TAMIYA Hotshot Series Front Lower Suspension Arms (Aluminium) - JR-THS06-GU for tuning by Jazrider  [JR-THS06-GU]

Performance and tuning notes

The JR-THS06-GU aluminium front lower suspension arms are an aftermarket replacement from JAZRIDER for use with TAMIYA Hotshot, Hotshot II/2 and Boomerang 4WD chassis. Fitting aluminium arms in place of the stock plastic items gives a firmer front end that helps maintain suspension geometry under load and supports more consistent handling.

This part is compatible only with the models listed and is supplied for hobby use. When installing, do a trial fit to check hinge-pin alignment and ball-stud positioning, examine existing bearings and pins for wear, and confirm there is no binding through full travel. Small deburring or paint removal on mating surfaces can improve fitment.

In tuning terms, the reduced flex of aluminium arms often sharpens turn-in and stabilises camber under cornering loads. Because the front end becomes more rigid, expect to re-evaluate related suspension settings such as roll center and anti-squat to keep balance across the chassis.

These aluminium arms are suited to racers and tuners wanting a firmer front end and more predictable steering, while keeping the original chassis geometry intact.
