Great info. I should wait to write this because I am rushing off to kid's practice. I spent some quality time on your web site today. You've put up some great stuff with fantastic insight and very well thought out and articulated positions. I look forward to spending more time there. Only wish I lived more proximate to you.
Great stuff!

thanks chaps
just a quick note to say that also on the front you do not need spacer number 18, certainly not with PSS10 as the spindle length between the top and the collar is not long enough to get through the spacer and the monoball and into a lock nut.

I need more neg chamber in the front. I have KW v3's and RS hubs, tie rods, drop links, sways and Strut brace. I currently can only get -1.7 and want to go -2.5
Does anyone have proven solution for this setup?
Thank you!

An option here is to use the 60 mm spring perch from the front of a street GT3 (or front and rear of a Cup GT3) 996.343.511.90.
As you can see the gold washer, it is another of the washer 964.333.466.83 that normally goes above the monoball that I used along with the normal spacer below the monoball to minimize potential wear issues.

After I posted the above, I realized that it wasn't as simple as my memory recalled. So I am correcting here for posterity in case someone comes along and needs this.
You need two more parts to make it work not listed above, a reducing bush from the rear of a 996 GT3 Cup part number 964.333.466.85 (I know it starts with 964, but it came from 996 Cup parts book) and the gold bush above the perch is the one from the front of the 993 RS 964.343.182.81 which has a 14 mm center bore.
So the parts list relative to the monoball from top to bottom is: 964.333.466.83 (washer) > monoball itself > 993.333.466.80 (adapter piece under monoball for rubber boot) > 964.343.182.81 (washer) > 996.343.511.90 (spring perch) > 964.333.466.85 bushing.
This last part is available from Porsche Motorsport and is a bushing shaped like a tubular "top hat" that will skewer the perch and washer above it and protrude about 1 mm, this can be fixed by grinding off the millimeter or boring a shallow 14 mm recess in the adapter piece under the monoball.

just a word of warning for anyone trying to fit PSS10 with RS top mounts
to render the front spindles long enough to protrude through the bearing left with enough free thread for a tightened nut, you have to do away with the usual RS spacer sleeve and run a duplicate spacer as used on the top side of the bearing. This much we know.
But what I found out the hard way is that under extreme loads and steering inputs the top hat can hit the underise lip of the monoball plate which serves as a groove for the dust gasket to attach to.
My solution was to saw this lip off
I will eventually look into a shallower top hat though as cupcar has suggested and use that spacer sleeve to give even better clearance.

Porsche cut off that ring and dispensed with the dust boot as well for their race parts.
I had to machine a tube nut that plunged into the monoball at the top as well as some other spacers to use the seal, clearance is still marginal though and I think there is some compression of the rubber seal when the strut goes through its range of motion.

^^ lol, we think alike.. here's my solution, these have since been cleaned up & zinc coated. They use the OE 993RS lower spacer along w/ PSS10 top hat & another spacer (not shown).
