Great question, I only took one picture of my work and this one does show it fairly well. The grease is coming out between the boot and the flange. The clamp was loose and i could rotate the boot around back and fourth.

You can also see some of the grease splatter. The cup still had lots of grease in there when I took the axle out so i have no worry of wear but the R32 took 15 years before it started to sling.

There have been other reports of those Oetiker clamps being loose/big from the factory. I'd probably replace them with work clamps of the same width and make sure they are tight. You can try squeezing harder on the crimp with Oetiker pliers, but if they are already loose, I doubt you'll be able to cinch them up enough to really help. Dealer would likely replace the boot and clamps and bolts under warranty, but that might only buy you another 2 or 3 years if they haven't fixed the issue yet (which they may have, I don't know).

@Tom thanks for the tips, that is quite helpful. If my "fix" does not do it I will try worm clamps, may just buy some in the appropriate size just to have them on the ready.

150 miles today, mostly on Cascade foothill backroads, with ~25 miles of freeway on the way home. And the initial impression is good. Nice steering response and feel, good ride quality, and while they are still new and at their best for noise, they seem to be very quiet. The tread design looks almost the same as the previous version Michelin PS A/S 3+ with wide grooves, big blocks and limited siping. So like the Michelins I don't expect them to be useful in snow or ice, and as an all season tire I don't expect they'd hold up well for track use. But I rarely get snow and ice around here, and when it does happen it only lasts a day or two, so I can leave the Cayman in the garage for that weather.

As a side benefit here in the US, they are quite affordable. Discount Tire sells the set of 20" for Base, S and GTS for $804 shipped, or just over $900 installed (plus tax for those not here in Oregon).

All in all, I think they will do me just fine.

Those look fantastic! I've been considering going with a set painted racing yellow to match all our other yellow interior bits...still on the fence regarding whether it would be too much yellow.

Yeah, it’s definitely a “look” to have paddles in a bright color. I have some elements in my interior that’s bright—door handles, seatbelts, and fire extinguisher. I found the bright painted trim can get to be a bit too much when sprinkled all over the place.

So for my car, I went with black paddles:

So with no pictures I wanted to give an update on the leaky CV boot that I reported earlier. The fix was a smear of RTV and new clamp, add grease, it worked.

What did not work.....
The 6 CV bolts came loose on me a week later and the axle flung around and broke my hydraulic clutch line. Since I was the one who tightened those bolts I take full responsibility.

The Repair...
The aluminum clutch hard line is two pieces between the clutch master cylinder and the rear of the car. At the rear of the car there is a short line that contains a segment of hard and soft line. In my situation this short line was bent/broken at the connector to the rear hard line. The last 6 inches of the rear hard line was also broken. The rear section of the hard line is not available anywhere but Germany and it will take weeks to get here.

What I learned is that Porsche and many others use a quick disconnect in their clutch lines. I went to a local hose and and fitting store in town and had a braided line made up with this same standard clutch quick disconnect fitting on the slave cylinder side and a flare fitting on the other side. I had pre-measured and had this line made 5 ft long. Installed the line and chose a convenient place to cut the aluminum hard line and used a flaring tool to create a nice double flare. 5 ft was way longer than I needed but brought the flare connection to a spot that is easy to get to, make the flare and inspect for leaks. Reconnected and routed the new braided line in the same clips that the original clutch line used. To my eye, it looks very professional.

Had a bit of a hard time getting the clutch line bleed until I used the reverse bleed method, that worked a treat and the clutch pedal was back to normal. One thing that was not normal was the sound of the clutch slave cylinder, it was making noise, sort of a creaking sound. After 20 or so cycles of the clutch it also started leaking. I had removed the slave cylinder to better understand the system as well as the clutch quick connect fitting. It is made of plastic and does have white marks where the plastic was stressed from the clutch line getting yanked. It is also possible I did not install the slave cylinder properly but there is one hole and a bolt. I will be more careful when the replacement shows up on Monday.

The CV came loose on Saturday night after a great track day where I absolutely had a blast. I had already pair for both Saturday and Sunday at the track so Saturday night after the tow truck dropped me and the car at home I put my track wheels and tires on the R32 and gave it a quick wash. It did great on Sunday at the track, not as fast as the Cayman but still fun and I got track time.

So I had some success and some failures and many opportunities for experiences and fun. I will take it! Will update next week when it is back together and I have another update.

So sorry about all that. :( Porsche hive-mind says to use new bolts, clean everything completely, and torque them to spec in a star pattern, in stages. If that doesn't work, then you can always safety-wire them, or use the Stage 8 locking bolts. Not sure if Stage 8 has a bolt that matches the 718 CV, but I'm guessing they'd make it if folks asked. They made a set for the 944 with fairly little encouragement...

What happened is interesting - maybe I should say that it raises the eyebrows a bit. Makes me wonder since I've had them loosen too. But like Tom said - all new bolts, among other parts and methods. (My repairs on passenger side CV was done by our A+ dealer and my A+ Porsche tech.)

However Jeremy, your skills coupled with your ingenuity and ability to diagnose and correct on your own is impressive. :thumbup: Will be educational for me and others to see how it all turns out.

Very good that you were able to get your backup track car out and on track for your paid-for 2nd day. No waste!
