Alignment is crucial to the handling of your vehicle. Remembering that the only thing that touches the ground is your “Contact Patch” of your tires you have to make sure that your tires and wheels are doing exactly what you want. With this you must make sure you have the proper camber, caster and toe as well as make sure they are all working together and not against each other.

The 350Z/370Z is sensitive and “picky” when it comes to the way it responds to alignment characteristics. The way that the rear suspension is setup is pretty complicated when it comes down to adjustments being made. And all the soft bushings on the end of each arm that are designed for comfort can really give the car a sloppy feeling in the rear.

For those who utilize an aftermarket Coil-Over system that REMOVES THE USE OF THE OEM SPRING PERCH, Megan Racing has developed an adjustable rear lower control arm that replaces the large heavy aluminum spring perch and it’s soft bushings and replaced them with a powder-coated steel arm that has length adjustment and pillow-ball ends to remove any play in the suspension. The Powder-coated Steel Construction also adds for durability and wear against demanding competitive conditions and rough driving surfaces as well.

All of the suspension components are affected when lowering the car, especially when lowered to the extreme. Correctly modifying the suspension pick up points or knuckles to correct for these changes can reap large rewards, including better camber and toe curves, less body roll for a given spring rate/anti-roll bar, and more traction/grip.

-WILL NOT WORK WITH OEM SUSPENSION OR SUSPENSION SYSTEMS THAT REQUIRE THE USE OF THE OEM REAR SPRING PERCH!!!

-Requires use of TRUE Coil-Over suspension in the rear (will not work if springs and shock are separated – this arm eliminates the spring bucket arm).

-Allows adjustment of Rear Toe and track width.

-Powder-coated for durability against the elements.

-High Strength steel construction protects against stresses of competition.

NOTE: Typically when the chassis is lowered, and camber is reduced, toe in adjustment becomes limited and will remain limited unless these rear lower arms are changed as well (MRC-NS-0321), instead of only replacing the camber arms (MRC-NS-0310) and the rear radius arms (MRC-NS-0370). This requires a true-coilover setup to replace the spring-bucket which is the limitation. Some toe adjustment may be done without the Adjustable Rear Lower Arms if the eccentric bolt is retained on the spring bucket arm, however that has its caveats with the retention of the eccentric bolts instead of replacing them with lockout bolts.
