These aluminum rear suspension arms are produced as a direct-fit option for the Tamiya TA07 and TB04 Pro II touring car platforms, presented in a gun metal anodized finish to combine strength with a subtle aesthetic.
Swapping to aluminum alters the chassis flex balance and can make rear roll and camber behaviour more predictable under braking and cornering. Many tuners select aluminum arms when seeking repeatable handling while experimenting with spring rates and anti-roll adjustments.
Fitting advice: replace the stock rear arms at the existing pick points and confirm that servo travel, motor clearance and drivetrain components do not contact the new arms. Re-torque fasteners after initial testing and replace any fatigued ball studs or screws.
