SPL Parts 2013+ Subaru BRZ/Toyota 86 Front Lower Control Arms

SPL FLCA FRS Front Lower Control Arms for 2013+ Subaru BRZ / Toyota 86 / Scion FR-S

The SPL FLCA FRS Front Lower Control Arms are the definitive alignment solution for the Subaru BRZ, Toyota 86, Scion FR-S, and Toyota GR86 platform. This kit provides simultaneous adjustment of camber, caster, track width, roll center, and anti-dive geometry from a single arm, replacing the rigid OEM lower control arm and its bushing-loaded limitations. SPL Parts eliminated jam nuts entirely: a slotted arm body accepts the exclusive 4130 Chromoly Double Adjuster, and 360-degree rotating clamps lock settings with titanium allen screws. The result is repeatable, shop-friendly alignment changes without the frustration of spinning rod ends or slipping jam nuts. SPL FLCA FRS supports full-articulation ball joint geometry so the arm moves through its entire travel without binding, and stainless steel roll center spacers are included to correct roll center height on lowered cars. Whether used on a dedicated time-attack car or a lowered street build, SPL FLCA FRS transforms front-end handling precision.

Features and Benefits

• Five-axis adjustment: camber, caster, track width, roll center, and anti-dive from one arm
• 6061-T6 billet aluminum arm and trailing link with black anodized finish for strength and corrosion resistance
• 4130 Chromoly electroless nickel-plated Double Adjuster with gun-drilled weight reduction and 360-degree rotating clamp lock
• Low-friction 3-piece Teflon-lined FK sphericals and heim joints eliminate bushing deflection and binding under load
• Ti-6Al-4V titanium 1/4-20 socket-head allen screws reduce unsprung weight without compromising clamp force
• Stackable 304 stainless steel roll center spacers for precise, incremental correction
• Heat-treated 4130 Chromoly studs for long-term durability
• Increases achievable front camber from OEM 0 to -0.75 degrees to -2.5 to -4.0 degrees for proper cornering grip
• Enables 7.0 degrees or more of caster versus OEM 5.0 degrees for improved steering feedback and mid-corner grip
• Sold as a pair, made in the USA

Frequently Asked Questions

What camber range does the SPL FLCA FRS achieve on the Subaru BRZ and Toyota 86?
The SPL FLCA FRS enables front camber from approximately -2.5 to -4.0 degrees, compared to the OEM range of 0 to -0.75 degrees. Pairing with adjustable camber plates provides additional fine-tuning options.

Can the SPL FLCA FRS increase caster angle on my BRZ or FR-S?
Yes. The SPL FLCA FRS allows most setups to reach 7.0 degrees or more of front caster, compared to the OEM specification of approximately 5.0 degrees. Increased caster improves mid-corner grip, steering centering force, and camber gain during steering input.

Is the SPL FLCA FRS suitable for street use on a daily-driven BRZ?
Yes. The Teflon-lined FK sphericals are self-lubricating and self-cleaning, rated from -65 to 325 degrees F, and engineered for combined street and track duty. The SPL FLCA FRS is a practical upgrade for any lowered Subaru BRZ or Toyota 86 that needs proper front camber without eccentric bolt slippage.

Does installing the SPL FLCA FRS void my vehicle warranty?
Under the Magnuson-Moss Warranty Act, an automaker or dealer cannot void your vehicle warranty simply because you installed an aftermarket part. The dealer must demonstrate that the SPL FLCA FRS directly caused the specific failure being claimed. Unrelated warranty repairs remain covered.

Will the SPL FLCA FRS work with my aftermarket coilovers?
Yes. The SPL FLCA FRS is compatible with coilover setups and is particularly effective when combined with adjustable camber plates, allowing independent control of camber, caster, and track width.

Do I need to replace the roll center spacers for a stock-height car?
If your car is at stock ride height, install the SPL FLCA FRS without roll center spacers above the bearing to maintain OEM roll center geometry. Add spacers above the bearing only when the car is lowered to correct the roll center height. Do not exceed 1/2 inch of total roll center correction.

Does the SPL FLCA FRS fit the 2022+ Toyota GR86?
Yes. The SPL FLCA FRS fits the 2022+ Toyota GR86 (ZD8 chassis) in addition to the ZN6/ZC6 generation BRZ, FR-S, and 86 models.

What is the track width adjustment capability?
The SPL FLCA FRS allows the front track width to be extended to more closely match the rear track width, which reduces understeer tendency by more evenly distributing cornering load across all four tires.

Installation Overview

1. Raise and support the vehicle; remove front wheels.
2. Disconnect the sway bar end link from the lower control arm if required for clearance.
3. Remove the OEM front lower control arm ball joint nut and the subframe mounting bolt.
4. Separate the ball joint from the knuckle using a pry bar; remove the OEM arm.
5. Pre-set the SPL FLCA FRS to match OEM arm length using the Double Adjuster.
6. Determine the number of roll center spacers needed based on ride height; install spacers above the bearing only if lowered.
7. Install the arm at the subframe end first, then engage the ball joint stud into the knuckle.
8. Torque the subframe bolt to 100 Nm (74 ft-lb); torque the knuckle nut to 180 ft-lb using a calibrated torque wrench.
9. Lock the Double Adjuster clamps by torqueing the titanium allen screws.
10. Sweep the suspension through full travel to confirm no binding or contact.
11. Reinstall wheels, lower the vehicle, and perform a professional four-wheel alignment.
12. Re-check all fastener torques after the first 100 miles and 500 miles.
