Who makes these things (Audi AG?) and how are the acquired? I can't believe every tuning house that wants the decals custom fabricates them, that seems awfully silly.<p>Cameron<br>

I inquired about having them made locally at a decaling shop near my house (they do race cars). They said that if i had a picture that they could make and apply them for ~300 bucks. If i had teh exact dimensions i could have them simply printed out for ~100 for both sides. Check around your area and see if there is a shop like this, it would be alot cheaper. Example, for those tiny rings on Ronal's A4 i was qoted 10 dollars for 1 set of them<p>Chris

Having worked copius hours at a sign shop I might have some insight here. The vinyl substrate used<br>in the computer aided cutters comes in 14", 30", and (I think) 58" widths. Since the biggger cutters are big bucks few sign shops buy cutters over 30".<p>I too have been thinking about the TC rings. I plan to scale the 1/10th Tamiya RC car decal sheet. Plot a paper set at work then check them for fit. The plotters are driven just like a regular plotter, so I can bring the file to the sign shop. I would laugh at them if they wanted over 50$ a side to do such a simple job. Application is easy, if you are careful (email me if you want tips). In conclusion, use high quality<br>vinyl like 3M, it will last 10 years if treated well.
