Race Ramps (RR-FS-16-SC) Supercar FlatStopper

Very light weight and great quality.

Delivered as promised

Keep kinda steep in price, the payoff will be if they 💯 say what they prevent

These work well for the designed purpose. They are not the easiest to use though. Getting all 4 wheels fully on them at the same time is tricky and takes some time. It may just be me but I have to try a few times to get all four tires on them and so far I have yet to really get it perfect. I always have one tire that is a little too far forward or too far back. But they do keep the tires off the cold concrete and prevent flat spots!

Perfect for long term storage. I put my car up on these if I won't be driving for 30 days or more. If you are deciding between two sizes, get the larger of the two. The supercar one really is for ultra-wide tires... these are great for a 2006 BMW M3.The next size down (14") is good for most vehicles... I have them on a 2007 BMW X5 SUV with fairly large tires.

I have a car in Arizona that I use when we're snowbirding, so from about April to December that car remains stored as we're back up north. Wanting to prevent flat spots I ordered the highly rated Flatstoppers by Race Ramps, fully inflated my tires, and rolled up onto the ramps confident that they would do as they claimed. I followed the fairly simple and intuitive procedures and departed until the next winter.When I returned months later, I uncovered the car, disconnected the trickle charger, and gently rolled the car off the ramps. The tire pressures had dropped from 33 PSI to 26 PSI during storage so I topped them up and went off on a short drive. I immediately felt a wobble!The Race Ramps site suggests that some temporary flattening may occur but that should be able to be driven out after about 25 miles. Well, it DID improve, but even after about 50 miles when driving between 50 and 70 MPH the car felt like it wanted to jump off the road.I should mention as well that these were brand new Michelin Defenders with only a few hundred miles on them. I went to Costco (where I bought them) for an inspection and they rebalanced them but they confirmed that all 4 tires had flat spots. Not a warranty issue.So these brand new tires were trashed thanks to Race Ramps requiring a replacement. Next year I will be putting the car up on jack stands. I have emailed and called Race Ramps and there has been no reply as yet. I will update this review if they accept responsibility.I DO NOT RECOMMEND RACE RAMPS FLAT STOPPERS!

These ramps are worth their weight in gold. Very easy to pull up on and no issues with them sliding or scooting away. They have the curvature to prevent your tires from getting out of round and creating flat spots that ultimately will make the sheets have a thumping sound that may or may not roll out over time.Definitely a must have if you plan to have car parked for a significant amount of time.

Easy to roll your car onto it despite what others say. Only concern is getting the tires to drop exactly to fit the curvature of the ramp. If you are off a couple of degrees I am worried it will damage tires. First winter for me storing 2015 Z06. Will update if it is a negative result.
