GR/VA/BRZ Super 8.8 Rear Frame

TSSFAB Super 8.8 Rear Subframe – GR / VA / BRZ / FRS / GR86 2012 to 2025

The new TSSFAB rear frame is built from Strenx 100 plate and Docol R8 tubing for maximum strength and minimal flex. Every mounting point has been corrected 15 mm upward, improving CV angles and geometry on lowered cars.

In order to install this frame the charcoal canister and emissions parts that sit above the rear subframe must be removed. This frame is for offroad and track use only.

Trailing Arm Geometry
The trailing arm pickup is longer and lower, giving better squat control and rear grip under load.

Toe Link System
Revised Toe Link Design: Longer toe links combined with multiple toe-mount options allow fine control of toe-in gain and rear stability under load — from drift to grip.

Sway Bar Mounting
The sway bar has been raised 1 inch in the chassis to eliminate linkage bind and keep proper motion ratio through the full suspension range.

Cone Washer & Socket Mount System
Features machined cone washers and socket-style locating mounts that precisely center the frame to the chassis.
This system greatly increases chassis stiffness.
