-FG is good for racing where the fenders can easily be replaced
This is the time to jump on the group buy since the price is great. I have also seen some great looking cars with FG flares that show checking on the flares. This can disapoint one specially if the paintjob was expensive. I prefer steel ones since glueing on FG ones seems odd to a welder dude like me. I have the FG ones and will probably just rivet them on the outside of the body. I have a FG/CF project and now an all steel version is attractive.

Okay, don't follow me just yet for I am perverted.
