Xray 4S 2.8 touring car spring set
Xray have added a new spring to their range of 20mm low-profile 4S springs in the form of the C=2.8. The second hardest in the range fits between the 2.9 and 2.7 and it each set is individually controlled, measured and matched for best possible consistency. The black-colour springs come in sets of two and they are marked for easy identification.
