ISC Suspension Wheel Spacer
ISC Suspension Wheel Spacers: Precision Engineering Meets Perfect Fitment
ISC Suspension has built its reputation on engineering suspension components that perform at the highest levels — from daily streets to Formula Drift and Time Attack competition. Their wheel spacers carry that same engineering philosophy: meticulously designed, thoroughly tested, and built to last.
Hub-Centric Design and Premium Materials
What sets ISC Suspension wheel spacers apart from generic alternatives is their commitment to hub-centric construction. Each spacer is precision-CNC-machined from billet aluminum and is hub-centric for both the car and wheels , which means the spacer centers precisely on the hub rather than relying solely on the lug nuts for alignment. This reduces vibration and ensures a clean, balanced fitment.
ISC uses CNC 7075 lightweight high-grade aluminum for the spacer body, with Grade 10.9 hardware included. The 7075-series aluminum alloy is notably stronger than the more common 6061 alloy, making it a preferred choice for performance and safety-critical wheel components. The spacers are offered in an anodized ISC Black finish that not only looks sharp but also provides a layer of corrosion resistance. ISC also incorporates their Street Seal™ corrosion protectant technology on select applications for added long-term durability.
Sizes, Applications, and What's Included
ISC offers wheel spacers for various applications ranging from 3mm to 25mm, covering manufacturers like Subaru, BMW, Ford, Mazda, Nissan, Mitsubishi, Toyota, and Lexus. Their bolt-on hub-centric spacers are primarily offered in the same 15mm and 25mm sizes as the ISC Wheel Adapter line, and are made of the same quality material.
Each kit includes two precision-CNC-machined billet aluminum spacers and ten special low-profile, high-quality lug nuts — everything needed for a proper installation right out of the box. Sold in pairs, these ISC wheel spacers are a straightforward solution for those who want to run a direct-fit spacer application on their car.

When the same brand trusted on the race circuit designs your wheel spacers, you can have confidence in the quality of materials and tolerances involved.
ISC currently provides high-performance suspension kits, suspension components, and wheel accessories , meaning their wheel spacers are engineered to complement the rest of your suspension setup cohesively. Whether you're correcting wheel offset after a coilover drop, filling fender gaps for an aggressive stance, or improving track width for better cornering stability, ISC's hub-centric spacers are built to handle it.
