If you are using a HPI body for your 1/10 scale on-road I would highly recommend these spoilers, made wide durable plastic, it will withstand your typical punishment better that what comes with the body and is adjustable, and what
i like about this kit is you can use it with bodies that have the molded post built in like the HPI Nissan Skyline R34 #7427 with the kits adapters for it.
