Front Lower Control Arms: Part # (SPL FLCA F8X)
BMW F8X Front Lower Control Arms (FLCA) provide roll center, camber, and track width adjustment for the F8X BMW M2/M3/M4, and allow for full articulation with the proper ball joint angle. The main arm is slotted to allow the use of pinch bolts, and our rotating clamps on SPL Parts' exclusive Double Adjuster lock down camber and track width settings. No more jam nuts!! Long gone are the days of fumbling with multiple wrenches to tighten jam nuts in place while trying to keep your bearings oriented correctly.
Our Double Adjuster is machined from 4130 Chromoly; gun drilled to reduce weight, then electroless nickel plated for corrosion resistance. Blue Anodized Titanium hardware shaves even more unsprung weight from the arms without compromising strength. Stainless Steel spacers are provided to correct roll center for lowered vehicles. The use of FK Rod Ends and High Misalignment Spherical Bearings eliminates the flex and binding found in the OEM control arms, while allowing smooth articulation. The street version includes the headlight adjusting rod.

Front Tension Rods: Part # (SPL TR E9X)
BMW E9X/E8X/F8X Tension Rods (TR) provide a wide range of front caster adjustment, allowing precise alignment for optimal turn-in response and to compensate for variances between left and right caster. Low-friction, smooth articulating FK Spherical Bearings eliminate the stock mushy rubber bushing to provide a more responsive steering feel. Anti dive geometry can also be tuned with the use of our stainless steel spacers
Our parts are engineered for maximum performance. Billet Aluminum alloy 2024 hex rods are precision CNC machined and gun drilled to reduce unsprung weight while maintaining high strength and stiffness. Our exclusive 360 degree Rotating Clamp design allows for easy access to quickly and precisely locking in your desired alignment settings. Blue Anodized Titanium hardware shaves even more unsprung weight from the arms and offers superior strength.
FK Bearings Rod Ends are manufactured in Connecticut. The JMX is an upgraded harden rod end used for superior added strength. Featuring a Teflon liner to provide quiet operation, low friction, smooth articulation and eliminates bushing deflection under load. The PTFE liner is chemically bonded to the inner diameter of the race. The liner offers a very high load carrying capacity and has greatly increased dynamic wear characteristics. The operating temperatures of the liner ranges from -65º to 325º F, offering robust reliability for both street and track use.
- Gun drilled and Black Anodized 2024 Aluminum links to reduce unsprung weight
- Blue Anodized Titanium socket head cap screws
- Rotating 6061-T6 Aluminum Clamp design
- Hardened JMX high misalignment low friction 3 piece Teflon lined FK Heim joints/rod ends
- Stainless steel anti dive spacers
- ASTM A574 socket head cap bolts used for maximum articulation with minimum tensile strength of 170,000 psi
Front Caster Rod Bushings: Part # (SPL CRBN E9X)
SPL Parts FKS Series BMW E9X/E8X/F8X Non-Adjustable Front Caster Rod Bushings (CRBN) replace the stock flexible rubber bushings with low friction, articulating Spherical Bearings eliminating bushing deflection and reducing friction. This maintains optimum suspension geometry under load to improve braking and handling feedback. Massive 1" sized FK Racing Bearings with self lubricating Teflon liners are used to ensure maximum performance and durability.
- 6061-T6 Aluminum bearing housing with outer knurl
- FK Teflon lined 1" spherical bearings
Front Adjustable Caster Rod Bushings: Part # (SPL CRB E9X)
Front Caster Rod Bushings (CRB) replace the stock flexible rubber bushings with low friction, articulating Spherical Bearings eliminating bushing deflection and reducing friction. This maintains optimum suspension geometry under load to improve braking and handling feedback. Massive 1" sized FK Racing Bearings with self lubricating Teflon liners are used to ensure maximum performance and durability. Innovative CNC machined offset bearing spacers provide +/- 2 degrees of caster adjustment. OEM arms not included.
- 6061-T6 Aluminum bearing housing with outer knurl
- 6061-T6 Aluminum offset spacers provide +/-4 degrees of caster adjustment
- FK 1" spherical bearings
