Why do you need one?
When lowering your car (BMW E30 / E36 / E46 etc.) the front end geometry goes wrong. The main purpose of the kit is to correct these geometry issues.
The extended mounting stud changes control arm pivot point vertical distance by 20mm correcting the roll-center and camber curve.
Tie rod end pivot point is also changed by 20mm in vertical direction which corrects the bump steer curve.
Does it fit my car?
The kit can be combined with most of the E30 / E36 / E46 control arms and knuckles/spindles. See available variations:
Outer joint size:
- 48.5mm (E36 non-M / E46 M-Sport / E46 aftermarket)
Spindle/knuckle:
- E36 / Z3 non-M
Is it easy to install?
The kit comes with instructions, if you know how to change a control arm or an outer joint, installing this kit is basically not any harder. You'll need a press for removing the old outer joint and installing the new outer joint, no other special tools needed.
