Ultimate lower arm for road or race. Sold in pairs only.
One piece, forged, fully adjustable on the car lower arms (with knuckle for bushes) to allow adjustment for any camber setting required. It is recommended that you fit offset bushes for true geometry checks. 

Discard the eyelet for the bushes and you can fit spherical joint/rose joint ends for race use. Makes all other arms obsolete. When increasing negative canber ST Abingdon always advised fitting a 3mm plate under the top arm where the bump stop hits to prevent undue strain on the driveshafts.
