Core RC Hi Response TC Spring 2.2-2.9 Brown

The Core RC Hi Response TC Spring 2.2–2.9 Brown (SCH-CR848) is a progressive-rate 19 mm suspension spring for 1/10th touring and FWD cars. Developed by Schumacher engineers and high-level drivers, it is designed to improve chassis responsiveness on on-road tracks.

Key Features

• Progressive spring rate: 2.2–2.9 N/mm, Brown colour code
• 19 mm length suited to 1/10th touring and FWD platforms
• Fewer coils and thinner wire for sharper handling response
• Over 40% weight saving versus many competing springs; approximately 5.2 g per set of four
• Part of the Core RC Hi Response range, which spans linear rates from 1.9 to 3.5 N/mm alongside this progressive option

By reducing coil count and wire diameter, the Hi Response design lowers mass and inertia, helping the car react more quickly to steering and surface inputs. This spring provides a smooth, progressive feel that supports front-end grip, balance and stability during corner entry and exit.

Ideal for fine-tuning on-road suspension setups, the SCH-CR848 progressive Brown option integrates naturally into established touring car spring choices while delivering a more agile, responsive drive.
