SPL adjustable Rear Lower Camber Arms (RLL) for the GR86/BRZ/WRX allow for adjustable camber, track, and installed motion ratios while significantly reducing the unwanted dynamic alignment change and binding that occurs with rubber or polyurethane bushings. The lower arm also handles the forces transmitted through the springs, shocks, and sway bar. By increasing the strength (rigidity) of the arm and using a spherical the rear suspension will have improved response, better lateral grip, and provide clearer feedback to the driver.

Adjustable Motion Ratios: The three position mounting holes for the sway bar endlinks and shock mount allow you to adjust the mounting points to prevent endlink binding and quickly adjust motion ratios to change spring and sway bar effectiveness. Simply put, it's like having adjustable spring rates without a spring replacement. For example, a 6.0 kg/mm (336 lbs/in) main spring could act as a 6.8 (380 lbs/in), 6.0, or 5.2 kg/mm (294 lbs/in) spring, giving +/- 13% of adjustability. Likewise the sway bar endlink can be installed to act like a 0.5mm larger or smaller bar, so an 18mm bar would act like an 18.5mm, 18.0mm, or 17.5mm bar depending on setup (endlink geometry permitting).

Unrivaled Adjustability Range: The large-diameter chromoly double adjuster and 5/8" (15.8mm) rod end allows for up to 1.375" (35mm) of total length adjustment, a 50% increase compared to many other options on the market.

Easy, On-Car Adjustments: Instead of jam nuts, the SPL rear lower arms feature 360 clamps and an electroless nickel plated double adjuster to make setting the camber angle significantly easier. Simply loosen the 1/4"-20 titanium hardware and turn the double adjuster to achieve the desired amount of camber. Lastly, tighten the 1/4"-20 titanium hardware to lock it in. No more wandering alignment specs as you try to hold one end and tighten the other.

Noise, Vibration, and Harshness (NVH): The rear lower control arm is not a significant source of percieved NVH. In fact, it's more and more common for OEMs to use sphericals in the knuckle bushing where the lower control arm mounts. The spherical rod end eliminates torsional bushing bind, resulting in a small improvement to ride quality, but may transmit a small amount of additional road noise over textured/grooved pavement.

Sold as a pair. One pair per vehicle.

Replaces OEM Part Numbers: This is a list of known OEM part numbers. OEMs constantly make changes to part numbers due to part updates, suppliers, etc so this may not be a complete list.(Toyota-SU003-08417,SU003-04490),(Subaru-20250-AL011,20250-FG042,20250-AJ040,20250-CA010)

Customer photo review of Racer X Fabrication GR Corolla Lateral Shift Linkage

A must have upgrade for your GR Corolla. This unit eliminates the side to side play that the factory shift linkage has. Nice, tight shifting post install. Awesome upgrade 👌🏼

Customer photo review of Ghost Ride The Whip Tee

The background print is too dark. The outline of the trees cannot be seen. The tombstones are very dark and the names on them cannot be seen. Cannot see the wheels or grill.

Customer photo review of Ice Cap Rolla Tee

Ordered an ice cap tee. No idea how a chose a small for my dad bod but my mistake was my daughter's gain. She immediately stole the shirt because we work on the car together. The Grey color is perfect for the colors in the design and makes the red pop. The design is sick and the quality shirt is really really nice. So much so I ordered the right size immediately! Buy one!

Customer photo review of OneSix Dad Hat

This hat…what can I say? Do you want to be the talk of the GR community? Do you want to have people look at you and know you mean business? Do you want keep the sun out of your eyes (wearing it forward of course)? Do you want to be successful? If you answered yes to any of these, then this is the hat for you! The fit and feel of this hat is perfect, much like the Brin Naub® and synthetic leather-trimmed sport seats in the GR. The embroidery seems as though it was done by the hands of angels, every stitch to perfection. When I first put this hat on, I lost 15lbs and gained another 15lbs in muscle (can’t confirm it scientifically, but the scale stayed the same and I felt stronger). My senses while having this hat on were also heightened. The 6 speed manual transmission in my GR Corolla didn’t stand a chance as I flew through the gears masterfully while passing the Ferrari SF90 stradale awd that couldn’t keep up with me (it may have been slowing down to turn, but pretty positive they saw me and knew they couldn’t keep up). Bottom line is, you want this hat, you NEED this hat. I’d recommend buying atleast two of them for when people notice you’ve become too powerful and try to steal your hat. Always have a backup! And remember, with a great hat comes great responsibility, or something like that. Buy this hat now!

Love the design of the shirt!! I ordered two of them and they were delivered quickly after. My family loves this shirt as I have a HM GRC. Next time, when I order again, I’d consider getting one size larger.

Customer photo review of Hyouyuki ヒョウユキ | Drifting Snow Tee

Graphics are sick, they’re printed well (screenprinting feels thick, like it won’t crack, fade or peel so that’s good) printing seems accurate (back is perfectly centered), blank material is always s tier w comfort colors so that’s good. 10/10 will buy again

Hyouyuki ヒョウユキ | Drifting Snow Tee

Going to make this short and sweet, was going to order my MBRP exhaust through a different company but before that I had onesix In the back of my head. The experience I had was top tier. They answered every single question and kept me in the loop with shipping. I would definitely recommend buying from these guys! They're in it to make sure the customers that buy from them are more then satisfied...but well taken care of.
