I bought a new aftermarket Cayman wheel on eBay which looks great by the way and free shipping. I had a new tire mounted on it and put it in my trunk to replace the original temporary steel wheel and Pirelli tyre from 2004. Notice the Pirelli has the word tyre instead of tire on it so I know it’s original. Fits great in the well but the threaded bolt that held the original spare down to the jack mounting bracket is not long enough with the larger full sized wheel depth. Have you guys that have gone to a full size found a solution for this short bolt? Thanks

 

Well I just found another thread and a link to Terry’s Jag where they had the bolt for 17 inch wheel and ordered it. Here’s the link

I walked around the junkyard looking in trunks until I found something long enough. Can't remember what it came from. It's a fairly standard thread.
