Techna-Fit stainless steel braided clutch lines for the 06-10 Honda Civic Si are manufactured to DOT specifications. The stainless steel construction eliminates 'ballooning' associated with stock rubber lines. This upgrade will result in crisper shifts and more consistent clutch engagement and pedal feel. As 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.
