I have a set of 56" Race Ramps and I'm very happy with them. They're great for oil changes and other under-car maintenance. They worked perfectly for my 2007 WRX (stock ride height) until I installed my STi V-Limited replica front lip. The bottom of the lip just barely catches the ramps before the tires hit, so now I just have to put little pieces of wood in front of both ramps. If I ever end up lowering my car, I have a feeling I'll just have to double up the wood before the ramps. I got lucky and found two perfect-sized pieces of scrap wood at my local Home Depot - they're almost exactly as wide as the ramps, about 4 feet long, about an inch or so tall, and I got them both for $1.00.
