Well...... here's the thing, they only sell in bulk, so get with your local MINI club and find 12 other people that want them also. I paid $12.52 + shipping for a bag of 25 caps. You need at least 1/2" under the top surface to leave room below the cap for it to lock under the rim of the strut tower top. There are little spring tabs. The ones I ordered are P/N 85985K35. Look on the same page for a different cap that appears to be a lower profile P/N 9750K35. The temperature rating is less so make your own decision. I suppose you could trim down the nylon one's I got if there is interference with your Vorschlag plates. The R56 has a 2-1/2" hole. http://www.mcmaster.com/#85985k35/=9qfor9
Hey, that's a great idea... Maybe for the MOM Christmas party/breakfast/gift exchange/Wednesday dinner get together ????
Mmmmmmm.............. Oh I don't know, might be a good possibility.:ihih: To make them go farther, maybe one per MINI........ what do you think?:devil:
