Hi Dan, I think you'll find that drilled rubber cones were a tweak used to soften the spring rate on radically lightened race cars...

Sounds like bodge territory to me. To start, drilling rubber is very difficult. To drill a cone evenly, you'd have to remove it - easier to put a fresh one in at that point. Drilling holes where they shouldn't be would allow the ingress of water and dirt (and the cone would act as bellows to pull stuff in). An already aged rubber might fatigue break or collapse more. I could see it done on a fresh cone to get specific handling, though Moulton had the original cone design dialed in for the original Mini. When he designed the Smooth-a-Ride cone, he changed the inner and outer profiles as well as the height. It came as a set, with adjustable trumpets and selected shocks to suit the different spring characteristics.
When I installed mine, the adjustable trumpets were wound just about all the way in until the new, taller cones settled in, which from what I read at the time might take a few weeks. My mini is not a full time daily driver, so after several years it came down to close to proper ride height. I still have not had to re-adjust them. One benefit of having adjustable trumpets is you can balance the weight distribution.

Dan, people use to drill holes in the rubber part of the cone to try to make them more compliant.
Does anyone know how long a new cones lasts these days. I've been running LSS springs from Japan as my mini is my only car and a daily driver. I can't take the jitteriness.

My guess is that you need new cones rather than shocks. The cones are hard as rocks and sagged.

Recommendations for 1993 Mini BOC shocks? Currently running originals that feel beyond expired.
