R56 Suspension: Cooper vs Cooper S

Suspension: Cooper vs Cooper S
Ok...I dropped Winston (Cooper S) off at Concord Mini and they gave me a regular Cooper. Key chain says 2003, but I suspect 2007/08. (Past two times I got a Z4 and a 1 Series Convertible...so I was a little disapointed.
I figured it wouldn't drive as well, and would be disappointed with it. Low and behold, I was pleasantly surprised. The ride was smoother, and didn't seem to get bothered by the bumps as much as my car. My car would be bumped off line when I do fast lane changes, and I could feel the understeer in the turns. Not so with the Cooper I drove it pretty hard, but I have to say a much smoother ride overall.
Winston is an S with non-sport suspension, but with upgraded 17 inch run flat performance tires. As far as I can tell on the loaner it has regular 16 inch run flat tires made by Goodyear.
Anyone care to explain? Cause the loaner felt way more like a go-kart, and seemed to not push as much through the turns.

I currently own a PS/B 2008 MC.
16 inch tires on the Cooper absorb more impact. More rubber, less rim.
The suspension on the Cooper S is stiffer. I am not sure how much stiffer, but my guess would be 10 - 20% depending on whether it is the stock MCS suspension or the sport package suspension (even stiffer!)
Not pushing through the turns? -- that has to be a hp/torque related thing. I love my MC. I do a lot of highway driving now for work though, and it doesn't inspire confidence with the faster moving vehicles.
Still-- a great car.

I thought both suspensions were the same base Cooper vs. Cooper s. I have the stock Cooper S suspension.
I suspect the tires are a big factor as well. I must say the regular stock suspension on the Cooper is a better daily driver type suspension. But the power is consdierably down on the regular Cooper. I had to downshift to 3rd to get any type of passing power.
Anyone know for sure if the base cooper and base coopper s have different suspensions?

The MC standard tire size is a 15" non runflat. If you order 16" tires with your mini, from the factory you'll get runflats.
Most people with MCS who switch out the tires to a non-runflat version for 16" or 17" report a better ride.
I personally love my 15" continental all season tires. They are great and the car handles great.

I have never seen a MC in Canada with NON runflat tires. I think there is a base model called the MC Classic which has regular tires. The car is only available in 3 colours though.

The ride quality on non-sport 16" RF MCS is much better than 17" RF. Before I test drove both version I was sold on 17" look, but 17" is really bouncy/hard on anything less than smooth surface, and the chassis feels less stable and less composed despite having "grippy" performance tires.
For me, 16" RF MCS's ride quality is similar to a GTI with 18" Monza wheel non-RF.

I say the difference you notice in the ride/handling is due to the different tires, not the swaybars or springs. I wore out my 17" Dunlap Sport RF tires and went with Bridgestone non-RFs and the ride difference is dramatic, especially the "bump steer" factor that you desribed in your first post.

I WONDER HOW OUR CARS WOULD RUN WITH NON-RF 16'S? I BELIEVE AUTOX'ERS RUN'EM THAT WAY.

We've got an MC and an MCS, they both have sport suspension and 16" wheels with real tires (not run flats). The suspensions are pretty equivalent, the MCS is corners slightly faster if you really push it. I didn't get the 17" wheels as they seem to ride quite harshly when I've ridden on them.
The biggest difference you can make to the ride and to the handling is the individual tire model you have. Runflats tend to have a harsher ride, but the latest set I got with Shawn seemed to ride quite well (for the 10 miles to the tire shop). The ride difference between the Goodyear GS-D3s and the Yoko S.drives I have on the two currently is quite pronounced. The S.drives are much smoother.
The tires could well explain the differences, some tires just suck. I'd also wonder if the MC had the sport suspension from your description.

I have a MINI Cooper Classic and it comes with the 15" wheels and no run flats. Thank god! The ride is nice and I wouldn't go to anything bigger than a 16" lightweight wheel. It makes a big difference in acceleration between tire sizes and weights. A 17" wheel does look the biz though.
Keep it light with Coopers!

Well, if you have a non-sport suspension and the loaner did, it wouldn't surprise me that you had less understeer. The MC with sport suspension and non-runflat tires would be a cornering and comfort king over a MCS with standard suspension and runflats.
Easier to corner is due to less power. I remember my 1992 Protege with tires meant for significantly more powerful vehicles and I could floor it through any corner! 90whp just doesn't stress your tires that much... but it sure was fun! But option for option, the MC and MCS should handle almost the same.

In Canada (and the USA?) if a car is not sold with a spare tire it is the law that the car must be sold with runflat tires.
I have never seen a MC in Canada with NON runflat tires. I think there is a base model called the MC Classic which has regular tires. The car is only available in 3 colours though.

With regard to MINI's, mine has a spare AND came with runflats

Guys,
I just took delivery of my 2009 MCS last night. I love the car but the factory sport suspension on 17" wheels is just way too harsh for me . Question to all 2009 Cooper S owners with SS, what did you do to improve the ride of your car? I'm thinking about ditching the Runflats and just get a set of all season tires, is this a good idea? I would surely appreciate your suggestions.. -Thanks

The '09 Honda Fit, when equipped with an automatic, has non-RF tires but no spare. It comes with a tire inflation "kit" instead (sealant, pump). At least I know it does in Canada.

For the best ride so far a set of Yokohama S.drives or Michelin PE2s are pretty good.
