I've done a few autocross events and recently just did my first PCA DE event. I can't see a future where these things don't exist for me and was thinking about getting some removable numbers for my car.

Vinyl vs. Magnetic?

Any good sources?

 

I use reusable vinyl numbers. They work great.
Here's where I got them.

I use magnetic numbers for autocross, where the speeds are slower. But they don't seem like a good idea for DE/TT use with their much higher speeds. I also use the reusable adhesive vinyl numbers. Mine are from izoomgraphics.com. If you use the adhesive vinyl style, be sure that you clean the door before applying them, and then make sure that the leading edges of the numbers are firmly adhered. Any dirt that gets under the adhesive will quickly destroy their usability.

If the car already has numbers can you use those?

 

I've had no problems with magnetic numbers at the track.

 

If you run with same club all the time then it makes sense, if you run with various clubs then it is unlikely you will have same number assigned each time, so I just print it with 500 font in ms word on a4 paper and tape it inside of rear windows. Works fine and easier than to deal with vinil or magnetic numbers.

 

I'm running with the same club for the most part and they don't allow anything to obstruct the windows.
I figure I can just use painter's tape if I run in a different group.

 

+1 for Solo Performance. I have used both magnetic and reusable vinyl from them at DE's. No problem with magnetic either. Solo Performance is high quality but they take some time. Usually you can request a complete by date and they will honor it.
