Tomioka Racing Race coilover is specially designed for customers who demand better handling car when going to track and also require daily driving capability. The Race coilover features front inverted 1-way adjustable and rear 2-way adjustable rebound and compression with external reservoirs. It also combines the compression force in the high and low speed range to achieve the most efficient compression. The 15-level rebound and 10-level compression adjustments offer driver from comfortable to tighter ride with superior road gripping characteristic. All Tomioka Racing coilover includes high quality aluminum pillowball upper plate and rebuildable with 18-months limited warranty.

Compression Adjuster Circuit

Major components of the compression adjustment circuit are the slow bleed orifice, piston and shim cage. All these components work in conjunction to achieve the low and high speed compression on the race coilover. At low speed compression, the damper fluid is monitored through the slow bleed orifice in which pressure loss across the orifice results in opposing damping force. During high speed compression where the damping fluid travels at higher velocity, the slow bleed orifice creates too much resistance for the fluid. The extra force generated from the high speed fluid is handled by the piston and shim cage while still monitored by the slow-bleed orifice. The piston and shim cage virtually bypass the orifice during high- speed compression.
