Coilover Spring 12in x 2.5in 150/400 Prog 120-250-400V

Progressive coilover springs deliver the responsive handling and tunable suspension geometry that serious racers and track-focused builders demand. This kit's dual-rate design—150 lb/in initial, 400 lb/in final—allows you to dial in compliance during initial suspension travel while maintaining composure under cornering loads and acceleration. Whether you're fine-tuning a road course setup or building a dedicated drift machine, these coilovers give you the precision control that separates fast drivers from faster ones.
