Consists of four Black-Art Design coil-over adjustable height / adjustable dampers (22 position / emulsified gas upgrade / high speed valving) , two 2½" Eibach springs (front), two 2¼" Eibach springs (rear), C spanner and plastic dirt shields. Several years of development have produced the perfect road / track / 'Ring spec suspension set up. Compliant, but with vastly improved roll control over Konis. An exceptionally good compromise for track day AND road use. Please note that this set-up has been designed for use with ROAD tyres. The use of slicks would ideally require stiffer springs. Helper springs are a £180 cost option (set of 4 with required dual spring seats). Delivery inside UK is £20.
