RC8 16mm Springs, 1.4mm Wire (front or rear)
Associated added these in July 2026. They are 66mm long and listed for both ends of the car, so the same spring works front or rear. The wire diameter is different from the other 16mm springs above, and that is the point of them — Associated says the feel is not something you can copy by running the same rate in their usual wire. Treat them as their own set rather than more rates for the tables above. On the rear you may need a second collar to get your ride height back.
