SPC Performance Alignment Camber / Toe Shim Assortment
SPC Performance Camber & Toe Shim Assortments: Precision Alignment Made Simple
When a vehicle's rear suspension drifts out of spec — whether from worn bushings, a lowering modification, or normal settling — correcting both camber and toe simultaneously used to mean stacking multiple components or investing in expensive adjustable arms. SPC Performance changed that equation with their purpose-engineered Alignment Camber / Toe Shim Assortments, offering a streamlined, shop-proven solution for restoring proper geometry on a wide range of passenger vehicles.
The EZ Shim: A Patented Dual-Angle Approach
At the heart of SPC Performance's shim lineup is their signature EZ Shim — a patented Full Contact Dual Angle Shim design that corrects both toe and camber with a single shim. Rather than requiring separate components for each angle, the two-piece adjustable design lets technicians and DIYers dial in precise corrections using just four part numbers that span a broad range of rear shimable front-wheel-drive vehicles.
The geometry behind the EZ Shim is what sets it apart. Proven adjustment changes are within 0.03 degrees of toe and 0.10 degrees of camber, giving shops and enthusiasts confidence that the correction they set on the bench will translate accurately to real-world alignment readings. Each shim package includes an instruction sheet, and SPC backs the system with a 75910 Dial Chart and an online EZ Shim calculator to make selecting the correct orientation straightforward.
Assortment Kits for Maximum Versatility
SPC's assortment approach means that rather than hunting down individual shims one at a time, a single kit provides the range needed to address most common correction scenarios. Fixed-change shim kits — such as those designed for popular platforms like the Honda Fit — include multiple pairs covering toe adjustments from -0.5° to +0.5° in 1/10° increments and camber adjustments from ±0.25° to ±1.0° in 1/4° increments. Technicians can combine up to two shims to fine-tune both angles simultaneously, eliminating guesswork and reducing alignment chair time.
Why SPC Performance Stands Out
SPC Performance — a division of Specialty Products Company based in Longmont, Colorado — has built its reputation as one of the automotive industry's foremost alignment specialists. Their shim products are engineered to install without vehicle modifications, and their broad application coverage makes them a go-to for both independent shops and serious DIY enthusiasts. The EZ Shim system's durable construction and patented full-contact design ensure the shim seats securely against the hub flange, reducing the chance of migration or slippage over time.
