7. The 15 spoke rims are an absolute bear to clean. It takes much longer to get in between all those spokes compared to the seven on the non-SRT model. I would say it takes about 30 minutes just to correctly detail the four rims versus about 10 minutes for the other ones. Which rims look better? It is a toss-up. The SRT rims are actually clear-coated non-painted aluminum, whereas the non-SRT rims are silver-painted and clear-coated. I prefer the SRT's rims more at this point only because they are the lesser seen on Crossfires, but I suspect that I would reverse that thought if the SRT had the seven spoke rims and the non-SRT the 15's.
Here's my advice on cleaning those rims a bit faster and better! I had a set of BBS RX's on my 2000 Contour SVT and what I used to keep them looking showroom new was a lambs wool duster, the one thats supposed to be used for cleaning things around the house. The cleaning portion of the brush is over a foot long, so you can go all the way in the wheel and the handle is long enough so you don't bust your hands up

I picked mine up a local grocery store and I'm sure if you look around, you'll find it or something very close to it. To make things even better, when your all done using it, just rinse it off and let it dry, thats it. A quick twirl makes it big and puffy again, ready to make your life easier. If you find one, pick up two to be on the safe side incase you can't find one again. My previous one lasted quite a long time and for $7.00, its money well spent.
