One of the greatest innovations in the design of the Classic Mini was its rubber cone suspension. The compact design and lasting quality of the rubber cone helped make the Mini what it is today: a beloved classic! Designed in the late 1950s, these cones were far ahead of their time. The only problem is that many of us are still driving around on the same cones cones that could have been built in the early '60's; the design is good, but not everlasting! With age, the rubber on these cones degrades, not only getting very hard, but it also sags and loses its ability to hold the car upright. It is not uncommon to have a cone sag so badly that it lowers the car 2-3", causing it to handle terribly! These cones should be replaced every 5-7 years depending on use and climate. Measured at the wheel, the spring rates at the static load position are 118 lb/in at the front and 98 lb/in at the rear. With three passengers and 50 lb of luggage, the loads per wheel at the same position are respectively 468 lb and 355 lb. These loads rise to 1,050 lb and 670 lb at full bump and fall to 240 lb and 100 lb when the rebound check is in operation. Early cones were SAE (UNF 1/2x20), all current cones now have metric threads (14mmX2).

See C-STR687 for stiffer road/rally version ("red dot"), or C-STR688 for race/competition version ("yellow dot").

To completely modernize your suspension from rubber to coil springs, see C-SRP100.

Question:
I have a 1962 Classic Mini. I am riding now on 60 year old suspension cones. What is available as the softest option, coil spring or donut?
Answer:
You definitely don't want the coil springs, they're stiffer still. I would try the standard replacement cones: https://www.minimania.com/part/FAM3968/Classic-Mini-Suspension-Cone-spring-Standard
Be aware that the originals had standard threads in them and all of the new cones have metric threads if you use a spring compressor tool when removing and fitting.

Question:
1975 Mk III/IV 998cc mini question: In September of 2022 I ordered a rear sub-frame MS45D and the mounting kit MS41 and have finally started to remove it. The two rear Aluminum struts need to be transferred the new sub-frame and I will need to install new rubber cones. So, what do you recommend I use, and will order new knuckle joints and cups. Question should I use the original struts or replace them?
Answer:
Sure, you can reuse the rear trumpets (struts) with new cones. Here's the cone part number: https://www.minimania.com/part/FAM3968/Classic-Mini-Suspension-Cone-spring-Standard

Here's the knuckle joint: https://www.minimania.com/part/21A1163/Classic-Mini-Cooper-Joint-knuckle-Assembly-Ball-Joint

Question:
Are these sold in metric, I don't want standard?
Answer:
Sorry for any confusion, these are metric treads.  The word 'standard' simply means stock, not competition.
