The 3Racing SAK-D627 rear bulkhead lower stiffener is a targeted chassis brace for the Sakura D6 Sport. It strengthens the rear mounting area to limit bending under acceleration and cornering, helping the suspension maintain its intended geometry.
Reinforcing the rear reduces unpredictable flex and helps the car respond more linearly to steering and throttle inputs. This makes it easier to dial in consistent lap times and feel during aggressive driving sessions.
Purpose-fit for the Sakura D6 series, the stiffener bolts into existing points on the chassis so you can upgrade without cutting or altering the frame. It is a practical step for hobbyists upgrading handling without major rebuilds.
