The tire size is 185/60-17

 

Looks like a nice kit - but really wonder if it would work with PCCB's...

 

Wow - thanks. There is a Porsche "tool" kit that goes with all this stuff. It has a lug wrench and various other tools including the alignment rods that assist in mounting the wheels. It is expensive though. I found one of these kits and a jack on e-bay. I just need to fill in the other bits and I'm set. And then figure out how to mount it.

Keep us posted on your mounting idea.

 

Will this work with a C4S?
- brake clearance
- available space in the frunk?

Thanks

Edit: Nevermind - I see now that the OP has a C4S

 

Yes, my car is a C4S

 

Not sure if we're beating a dead horse, but looks like a spare tire is an easy upgrade for a Cayman. Just tested it, and it seems to be made to fit, and straps down with existing hardware. Has anyone done this before? Not sure if we found something cool, or if someone else has already tried it.

 

On my C4 with the CD changer in the trunk, I secure the collapsible spare ( $150 on ebay) there with 2 nylon straps. One to the clip on the back of the trunk wall (not so strong), & the other to the strut below the floor panel of the trunk where the compressor used to be (quite strong). No movement @ all. I also carry a plug kit. Sort of a belt & suspenders approach.

 

The spare tire issue is not a dead horse. I have a 997, NOT an S, but with factory 19" wheels and PASM, but NOT with the larger rotors I examined both the 996 spare and the Cayman/Boxster spare tire (the socalled bicycle tire- 105/95 R17) It is thin and tall, and comes fully inflated. It seems to me to be more substantial than the 996 spare, which is collapsable, but none-the-less does not fit at the bottom of the frunk as it does in the 996 because they redesigned the space on the 997). The part number, inexplicably (because I was told it was Cayman/Boxster spare and it looks like the one I examined) is 996-362-130-01. I have tried the spare on both the front and rear and it works in both places with enough rotor clearance. My question for the person who sent the earlier email (suncoast?) it you said "straps down with existing hardware." How did you strap it down? in my front, it will fit standing toward the back of the front (too tall unless I deflate it) and do not see places to strap it to. I currently have a long thin piece of plywood the wedge against the tire (which is sloped in the frunk area) and the sides of the frunk. Not too high tech, but it seems to work. I would just like to secure it better, and perhaps get it to stand so I get more frunk area. Thanks for any replies. -M

 

This particular spare tire cover has nylon straps and metal hooks. The Cayman has the appropriate hooks for attachment, and it made this an easy installation for this car. For Carrera and Boxster models, custom fitment seems to be required.

This tire is not inflated, it's the collapsible type.

 

add me to the group buy

 

So it sounds like we still don't have a USA solution that will get us the parts that a Guatemalan C4 would have in the frunk. Why the heck is this so difficult for a dealer to get set up? Is Porsche AG purposely blocking the US market from having access to the parts? Come on Porsche! Sheesh.

 

Here is an approach I used to temporarily mount the tire, while I search for a better method. When you remove the air compressor housing on my 997.2 C2, you expose the mount for the dynamic cornering lights controller which is welded to a bar that runs horizontally across the back of the "frunk". There are two, fairly sturdy tabs on this mount that have two holes each that will clear an M8 bolt. Using some 1" wide nylon lashing strap and a tarp eyelet kit, I created two custom straps that could be mounted to these tabs. The other end of each strap has another eyelet for connecting to the tire cover clips. That covers the top two clips.

For the bottom two clips, I removed the black "cones" that locate the base of the compressor housing mount and attached two more lashing straps to the exposed posts with a thin walled nut. This allowed me to replace the cones with the straps attached. The bolts in this location are fairly small in diameter, so I don't expect them to take a lot of force without bending. Hence the temporary nature of this solution.

Replacing the compressor cover now leaves the ends of the securing straps exposed. I deliberately made the bottom straps longer than necessary at this stage since I wanted to use the tub liner I bought for the car for added support. Final photo shows the tire secured with the straps on the tire cover attached to the custom straps. The fit is very snug, but not solidly tight.

Using the tub liner raises the tire height to the point where you would worry about the hood coming in contact with the tire. Fortunately, the highest part of the tire slips into the space above the location where the cross welded hood struts come together. The hood closes without contacting the tire. However, I do recommend a Das Schild hood protector if you decide to try this.

Has anyone come up with a better way for the 997.2?

 

Nice pics - thanks.

 

Nice pics, looks real neat. How bout if one had the inflated donut, the Cayman/Boxster spare tire/bicycle tire- 105/95 R17. Any idea how to have this secured neatly, or should I try and get the collapsible spare most are using???
Do any users have preferences to which is the best spare option for a 997???
The collapsible or the pre-inflated???

 

I a 997 and bought the "bicycle tire" type spare, which comes fully inflated. I have it sitting upright in my frunk on the deep end. I thought I would need to somewhat deflate (which was OK since I have the OEM compressor, but found I could close the frunk lid with out forcing it. This approach gives me maximum space for other things I carry I believe the way the lid it design, it holds the tire firmly. If any of you out there have an experience to the contrary, please let me know. Thanks, -M
