Ultra-light, ultra-strong eccentric upper clamp for ball-bearing (without use of composite hub), CNC-machined from premium Swiss 7075 T6 aluminum. Eccentric upper clamps allow movement of the rear axle 1mm forward or rearward depending on the clamp orientation. A shorter car rotates faster in slow corners and has improved forward traction. A longer car is freer in high-speed corners and will feel more linear, especially during fast direction changes. Additionally black coated for long life and stylish look. Identical left/right. Fits aluminum rear bulkheads with quick & easy ride height adjustment. Two pieces are required for assembly. Fits X12 and X1.
