AST astAST-140-70-61

The AST linear race spring is a single 140mm coilover spring with a 70 N/mm rate and a 61mm inner diameter. Its linear characteristic keeps the spring rate consistent through travel, delivering predictable response for suspension tuning and ride-height control on coilover-equipped cars. Supplied individually, this spring from AST’s Linear Race series supports accurate corner-weighting and fine-tuned handling.
