Six days ago I ordered a set of Race Ramps Flatstoppers, today they arrived and my car now sits atop them. I had my own diy version but these are the real deal. They come in different sizes and I opted for the large (14" wide) to ensure the 335's in the rear would fit nicely, and they do. Car sits for abt 4mos a year so I figured why not. When this Vette eventually goes, something else with large tires that will also sit for 4 mos will surely replace it. The product is very light but appears extremely sturdy! Huh, my side skirts appear to be nicked in the pics but they're not.
