Yeah nick, the spacer I made was 15mm already. But there is an indent where it sits and then the bolt heads on the top hat come down a bit, so I need another 10mm....
And then there is the issue of the upper perch we are using, which is a stock 993 part. The springs sit metal on metal on the perch? But that's not a tight fit. Is this the way Porsche intended for the 993 perch? Or am I missing something? It's the first time I have tried to resolve this issue in this manner, and rennline as usual, has no idea, since they don't do any test fitment....
Here's what PET has for the 993 rear (non RS).
It's hard for me to see from your picture if you have all the pieces located above the spring. In addition, if I look at the Rennline instructions, it looks like you might need the "optional" lower flat bushing.
In the rennline instructions - see the one labeled "shock hat"- that's the 993 part they sold us to go w their monoball top hat. Rather than being conical or a "witches hat", it's flat. So it needs a bigger spacer than the one I made. I'll post pics if I get some while its apart. This would be significantly easier if we were dealing with 2.5 Id springs like on a standard coilover. But since we are mating an oem diameter spring to the monoball, it's just fiddly since no one just makes a kit that works...strange cuz you'd think rennline would just make it simpler...but then not many people make the jump to make this kind of upgrade without doing higher end and more adjustable setups...funny thing is - for road use, this setup is ideal. And a lot less expensive than moving up the ladder ....
Had to re-bleed my car today...there was a ton of air in there...interestingly enough, the one thing I wanted to bleed the most was the clutch, and I completely forgot to bleed the clutch as I rushed through the brakes, pressure booster, PDAS solenoid, and the diff locks...but tomorrow am ill toss the bleeder on the car and whip that out...
So here's the deal. A couple years ago I went to pelican at the behest of my buddies here on rennlist and bought the be all end all of bleeders. The motive power bleeder with the super duper billet alluminum cap and all the goodies. Longer hose etc. but to bleed a c4 fully, I have to refill it a couple times while bleeding. And that's not only a pita, but everytime you glug glug glug a can of fluid into it, you introduce air into the brake fluid. And then you have to either wait for the bubbles to come to the surface of just be super careful adding the fluid.
Solution...go to motives website and buy a 1.5 gallon power bleeder. With a quick release so now I can swap my hose to the little one for c2 bleeding and to the big one for c4 bleeding . Add the right amount of fluid once and done...
On the rear strut issue. I found these in my bag of tricks. Isolators from a 991...these will get rid of the spring noise and then I'll just make a larger spacer and we should be good in the hood...the spacer I made was 15mm. So I'll go 25mm and see how that goes. Should be just what the dr ordered...
Finally on the ground- noise found. The monoball top hats were missing a spacer - the shop screwed up. No biggie...she's on the ground and ready for ride height to be set and alignment. Car 5 getting there...
Off to butzigear for alignment this morning. Of the original group, this is the last car....very exciting stuff. Not done yet, but getting close. This alignment basically closes the suspension project and I move on to some details and finishing - like pop-out rear qtr Windows, etc...
The rennline pedal needed to be adjusted - I had set it like mine. But the pedal in a c2 is harder and higher than a c4...so the pedal needed to come back a bit toward the top and I took out the upper extension as I do with all of them. Now heal and toe is completely natural in this car...
Terrible pictures sorry, but the rear qtr windows were sanded, primed and then shot with semi gloss black to match the oem trim...pics are of the primer stage.
These will get built and installed next week. And then I'll need to drill and mount the correct lower window trim and the pinch welt...and done!
