4-piston or 6-piston Brembo calipers with 12.6" to 14.6" brake rotors.
This front knuckle fits ONLY the 1988 Fiero. It does NOT fit 1984-1987 Fieros.
Installation of this part requires the Mixed Surface Heavy Duty Control Arms Kits (both upper and lower) and 5x120 wheels. It may also require the use of a larger master cylinder depending on your braking system.
