Ohlins DFV rear preload settings
#11
Everyone does that. Its a very short stroke damper. Honda has been doing that on stock suspensions for a long time.
If you can get some extra travel before touching bumpstop, it may be useful. Definitely not critical.
Food for thought....a 1" drop (measured at the wheel) with Konis or stock shocks would result in about the same space before bumpstop.
The Öhlins (because they are full body adjustable) are going to be compression travel limited - just like all full body shocks. BUT...the travel room doesn't change unless you change the preload. That's their give and take.

Yep, I had the same issue with my Konis. I run about a 3/4" drop in the rear, plus I cut the bump stop and trimmed the shock sleeve. The difference with the Konis, is they seemed to have more total travel to work with. However they also did not have a length adjuster either.

I'm at 2mm preload. My car weighs like...100-140ish LBs less than stock.
My rear shocks/springs compress 1.53" at static ride height. Car glides over stuff, is quick on track. I can feel bumpstops every now and then. My street damper settings are 11/11.
Always set preload BEFORE installing.

I set the spring to 198mm out of the car.
When the car is on the ground, I can crawl under it. It has a single exhaust...and I have the physique of the main pirate from Captain Phillips.
I measure the spring length to be 159mm with the car's weight.
(198-159)/25.4 = 1.53"

What is the rear shock angle (from imaginary vertical) when the LCA is horizontal?
If my shock angle is around 15deg (from imaginary vertical) at my ride height, then 1.53 works. I'll measure the angle when I have a chance.
I think my car weighs like 2660-2700LB.
So like 670LB per corner maybe.
670 x (cos15) = 680.
680/447 = 1.52.
Close enough to reflect my measurement.
**there are error margins in the unknown since I'm assuming all the weight is sprung (it's not), and that I clocked the bushings perfectly to static height.

Since you're setting yours up anyway....try 13.25mm (just 13mm is fine lol) of total rear preload. That should give you 1" of free space before bumpstop.
I figured 700LB force on each rear shock for a 100% full weight car (no driver).
LMK how it works if you try it out.
