Don, I've hand banging on bumps twice, once was a worn mono-ball and once was a loose not at the top.

Don, I am nervous of the restricted movement between the mount and spring perch. It really should have the full range of motion without any contact of the spring perch and mount. This sounds like what had happened to Jackal, though on the front mount.

I have been talking to Rennline about what the proper setup is also because I am just about to so the same mod. It seems to me there is something else not quite right with your setup. This maybe an obvious question, but you do have the 12mm step bushings for the monoballs in the rear, right? The fronts are 14mm.

Yeah, I ageee. Just spoke with rennline, too. I'm going to try it with two spacers on their recommendation.
I assembled it that way but was concerned about it still making contact, but we'll see.

dgmattingley

Yep, 12mm bushings. Maybe the springs need to be lowered on shock?

993KT

I don't have the parts in front of me to do any measurements, but using some basic geometric I came up with about a total of 12 degrees of articulation at the strut mount. That translates to only about 5mm of clearance needed between the hat and bottom of the mount.

Good luck and keep us posted!

dgmattingley

That would be one spacer, right? It makes contact, that I can assure you. Photo shows damage and gap with one spacer.

dgmattingley

Here's assembled with one spacer.

993KT

Oh yeah, that contact alright. The clearance maybe okay between the mount and spring perch, but the bolts are definitely too close. I would think an additional spacer should do the trick.

I see you are using custom springs? Not that it should make a difference.

Need more room than that, here's RS mounts + Rennline PSS10 hats:

Springs are stock, just powdercoated

I used a spark plug socket - one with wrench flats on its barrel, works just like a pass through wrench.

dgmattingley

I did the same. Nuts were tight.

Did you use the Rennline hats front and rear?

dgmattingley

The fronts have the stock pss9 hats.

Something doesn't make sense here, the monoball is supposed to articulate.

If you have removed range of motion at the monoball, then the only thing left for motion is bending of the shock shaft. I think where they say "optional depending on set up" they mean it is either a 12 or 14 mm thick spacer, not elimination of the spacer.
