Thanks Matthew, My gli is a street car, but I don't really drive it a great deal anymore. I have managed to rack up 4000 miles since finishing the engine rebuild last September :)
Wow, I checked out the price of the dtc-30 pads and they are just over $100 for the front. Last set of mintex redbox pads I bought cost me $70 for all 4 wheels. I'll give the dtc-30 a try at the next event though.
