All Techna-Fit stainless steel braided clutch lines for the 02-05 WRX are manufactured to DOT specifications. The stainless steel construction eliminates 'ballooning' associated with stock rubber lines. This upgrade will result in crisp shifts and more consistent clutch engagement and pedal feel. Because installing a clutch line requires removing the slave cylinder, a stainless steel clutch line is the perfect supporting modification to a high performance clutch kit.
