Has anyone tried different length/durometer bumpstops on these?

I had a Miata with FatCatMotorsports coilovers (shortened and re-valved Bilsteins), and putting shorter progressive bumptops on made a dramatic difference in handling
- shorter (with the shorter shock body) = increased amount of compression travel
- progressive = smoother engagement instead of on/off like a longer/stiffer bumpstop

I guess you would need some video or a way of telling if the standard DFV bumpstops were actually being engaged with whatever type of driving you are doing.

Does anyone know how much piston travel there potentially is, and how much travel there is before the tophat hits the bumpstop?

I measured 0.6" of free travel on MY car in the rear, at Öhlins' 2mm recommendation. No driver. Full tank.

Free travel = travel before the tophat contacts bumpstop.

I am positive 110%, that the bumpstop is very active during street driving and that's part of the reason the suspension does NOT feel "more compliant than stock" unless your roads are very good.

On a smooth track, maybe its active...but not quite so much.

I have the car set lower than Öhlins recommends via lowering the bottom bracket like 10mm or so.

I refuse to raise the car beyond this. Because I'm not interested in using my S2000 as a rhinoceros safari access vehicle .




I should be able to get 0.8" free travel by adding preload, and still keep my ride height by lowering the bottom bracket.

If I mod the bottom bracket or shock threads, I can likely get 1" or so before running out of bottom bracket thread.

I haven't tried different bumpstops but as I recall the included ones are already progressive.
