It has been said that the biggest improvements that can be made to a Mini is to replace the rubber cone springs. When that statement was made it referred to new rubber cones… there is now a new standard in Mini springing: coil springs! This direct-replacement kit includes everything to replace the harsh riding rubber cones with proper springs. Special hard anodized aluminum perches allow the springs to be fitted to either the stock trumpets or Hi-Los. The highest quality progressive winding is used to insure that the springs will not sag after many years of use, unlike the rubber cones. Available in three spring rates: C-SRP100 is soft (Blue), C-SRP200 is firm (Red), and C-SRP250 competition spec (GREEN).
Oversized rebound buffers for the front are available as part number 2A4267C. Oversized rear bump stop are available as C-SRP015.
Any time you do major suspension work on a Mini involving the front spring (rubber cone), you will need to have this tool (part number 660330). It comes with center posts to work with early (SAE thread 1/2" X 20 fine thread) and late (metric - 14X2) cones. All suspension cones since 1976 have been metric.
