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.\u003c\/p\u003e\n\u003cp\u003eThis front knuckle fits ONLY the 1988 Fiero.

Fabricated from precision laser cut and CNC bent steel and welded in the USA, these rear uprights are the most robust upgrade for the Fiero rear suspension on the market.\u003c\/p\u003e\n\u003cp\u003eFor safety, the wheel bearing (not included) is upgraded to a much more robust design with a 5x120 pattern and large 33-spline axle. This is one of the strongest, largest wheel bearings available to support high racing speeds and high downforce cars with 2+ G's cornering forces. The upgraded axle splines hold up better to higher torque output, short final drives, and hard drag racing launches. This is supported by the trailing link boss which supports the link bolt in double shear for better strength and safety. In addition, the brake caliper mount is unitized with the hub carrier for the greatest ultimate strength, and is directly compatible with factory Brembo 4-piston brake calipers (not included), a significant upgrade over the stock 1-piston sliding calipers.\u003c\/p\u003e\n\u003cp\u003eTo ensure the lateral links are capable of surviving punishing cornering loads from high downforce cars on slicks and R-compound tires, the link clevises are now in double-shear, with two shorter, stiffer bolts replacing the problematic and hard to find long bolt used in the factory uprights.\u003c\/p\u003e\n\u003ch2\u003eImportant Notes\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eFOR OFF ROAD \/ RACING USE ONLY\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eONLY FITS 1988 FIERO REAR SUSPENSION.
