Description
The BMW E30 PRO+ is a front suspension system designed for demanding motorsport applications.
This kit replaces the original control arms and reaction rods with a fully adjustable structure manufactured from 4130CroMo steel. Designed to offer maximum durability and adjustability without compromises. Both the control arm and the reaction rod are adjustable in place, allowing for rapid chassis setup changes.
Features:
- Control Arms: 4130CroMo construction. Features a 16 mm uniball on the body side and a 20/40 mm uniball on the wheel side. Adjustable in place (two lock nuts).
- Reaction Rods: 4130CroMo construction. Equipped with a “fixed” 4130CroMo joint at the control arm connection and an M18x1.5 4130CroMo uniball at the rear. Adjustable in place.
- Rear Brackets (Lollipops): S355 steel. DTM-style design: fits original mounting points but includes an additional mounting point to the chassis rail for increased rigidity. Height adjustable (shimmable) for Anti-Dive adjustment.
- Mounting: Weld-on bracket for the engine subframe with an alignment cone. Wheel-side mounting includes a 4130CroMo taper pin.
- Hardware: All connections feature 10.9 grade M12x1.5 bolts and nylock nuts. Reducers for 12 mm bolts included for uniball joints.
