Review on Low Profile Plastic Car Service Ramps - Discount Ramps (2 Pack) by Bryan Crayton

Not sure why there are so few reviews on these ramps. Their value compared to more expensive counterparts is great. I've used them a few times to change the brake pads on track days on a low profile M3 competition pack. You raise the front end just enough to gain access to the front center jack point to later jack down to the side jack points. According to the instructions the ramps are wider than my stock tires but that wasn't a problem and I feel safe with that as I wouldn't be working under a car on these ramps anyway. I just make sure they line up with my front wheels well before I drive to them. For ramps that slide on concrete I use a simple fix, propping them up with rubber wedges or placing a rubber yoga mat under each ramp. That creates a lot of friction.
