STREET/TRACK APPLICATIONS (OCCASIONAL TRACK USE – CIRCUIT / TIME ATTACK / ROAD RACING)The Super Copper Kit brings a new level of performance to the street and track.It’s built with the highest copper content you’ll find in any organic clutch on the market — giving you a better grip than OEM, better heat tolerance, and more consistent performance on and off the track. Backed by a reinforced steel plate and a copper-loaded organic facing, it’s designed to hold more power without giving up smooth street drivability.This kit uses our reinforced steel-backed, copper-loaded organic disc paired with a heavy-duty single diaphragm pressure plate — delivering smooth engagement you can daily drive, and the grip you need when you push it. It’s the ideal setup for stock, tuned street cars and basic bolt-on builds that want more without giving up drivability.Like all of our sprung kits, the Super Copper features our patented fully enclosed spring retainer system — protecting you from failures that can cause serious transmission or engine damage, a problem we guarantee you’ll see with other brands.Every kit is hand-assembled and signed off after multiple quality checks by our senior engineering team (50+ years combined experience), making sure you’re getting real, tested performance — not guesswork.
