For racers aiming to tighten rear-end behaviour, the Serpent 600890 Carbon Rear Upper Wishbone Inserts offer a focused upgrade for the SRX8. They are designed to let you adjust suspension geometry with greater consistency.
Using carbon inserts increases stiffness at critical mounting points while avoiding unnecessary mass. That helps the SRX8 resist deformation during aggressive cornering and improves feedback through the rear end.
These inserts match the SRX8 rear upper wishbone locations for a precise, repeatable fit. Consistent placement makes it easier to compare setup changes run to run.
Fit the Serpent 600890 inserts on a secure work surface using standard hand tools. Remove the existing components, install the carbon inserts, then recheck fastener torque and wheel alignment before running the car.
