Replacing rubber cones with steel coils - Boyscout - 08-04-2020
For all those that wondered if the steel coil spring conversion is worth it, it is not. I had the steel springs in our Mini. At first the ride seems great but the suspension does not have enough travel to give any benefit. As you know steel springs have a linear compression rate whereas the rubber cones have a compound rate. So if on a perfectly smooth road the steel is nice, a very supple smooth ride, but it would hit the bump stops on even the smallest undulation. This was with the ride height set to standard. By the time you have springs stiff enough so it would not hit the bump-stops, it would be a very uncomfortable ride. So I replaced the steel springs with brand new rubber cones and wow, what a difference. It handles speed bumps with ease and the comfort is as good as you can get with a mini. So to those that consider this mod, don't do it!
