When does SFI cert. run out?

[Freddie]

I agree, I had a flex plate re-certified over the winter, was told to ship it back because they had to inspect and re-weld the plate. When I got it back it was the same plate I sent them, not touched except for a new SFI sticker, they didnt even re-paint the thing for $50. After shipping both ways my re-cert on the flex plate cost me $68. Worst part of it all was that the plate had only been used three races(took me that long to get the car done). Still a crock considering if thats all they were going to do they could have just mailed me the stupid sticker and saved me $$$. But I guess its still better than having to buy a new one at over $200.

I dont understand why some of these certs are so short, other than a deal cut with NHRA to keep us sportsman racers broke.
