SBG Billet Extended Lower Cup (S2000 Ohlins DFV Rear Ride Height Adjustment Kit) - SakeBomb Garage LLC

Just re-read this thread again. Apparently few people understand how to set these up as stock, let alone when changing to higher spring rates. Anyone that want's some guidance, PLEASE PM US... we have CAD all aspects of the S2000 suspension and geometry, as well as created a massive calculator which can get you to within 1mm of your desired ride height. Everything including spring rate, available stroke, motion ratio, internal shock pressure, ARB, desired ride height, preload, etc. must be factored in to set these up. Leave out a few variables and your setup is flawed. For some very high spring rates there is hardware required to go lower such as lowering cups, helper springs, etc. which may or may not be needed depending on your requirements. Each setup is unique which is why we help customers sort out each chassis specifically... there's no one size fits all specs here.

As a very short primer (though most of you already know this) as spring rate goes up, linear travel required decreases (as does drop/compression due to the chassis weight for static ride height). The effect is, the higher the spring rate the lower you need to adjust the shock in the lower cup for the same ride height. There are quite a few variables such as chassis weight, spring rate, optimal positive pre-load (or "negative" pre-load with a helper or assist spring). But as a rule of thumb, with high spring rates, you'll need something like our lower cup to get to the height most people expect for track use.
