I'd say there's no need for them so performance wise, just your call if you're willing to endure the harsher ride for the sake of not having to replace bushes all the time. @[Venom] is running JOMs with BMW bushes and iirc he had to replace them a couple of times in a short enough space of time, maybe he can give more feedback on what it'd be like with coilovers and original bushes.
