I'm in the process of making something myself. Being I have aftermarket side skirts it's a real PITA now.

I could see that being an issue. This 2x4 worked perfect but would of been a major PITA if the car was lowered or had anything that hung over more than the stock side skirts.

I could cut my kit out around the pinch rails. Or I might just go buy a super low profile jack that's about 34'' long and jack it up at the frame rails. That type of jack weighs 91lbs though.
