This new cool looking purple alloy spring hanger for the SupaStox allows you to use smaller rear tyres yet retain the correct ride height and droop adjustment.
Typically with tyres below 46/45mm in diameter it has always been difficult to maintain the correct droop level for the car to have peak performance.
Now with this part you can use tyres right down to the smallest of diameters!
For best performance on regular carpet tracks we recommend 3.5mm of ride height and 2mm of droop. Droop is adjusted using differing thickness washers on top of the nut which secures the spring assembly screw to the chassis.
