Product Information

A pair of adjustable rear mid links that replace the factory spring bucket arms, with a threaded lower spring perch for setting rear ride height and corner weights. They give a wide range of rear toe adjustment, and PTFE-lined rod ends cut the toe change that rubber bushing deflection causes. Springs are not included: the links take 60 mm ID coilover springs chosen for the rear motion ratio, and they do not fit Infiniti models with 4-wheel Active Steer.

Which springs are needed?

  • 60 mm ID coilover springs with a rate suited to the rear motion ratio, from Swift, Eibach or another quality maker. SPL publishes a midlink spring calculator for choosing the rate.

How is ride height set?

  • By threading the lower spring perch up or down. Ride height moves about 1.7 times as much as the perch, so lowering the perch 1 in drops the car about 1.7 in.

Is anything else recommended?

  • The SPL eccentric lockout kit, which removes the factory eccentric bolt that can slip under load and also saves re-aligning the upper spring seat each time the eccentric is turned.
