Sold in pairs (covers either your front or rear wheels).
Whiteline knows that to gain maximum performance from your car, you need a suspension that takes into account changes to the road and demand put on the suspension. Whiteline's Control Arms are designed specifically to fulfill this need. Each arm is first reverse engineered to provide maximum performance while still bolting on like a factory piece. For most applications the arms are adjustable by a turnbuckle design, so you don't have to remove the suspension or even the wheel to set them. This also means you can weight the car to account for the driver's weight as well.
Although most applications feature adjustability, even the non-adjustable options will significantly strengthen your BMW 4 Series M4's suspension and provide a setup that will accommodate changes to your suspension geometry. Each kit comes with all the required hardware if anything beyond the stock bolts are required. If getting the most grip possible is your goal, Whiteline Control Arms are the way to go!
