Default Ohlins DFV ... What about the front shocks?

So we have been discussing shock travel, ride height and preload issues with the rear dfv shocks because of their short travel. But what about the front shocks? With the provided 10k springs and 2mm of preload, how much clear piston bump travel is available? How much total piston travel is there? Is the 2mm preload spec the optimal balance between available compression and rebound travel? Is there any value to running a softer spring rate in the front similar to the ap1 factory spring rates?

Well....I will say thay its kinda hard to measure the static height spring compression up front unless you're on on alignment lift lol.

And unless you know the SPRUNG weight of your S2000, you won't get an accurate measurement via calculation.

I don't *quite* think 2mm is enough for "normal" roads. But you've got tons of room for adjustment up front.

I didn't even take measurements on the front piston travel when it was off the car. I don't even know how much total shock travel there is.

it seems to me you would want a compression to rebound travel ratio similar to the rear.

The stock suspension has quite a bit more rebound travel than compression travel.

About 1" of front compression travel and 2" of rebound.

About 1" - 7/8" of rear compression travel and between 2.25 and 2.38" of rebound.

Ratio of 2:1 or better REB:COMP.

I think that finding the "right" setting on a modified suspension involves driving and experimentation.

Be cause of the limitations in the rear with Ohlins, I would think you would be looking at 1:1 or 1.2:1. But not 2:1.

Precisely right. Theory is great until you test and realize something doesn't work at all. The right amount of rebound travel is just as important as compression travel.
