The XLP2 shock parts are specifically designed for the smallest possible size to reduce the weight and keep the lowest possible CG.
Made possible by the shorter XLP2 shocks, new shock holders relocate the upper shock mount position 4mm than previously possible. The new geometry improves cornering speed, mid-corner steering and stability, and reduces traction rolling in high traction conditions.
The versatile shock holders use shims for adjusting the shock position in precise shock angle increments. The rear shock holder offers an Active or Fixed dampening setting in addition to the shock angle. All shocks are located 3mm lower, improving CG, cornering speed and stability, while also making the car easier to drive and more resistant to traction rolling.
Simplified shock mounting uses a captured mounting stud secured to the shock holder with a special setscrew. It is not necessary to use thread lock as the setscrew will keep the stud secure even during shock install/removal.
The new adjustable link upper suspension arms provide expanded adjustability choices beyond those of the traditional CFF™ upper arms for maximum adjustability and improve handling in certain conditions. Including the CFF arms and the new link arms in the kit offers the driver the freedom of choice to expand the adjustment possibilities of their X4.
The upper link arms provide fully adjustable camber- and caster settings using 2 turnbuckles in each upper arm at all 4 corners.
The turnbuckles are connected using ball cups from durable composite materials.
The X4 Caster Gauges, #302390, are recommended for enhanced accuracy when building and adjusting the link arms.
Wider wheel hubs now included in the kit for the best all-around performance out of the box. The wider wheel hubs provide more forgiving handling with improved cornering speed & stability.
The included wheel hubs work with the SCS – Spring Clip System for simplified installation. The standard width hexes improve overall stability and allow for greater cornering speed with reduced aggressiveness.
Graphite composite front and rear hubs provide the proper suspension geometry for improved steering and traction. The hubs contain small size bearings and a drive axle that moves the driveshaft pivot point deep into the hub, in line with the hub’s rotational axis between the upper and lower arm. This alignment improves driveline efficiency and handling.
The ultra-narrow wheel hubs are lightened for reduced rotating mass.
The hubs allow full adjustability of the axle height to adapt the car to every condition.
The design of the hub is universal with the same part used at all four corners with corresponding extensions. The aluminum front steering plates and rear ARS plates are easily mounted depending on the hub’s location.
