B15 Handling Pack - RCK and UPGRADED Bump Steer Kit

NOTE! YOU MUST TRIM THE FRONT OF THE LCA TO CLEAR THE ROTOR WHEN USING THE RCK with Brembo OEM Brakes. 1mm-2mm of CLEARANCE REQUIRED! Our kit is designed to raise the front roll-center geometry by using specially engineered ball-joints in combination with our 2JR Bump Steer Kit Tie Rod Ends while still maintaining original steering geometry. Sentra McPherson front roll geometry gets worse and worse the lower you go with your B15. Coilovers, sway bars and our LCAs help but dont fix the problem. Our testing proved that raising the front roll-center resulted in a substantial increase to front roll resistance and a huge reduction in suspension compression of the outside front wheel during cornering (less roll). This improves weight distribution & maintains a better camber angle which ultimately improves front grip. The overall outcome is significantly reduced understeer through reduced front wheel compression as well as improved steering precision & vehicle stability. The 2JR RCK MUST be used with our UPGRADED BUMP STEER KIT. So the steering tie rod angle matches the lower control arm angle. Easily accomplished with our spacers included in the Bump Steer Kit. No more twitchy, hyper-active steering. This is for the street, drag, autox and track. For cars that are lowered more than 1/2" over stock.
