For the over-the-winter garage storage of my 911, the Rail Ramps Flatstopper product has eliminated the need to move the car over the winter in order to avoid the tires developing flat spots.
Order # 26695   I ordered an EGT and a gauge pod.  It showed up at my house 4 days later exactly as I had ordered it.  The Prices are unbeatable!
Ordered a Kirkey seat from them. They had the lowest price I could find and shipped that day. Ordered on Friday and received on Tuesday. It was well packed and perfect. I'd certainly do business with them again.
