Like many, my "R" decals on the brake calipers were almost invisible. After scouring this board I couldn't find a reasonably priced solution. Didn't make sense to put the same OEM decal on to just wait for it to fade. I like the "R" and found these little jewels:

High Quality R Performance Key Chain

They are almost the exact scale of the caliper decal. Coincidence? With a little work with a dremel I cut off the chain loop. Tin snips to cut the loop and a file work just as well. I carefully cleaned the caliper to remove any oils. I used 3M double sided gel-like super mounting tape. I was waiting to post until I proved durability. They have been on over a month and survived many washes and heat cycles.

They are chromed brass so they won't rust. Gives it a nice 3 dimensional look too. I use heavily diluted Simple Green to clean the wheels.

New set is only $48 for all four!!!

 

Nice! I was considering the very same but, I thought of using a two-part epoxy glue instead of the double sided tape. There is a lot of heat and vibration at that location and I was concerned that if the relatively heavy piece came off the speed, it could damage the wheel. The part that it is glued onto is a simple, cheap, easy to remove plate that could be replaced if and when needed.

 

Fly2c2, looks good I was considering the same, concerned about them flying off after awhile. Reason for my post is for those of you considering the "R" check out bay's link............3D XF R Logo Metal for Jaguar XF XFR XK XKR Supercharged Emblem Badge Sticker | eBay

 

Way too big...that's the same size as the rear hatch badge.

The original caliper decal is closer to 1 inch by 2 inches which is the exact size of the key chain fob.

The 3M tape I used is good to 300F so it shouldn't come off. I'll post if it fails.

 

I bought new decals from the eBay seller below. He was SUPER nice and it didn't take that long to get over the pond

SUPERGRAPHICSF1 Brake Decal Sticker Fit Jaguar R Front R with Red Green X1 | eBay

He offers both the Lime Green stripe for newer models and the Dark Green stripe for older models.

I have had them on for over 3 months and live in Texas with stop and go traffic, along with regular car washes and they haven't given out in the least.

 

I like those decals listed on EBay. It said that you must paint the calipers first. Not sure what that means. Did you paint yours first?

 

Ive just painted my callipers red and orderd the 4 key chain emblems , I like the 3 D affect,will post pics when completed. Bernie
