You can get them from Ohlins. Ours came with 400lb/in. But they are too stiff for proper FSAE use.

hey Rex we were looking for a used one. Anyway thanx for d info regarding ur experience. wanna no if anything with stiffness greater than 250 lbs/in will actually help eliminate Anti Roll Bar??

Sorry - suspension is not my area of expertise, though running stiff springs seems like a strange way of enabling you to get rid of a part. You don't *have* to have an ARB on your car. Most FSAE cars seem to run fairly soft springs, so there's probably a good reason for that.

yeah we run 500lbs/in with no anti roll bar and it is still too soft so would recommend keeping it. bell crank ratio obviously effects it, but ours seems to be in the ball park with what other teams use
