If you're looking to give your Mini Cooper a serious upgrade, the ACT Heavy Duty/Modified Street Kit (BM2-HDMM) is worth checking out. This kit features ACT's most popular heavy-duty pressure plate, which is designed to handle the demands of spirited driving while still being suitable for everyday use. The diaphragm design on the pressure plate is pretty clever?it increases clamp load, cuts down on deflection, and helps your clutch last longer. Plus, every diaphragm goes through a four-stage heat-treating process, which really boosts performance when you?re pushing your car to its limits.
The modified spring-centered street discs are another highlight. They come with a premium organic friction material that has a high copper content, meaning better heat transfer and durability. The steel-backed lining adds to the burst strength, so you know it can handle some serious wear and tear. These discs are engineered with reduced marcel, which means you get faster shift action?perfect for when you want to drop gears quickly. And don?t worry about engagement; it?s smooth and quiet, which is a nice touch for daily driving.
One of the standout features is the heavy-duty torsional dampening springs. They?re stronger than your standard springs, and they?re designed to match the best sizes and rates for your application. This means you get a clutch that not only performs well but also feels good under your foot. It strikes a balance between light to moderate pedal effort and smooth positive engagement, with just enough feedback to keep you connected to the road.
Now, if you?re thinking about installation, you can find detailed instructions here. It?s not too complicated, but it?s always good to have a guide handy.
