While I agree about cheap coilovers being bad for a DD car, I don't know where you are coming up with the idea that they can't withstand rain or cold. Not calling you out because I can't prove otherwise, but I also have seen that claim made a few times on this forum with no backing. I bought RCE Tarmac coilovers used with 20k miles on them and they have the slightest bit of surface rust but they handle just great and were previously a DD setup. I plan on having them rebuilt of course when they are due.. but as far as a great DD solution, I love them. The helper springs really allow for a smooth ride as far as bumps and cracks, but they really come alive when I get into some tougher cornering situations. I plan to autocross this summer and we will see then how they really perform. But since you're posting about not taking what people say on this forum for fact, I am wondering if you have any factual info about coilovers not enduring weather because I would be interested to see about that.
