SPC Performance Alignment Camber & Toe Kits: Engineering Meets Precision
When a vehicle is lowered on coilovers, lifted for off-road duty, or simply pushed hard on a track, factory suspension geometry rarely stays within spec. Camber goes negative, toe wanders out of range, and tire wear suffers. This is exactly the problem that SPC Performance has spent decades solving — and their Alignment Camber / Toe Kits represent some of the most thoughtfully engineered solutions in the aftermarket.
Specialty Products Company (SPC) is the world leader in the development, manufacturing, and sales of wheel alignment parts, with the SPC Performance brand specifically targeting off-road, track, and enthusiast markets. Founded in 1971 , the company has built its reputation on one thing: making alignment adjustable where the factory never intended it to be.
What Makes SPC Camber & Toe Kits Different
SPC Performance doesn't just make adjustable arms — they engineer systems. A standout feature across their camber and toe kit lineup is the proprietary xAxis Sealed Joint. These xAxis sealed flex joints perform like monoballs but use non-metal bushings, and when combined with forged steel receivers and straight-arm construction, they minimize compliance under load. That means race-day precision without the harshness or noise of a traditional pillow-ball setup.
Another differentiator is SPC's approach to toe adjustment. SPC's control arm is the only kit on the market to include an offset toe bushing to increase the range of the factory toe cam. This matters enormously for enthusiasts who need to correct both camber and toe simultaneously after a suspension modification — something that most competing kits simply cannot address in a single install.
Broad Vehicle Coverage & Generous Adjustment Ranges
SPC Performance camber and toe kits cover a wide range of popular sport and performance platforms. Their kits for the Subaru WRX, BRZ, Toyota GR86, and Scion FR-S deliver ±2.0° of camber adjustment alongside an offset toe bushing and xAxis sealed joint for precise alignment and improved handling. For Nissan and Infiniti enthusiasts, the race-ready kits for the 350Z and G35 dial in ±3° of camber and ±2° of toe, and include adjustable rear lower control arms, camber lockout plates, and extended-range toe cams.
These kits are especially well-suited for anyone who lowers their vehicle 1 inch or more and needs to correct camber problems while keeping toe in proper adjustment. SPC Performance rear camber and toe adjustment kits can double the range of rear camber and toe adjustment to increase handling performance while minimizing tire wear.
Race-Proven, Street-Ready
Motorsports can be hard on suspension components, and SPC parts are engineered to withstand that punishment — if they can survive competition, they are more than capable for daily-driven commuter vehicles. SPC sponsors Papadakis Racing, the most winning drift team in history, with an unmatched record of five Formula Drift Championship titles.
Founded in 1971, SPC has developed patented products like the EZ Cam and EZ Cam XR adjustable cam bolts, with camber and caster parts designed and tested in the USA to meet or exceed factory standards. SPC is proud to be an ISO 9001 & IATF 16949 certified company , underscoring their commitment to quality in every kit they produce.
