Not sure where the Boxster spare fits into the picture...

Here's the scoop on the spare solution for the M coupe:

Hunt down a spare tire setup out of a 911 (993 or 996 cars). These are 16" rims with 195/70 x 16 collapsable spare tires mounted on them. The manufacturer of the assembly is Verdestein. The rim is aluminum (steel Porsche spares are 15" and wont fit). New ones can be had from Porsche dealers for around $400, used ones from salvage yards run in the $230 to $250 range. Most have never been inflated, so are pretty safe used parts buys.

Next, you will need an adapter from H&R, part # 50795725-716 which costs $179 for a pair. Sell the extra one to a buddy, or on the message board to someone else putting a spare together. I traded mine for a torque wrench.

Attached is a photo of my setup, including a cover I made from rip-stop nylon that also serves as a tool bag in the center of the inverted rim.
I use the M mobility kit as an airpump to inflate the spare, without tire sealer. you simply use the black air pressure hose connected to the tire, and omit the white sealer hose. The airpump line (black) will fill a tire with air just fine. The white (clear) line is the sealer line, never attach it or use it for anything! Per BMW instructions, connecting the black line back into the pump housing, and connecting the clear line to the tire is how tire snot is forced into the tire.

I love the solution, after a year of hunting, it's nice to have the security blanket.


I saw somewhere, either on this board or another, that you can use the Boxster spare tire with an H&R adapter. It is suppose to fit both the front and rear for the M coupe. I hope this is true - I just picked up a used spare from a junkyard, but I still have to get a spacer.

Just curious...do you guys use a spare? I tried using the Mobility System, and it didn't work for me.
