Megan Racing Adjustable Rear Lower Arms - Nissan 350Z

The 350Z is the next generation of the Fair-lady, the Z33, and is Nissan s current dominating force in motor-sports. With it s Naturally Aspirated 3.5L Quad-Cam V6 (VQ35DE) that boasts torque from Low-Mid Range to Red-line the 350Z is an extremely well-adapted force in competition. In it s stock configuration it is capable of so much but is still watered-down from it s full potential due to the conservative restraints of Consumer marketing and comfort.

The 350Z is a heavy-machine weighing over 3,200lbs and is plagued by body roll and a soft spring-rate for the comfort of the masses. For this reason Megan Racing has decided to develop numerous products to enhance the performance and bring out the full potential of the 350Z/G35 on both the street and track.

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/G35 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.

Rear lower arms: Help determine roll center, anti-squat, and can affect camber. The angle front to rear of the control arm (vertical plane) determines anti-squat (along with the angle of the camber arm and traction arm mounting points). The flatter the control arm, the more squat. S13’s have a lot of anti-squat, S14 and 15’s have significantly less. The angle side to side (horizontal plane) is what helps determine roll center.

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.

-Designed for 2003+ Nissan 350Z and Infiniti G35.


-Requires use of Coil-Over Shock suspension in the rear.

-Allows adjustment of Rear Camber 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 (MRS-NS-0321), instead of only replacing the camber arms (MRS-NS-0310) and the rear radius arms (MRS-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.
