If you’ve spent any time at track days or scrolling through high-end build threads, you’ve seen the distinctive blue-anodized hardware and clean billet lines of SPL Parts. But beyond the "car porn" aesthetics lies some of the most advanced suspension technology available for the modern enthusiast.
At Elite Performance, we specialize in high-performance platforms like the BMW M-Series, Porsche, and the GR Supra. When we’re looking to shave seconds off a lap time or eliminate vague steering feel, SPL is our first choice. Here is why SPL Parts are the "gold standard" for suspension geometry.
Beyond the Rubber: The Power of Spherical Bearings
Factory suspension arms use rubber bushings. While great for soaking up potholes on your commute, rubber is the enemy of performance. Under hard cornering or heavy braking, rubber bushings deflect, causing your alignment to shift dynamically. This results in a "vague" feeling in the steering wheel and inconsistent handling.
SPL Parts replace these mushy bushings with FK PTFE-lined spherical bearings. These allow the suspension to articulate freely without the unwanted "slop" of rubber. The result? Laser-precise feedback and a car that goes exactly where you point it.
Geometry Correction for Lowered Cars
When you lower your car with coilovers or springs, you inadvertently mess up your suspension geometry. This often leads to "bump steer", where your car steers itself when hitting a bump, and a compromised roll center.
Key Solutions from SPL:
- Bumpsteer Adjustable Tie Rod Ends: These allow you to relocate the tie rod pivot point, ensuring your toe stays consistent even as the suspension compresses.
- Roll Center Correction: SPL’s Lower Control Arms feature shims and spacers to bring your roll center back into the ideal window, reducing body roll without needing excessively stiff (and uncomfortable) springs.
Infinite Adjustability
Most OEM cars offer very limited alignment adjustment. If you’ve added wider tires or more aero, the factory "green zone" alignment simply won't cut it. SPL arms provide a massive range of adjustment for:
- Camber: Maximize your tire contact patch mid-corner.
- Caster: Improve straight-line stability and steering "self-centering" torque.
- Toe: Dial in the perfect rear-end stability for high-speed sweepers.
Lightweight & Robust Construction
Unsprung weight is the enemy of a fast suspension. SPL Parts are CNC-machined from 6061-T6 Billet Aluminum, making them significantly lighter than cast-iron OEM counterparts. Additionally, they use Blue Anodized Titanium hardware and Grade 10.9 fasteners to ensure that once your alignment is locked in, it stays there, no matter how many curbs you jump at the track.
