Kyosho MZW401 Front Spring Set MR-03

Kyosho MZW401 is a front spring set for the MR-03, supplying five springs across a range of rates so you can adjust front suspension firmness to suit the track.

A softer front spring lets the nose load up and generate more front grip, which helps a car that is reluctant to turn in. A firmer spring keeps the front end flatter and more stable, which suits high-grip surfaces or a chassis that feels vague. Because a Mini-Z is so light, the difference between adjacent rates in this set is easy to feel from the very first run.

Having the full range on hand means front-end tuning becomes a five-minute swap instead of a guess.
