Guess its how you drive it, but for high speed sections I wouldn't want anything softer then the normal shock, in fact I'm hoping when I have mine rebuilt they can add some more high speed compression to the shock.
Are the 9000s remote reservoir? If not I feel like I'd overheat them fairly quickly. Was thinking foxs, kings, or RR bilsteins. Which are obviously way more expensive. For what I want to do I was wondering if the 9000 was a cheaper alternative, but sounds like they are too soft.
