New Suspension Products from SPL Parts, Inc. - Toe links, race control arms, etc.

Here are some new additions from SPL Parts for F8x M cars.

SPL Bumpsteer Adjustable Tie Rod Ends E9X/E8X/F8X BMW

SPL front tie rod ends allow the tie rod end pivot to be relocated, which will correct bump steer resulting from modified caster or lower arm geometry, thus reducing lap times. On cars that are lowered significantly, relocating the pivot point will also keep the tie rod end from binding, thereby preventing the inner tie rods from breaking or bending when racing.


SPL Adjustable Tie Rod Ends Feature:
• ASTM A574 socket head cap bolts used for maximum articulation with minimum tensilre stregth of 170,000 psi
• Gun-drilled 2024 aluminum turnbuckles to reduce unsprung weight
• High misalignment low friction 3 piece Teflon lined FK Heim joints/rod ends
• 1/2", 1/4" and 1/8" thick stainless steel bump steer spacers for precise adjustment
• Blue anodized titanium jam nuts

Sold as a pair



SPL FKS Front Caster Rod Bushings E9X/E8X/F8X BMW

SPL Titanium Series Adjustable Rear Upper Wishbones (Camber Links) BMW E9X/E8X/F8x

Our SPL FKS front caster rod bushings replace the stock flexible rubber bushings with low friction articulating spherical bearings elminating 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'd offset bearing spacers provide +/- 4 degrees of caster adjustment.

6061 Aluminum bearing housing with outer knurl
6061 Aluminum offset spacers provide +/-4 degrees of caster adjustment
FK one inch spherical bearings
Sold as a pair.



SPL TITANIUM Rear Toe Links BMW F8X M3 M4

SPL rear toe arms increase stability and response by eliminating bushing deflection while providing an increased range of rear toe adjustment, necessary for lowered cars or for performance alignments. Even small changes to ride height and camber will effect toe settings and the wide range of adjustment allows you to maximize grip on a track car and extend tire life on a street car. The factory rear toe arms utilize an eccentric bolt and washer for adjustment and lack the precision and range that SPL Parts rear toe links offer. Black anodized and gundrilled 2024 Aluminum main links along with our 360 degree rotating clamp design allow for quick and precise adjustment.

Gundrilled 2024 Aluminum Links to reduce unsprung weight
6061 Aluminum Clamps and Heim Joint Spacers
Titanium Socket Head Cap Screws
Rotating clamp design allows for easy access to lock down your alignment settings
Low friction 3 piece Teflon lined FK Heim joints/rod ends made in Connecticut
Optional Eccentric Lockout Washers can be purchased separately - http://www.splparts.com/products/spl...x-e8x-bmw.html

or as part of a complete kit - http://www.splparts.com/products/spl...c-lockout.html

Sold as a pair.



SPL TITANIUM Rear Upper Arms BMW F8X M3 M4

SPL adjustable links are an absolute necessity to maintain proper rear camber and reduce tire wear on the street and track. The stock BMW setup has an aggressive camber curve through bump travel, which is very apparent on lowered cars. Excess negative camber causes premature tire wear on the inside edge, and reduced traction on acceleration while too little camber will limit rear grip while cornering. SPL links provide a wide adjustment range for precise rear camber alignment that is easily optimized for street or track driving while eliminating bushing deflection with smooth articulating Teflon lined rod ends in place of the soft factory rubber bushings. Our kit replaces the factory links commonly referred to as the rear wishbone and rear guide links.

Our links feature black anodized and gundrilled 2024 aluminum links, 6061 aluminum clamps, titanium socket head cap screws, tapered stainless steel knuckle mount spacers and FK rod ends. This combination provides superior performance, durability, and ease of adjustment. Long gone are the days of fumbling with wrenches to tighten jam nuts while trying to trying to keep your bearings orientated correctly.

Sold as a set of 4 arms.

Black Anodized and Gundrilled 2024 Aluminum Links
6061 Aluminum Rotating Clamps allow for a wider range of adjustment vs jam nuts
Titanium Socket Head Cap Screws
Tapered Stainless Steel Knuckle Mount Spacers
Low Friction 3 Piece Teflon Lined FK Rod Ends
Made in the USA
Applications:

2014+ F80 M3

2014+ F82 and F83 M4




SPL Front Lower Control Arms F8X - Race Version

SPL front lower control arms provide roll center, camber and track width adjustment for the F8X M3 and M4 BMWs and allow for full articulation with the correct ball joint angle. 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 orientated correctly. The main arm is slotted to allow the use of pinch bolts and our rotating clamps on our exclusive hybrid adjuster lock down camber and track width settings. Our hybrid double adjuster is machined from 4130 chromoly and is 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 race version DOES NOT include the headlight adjusting rod.

SPL Billet Lower Control/Trailing Arms Feature:
• Lightweight Aluminum, Titanium, Chromoly and Stainless Steel construction
• Correct ball joint angle for full articulation
• Clamp design allows for easy access to lock down your alignment settings
• Low friction 3 piece Teflon lined FK sphericals and Heim joints/rod ends
• Multiple size stainless steel roll center spacers for precise adjustment
• Made in the USA

Sold as a pair.

Applications:

2014+ F80 M3

2014+ F82 and F83 M4

SPL TITANIUM series tension rods 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 characteristics can also be tuned with the use of our stainless steel spacers

SPL 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.

Note on Three Piece FK Bearings: These rod ends are manufactured in Connecticut and feature 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.

Sold as a pair.

Made in the USA.

SPL PRO Rear Endlinks F8X BMW

SPL PRO rear endlinks for the BMW F8X chassis feature massive Teflon lined FK 1/2" bearings to provide the highest load capacity for use with stiffer aftermarket sway bars. Custom heat treated chromoly high misalignment studs connect to the sway bar and offer extreme articulation capability (65deg) to prevent the endlink from binding when used with different adjustment holes on aftermarket sway bars.

SPL end links are length adjustable to eliminate preload on the sway bars, which can result from uneven settling of springs or uneven suspension heights from corner weighting. Black anodized 6061 aluminum turnbuckles work in conjunction with the left and right hand threaded rod ends for simple and precise adjustment. These end links are perfect for street or race applications.

Sold as a pair.

Made in the USA.

Application:

2014+ F80 M3

2014+ F82 and F83 M4

2015+ F87 M2

SPL Eccentric Lockout Kit BMW F8X M3 M4

The stock eccentric bolts provided by BMW for small toe adjustments tend to slip under high cornering loads, causing changes to the rear alignment. Our SPL eccentric lockout kit eliminate the stock eccentric bolts to keep your rear alignment where you set it. You must have adjustable control arms in order to adjust toe after eliminating the stock eccentric bolts. Our lockout plates are CNC machined from 6061 Aluminum and supplied with CAD plated grade 10.9 hardware for absolutely zero-slip. Kit includes washers and bolts for both toe arms.

Good upgrade for your SPL toe arms or other brand toe arms without the eccentric lockout feature.

Sold as complete kit for one car.

Made in the USA.

Application List:

2014+ F80 M3

2014+ F82 and F83 M4
