Overview

Show original supplier description
The Megan Racing Rear Radius Arms are engineered to enhance the performance and alignment of the 2003-08 Nissan 350Z and Infiniti G35. When a vehicle is lowered, the rear toe and camber are significantly affected, impacting handling. These arms provide a solution by allowing a wider range of rear caster adjustment, which helps to properly tune the machine for performance and minimize rear wheel hop during acceleration and braking. Constructed from high-strength steel with a durable powder-coat finish, these radius arms are built to withstand the stresses of competitive driving and demanding surfaces. Key specifications include an inner eye bolt ID of 3/4" tapering to 15/16" with a 1 5/8" rod end width, and an outer bolt-hole ID of 1/2" with a 1 5/8" width. The outer end features M16x1.50 thread pitch. It is important to note that Megan Racing does not recommend making toe changes solely with these arms. Adjusting toe when lowered and with reduced camber can be limited unless the rear lower arms are also modified (e.g., with part # MRC-NS-0321), which may require a true coilover setup to replace the spring bucket. While some toe adjustment might be possible if the eccentric bolt on the spring bucket arm is retained, this comes with its own caveats.
