This is kind of a review on FlatStoppers. For those of you who don't know what they are they are a device you park your car ontop of instead of jacking it up and putting it on blocks which can mess up the additive suspension if your ride has one. I used em for 4 months on my Charger Hellcat. I have to admit they did way better then I thought they would. They are made of a hard plastic/foam type material. Cost around $300-$400 depending on where you buy it. They are a little tricky to drive onto so what I did was jack up each corner and place them under the wheels. Im not really used to doing this so this might be a little crappy and im sorry in advance for that lol.
