Gary,
I ordered my seat lowering kit from Northwind Engineering. You can find them listed in the vendor area of the forum. They sell a 1" and 2" lowering kit. I am 6"2 and put the 2" lowering kit in my car. With the 2" you can not move your seat back and forwards, with the 1" you can still use the adjustments. It took me about an hour to put it on, feel free to e-mail me if you need any other information.
