Tom - just curious - at that angle - how much clearance is there to the inside of the frunk lid? On mine, I tip the bottom of the tire toward the front of the car to lower the height to about what the compartment cover behind it is. I haven't tried any crushable foam to see how much clearance there really is - but it seems awfully close to me.

Not sure I posted this pic here- but this seems preferable to epoxy and you can put a false floor on it.

Pulled this from another rennlister's post. If I cut a cardboard template with a hole in the amp is, and cover it with mouse hair felt, I can then mount the tire up against the piece of cardboard (which I could then replace with the factory piece if modified), which would give me just enough clearance (take the air out of the tire so no pressure on the hood) and maximize frunk space. Of course the simplest thing would be to tilt the tire like Don does. But then what useless challenge will I have.
Don, Wailn,
The hood closes with the regular spare upright. But i feel resistance which means there is some pressure. If i get rid of the board, like what Wailn did and stand it upright, there is about 1/16 of an inch between the top of the tire, and the top of the hood. If the picture uploads, that is from me taking a piece of string across the hood, then opening the hood. Not the most precise.
That's why i was thinking of the collapsible spare Wailn has. But those go for a lot more $$ and i already have the other spare. I like what Wailn did, but the tech inspectors may give me a hassle if i move the amp. The car has a strong track history, and the PO built the motor for enduros. But it is also in concourse condition, with crimson calipers.

The board is held in place by two nubs on the floor. The tire fits in there perfectly keeping it from rocking left to right. I may cut a piece of cardboard to match the board without the step it has. if that allows me to put the tire the inch or so farther back, i may Velcro the pump and tool kit to the storage area where the CD changer would go - assuming they would fit. Then if a that works, i can take the board that i got off eBay and cut the step out.

Wailn, you and I are on the same page regarding the plate. I bought a 3.5" square plate with a 1/2" slot for about $2.25 at lowes.
I typed the response on the computer, and added the pictures from the phone. What a PITA.
Top picture is what i think is the clearance without the board/panel.
Second picture is test fit with the panel. Everything looks great, but there is slight resistance when i close the hood.
Third is what it looks like without the spare. You can see where i cut the eBay panel/board. I can pull the bolt out when on the track, and the only thing showing will be the small piece of the hinge base which will be firmly attached to the car, so OK for the track.
To do: see how far the amp sticks out, and how hard it would be to cut the plastic panel where it is, leaving the carpet intact, and making the panel flush, and seeing if the pump and tool kit will fit in the spot where the cd changer goes. That would be my easiest, and give me the most room in the frunk, which for the track is not as essential as it was two weeks ago. I bought the 4' tire trailer from the PO since it wont work with his GT4.

I posted a how to of what I ended up doing. Here is the link. Mounting A Spare In A 987.1 Frunk - How To - Rennlist - Porsche Discussion Forums

i have searched this thread and still don’t really have answer. I know the 986 ( 17 inch rim) will fit in my 987( 18 inch rim ).
the question is am I going to damage the car running a slightly smaller diameter on the rear or front. Even if I move the front to the back ( stock front tire is smaller in diameter than the stock back )

millions and millions of cars were sold back in the 80-90's that had OEM "compact" spare tires with a much smaller diameter rims. i once rented a car at the denver, co airport, had a flat within five miles and was forced to mount (on the berm of interstate 70 in golden, co) the "compact" spare tire. it looks ridiculous BTW when mounted. anyway... i continued on to steamboat springs resort with a entire car full of anxious vacationers, in miserable weather, without issue. IMO, it's a legitimate solution. the main issue is ensuring clearance for trunk, fender and brakes is sufficient maintained, both when stored and mounted.

i wouldn't be surprised if "self-inflating" ones were offered to save even more space. dumping one in the front trunk, wouldn't be much of a problem, space-wise, i wouldn't think. ...don't forget the bolt hole pattern must match too.

probably should fit a proper wheel and tire for track-days though.

Yes. The 986 “donut” spare fits the 987. The purpose of the “donut” spare is to get you to the nearest tire shop. So long as you use it for that, it is fine.
