This is a roll center nitro handling kit. This is one of the least known but most impactful upgrades you can get for the RS4 Nitro 1 and 2. This upgrade instantly changes handling characteristics and greatly reduces body roll in the corners.

These plates sandwich between the bulkhead and bottom chassis plate. The purpose of these is to support your suspension arms to keep them stable and flat in the corners. ( with addition of adjusting screws in the suspension arms you can adjust stiffness levels with just a 1.5mm driver) . Another benefit is it raises the whole top deck 3mm giving more room to run a bigger battery or for more flexibility in RX placement .

Thus upgrade was one of the best things about owning a Nitro Racer 2. This rare item can actually be added to ANY RS4 Nitro 1 and 2 RTR to convert to a Racer 2 or just to improve cornering.

These are lightly used and have scratches but are in good shape. They ship as you see them.
