I have finally made some progress,
spoke w/ Bilstein, they can't divulge b6 specs because it's Porsche proprietary property

but they were willing to share b8 inserts specs

I need to follow up as there may be a typo or slip of the typist(wink, wink)
The gave me the insert specs for

Bilstein b8 cartridge #34-050507
collapsed length 14.33 in
extended length 21.36 in

Bilstein b8 cartridge #34-001134
collapsed length 17.09 in
extended length 24.67 in

I think that you can see why there may have been a slip up here

anyone w/ b6 inserts laying around care to measure?

would love the compressive force too

From this pic it looks like the MC is ~3" shorter that the b6 you removed, about the same as a b8 insert would shorten the strut


If so, that changes the raised spindle calculation, because it places the stock spindle and steering in the same place on a 3" lowered 911 as the stock b6 would place them at stock ride height.

i.e. raised spindle isn't necessary

the relation goes like this

shorten the strut 1" is the same as raising the spindle and steering 1'

Bill, I’m genuinely a bit worried about that. Put it all back together today for most part once I can sort out spring plate covers. The MCS sits noticeably higher at droop.

I had to play around with the front ride height enough to relieve tension on A arm so I could jack shock into strut housing. Otherwise I’d measure TC to wheel hub for a proper A v B.

This shock length thing is something that i've been looking at for the past few years, There's been very little discussion or been there done that advice.

It also explains something that I've known but hadn't thought about wrt to my 993 track car and a few others that I'm very familiar w/. There are all pretty hardcore very low track cars w/ in my case Bilstein Cup shocks and others w/ Moton shocks, all of these shocks are ~ 3" shorter than the street Bilstein/Monroe, Boge shocks. We all have 993 RS wheel carriers or aftermarket equivalents that raise spindle height.

All of these cars exhibiting outstanding steering and handling due to the combination of raised spindle, which I knew about, and shorter shocks, which I hadn't really considered.

This is eye opening to me.

I've mentioned short throw shocks to you before Bill as I've been running them on a SWB for years. No raised spindles but bump kit. Some poly and ER rubber in the front. Perhaps PeteK will chime in as a 'neutral' as he's driven it. Sadly my MFI pump is still away so I can't comment on the new rear bushings. The V2's did make a difference over the old Bil's I had. Car is low and handles about as flat as you could ask. Enough so that I can tell the difference with the fuel load.

so what is the extended length of your struts or inserts?

That you will have to wait for until the motor is back in. I can tell you off the top of my head the front is 22" from ground to fender lip. Inserts. There is a trick for that I've mentioned in the past.

I've been busy with other projects the past few days, so just getting to this thread. Yes, his car does stay very flat in corners, however, it's also very stiff over bumps. It also sits very low, as 22" at the front fenders would suggest. The Vons shocks should ameliorate the street stiffness somewhat, but we won't know until he gets his engine back into the car and we can drive it. Once the car is back together, we can figure out how much travel the shocks have before hitting the bump stops.
