    :mad2: Mini Margi is an 08 MCS JCW(Dealer kit) R56 that has a sport suspension (not sport package but sport suspension) listed as such on the window sticker with all the other options. Trying to find out which componants are different and how they are different(specifications of both) has been like trying to find out your girl friends age and weight. Mini USA states that the springs are heavier(no mention of ft/lbs thankyou very much)and they lower the car by 8mm over stock. They state that the shocks(dampers) are heavier also. What the heck does that mean? There's no mention of the difference in compression damping or rebound between stock and sport suspension. There's also no mention of antisway bars. I've measured the rear bar's circumference and dividing by 3.14 get 22.something;so it appears that the rear antisway bar is heavier. Does anyone (Dr Richter,Nathan,TSW,others)know which componants are different and what the specs are on standard and sport parts? The car handles better than I can drive her but I'd like to know the differences.:confused5: Thankyou Jason

    I have the same on my '08 MCS. I can't speak to the specifics, except to say that the rear antisway bars are 18.5mm which is the same model as on the JCW

    Check out realOEM.com. The standard antisway bars listed there are 22 mm front and 17 rear. The JCW bars are listed as 24 front and 18.5 rear. Unfortunately the spring specs are not shown.

    The springs are sized based on the options that came with your MINI (weight).

    Standard vs Sport Suspension

    :D Thanky'all very much. Every little bit helps and now I know that I just may have erred in measuring the rear sway bar. This is a very friendly and helpful site. I've got several posts and haven't been told that I'm an idiot yet.(okay I've set y'all up. You can call me an idiot now.:lol:) Jason

    Where did you see that? Sport suspension is the same height as standard suspension. The JCW suspension (dealer installed, purchased separately) is about 1/4" lower.

    Sport suspension has different springs, shocks, and both sway bars. JCW suspension includes yet another different set of all those components.

    BTW, just making sure there isn't confusion about it... the dealer JCW (engine) kit doesn't include JCW suspension.

    No, that's not correct. There are 3 suspensions offered by MINI:

    1. Factory standard suspension
    2. Factory sport suspension (struts, springs, sway bars stiffer then standard)
    3. Dealer installed JCW suspension (struts, springs, sway bars even stiffer than factory sport suspension)

    Okay this has me interested. I picked the Sport Suspension option with mine and I am curious to know the actual ratings on the suspsension.

    When I test drove one with and one without I could feel the difference in stiffness and it seemed like the sport had better turn-in though I am far from an expert there.

    just my opinion. :)

    There is only one JCW suspension. Sometimes "Sport" is used in the name, sometimes not, but it refers to the same thing.

    But I believe there's the stock JCW suspension and then there's the upgraded Sport suspension for about $1K (excluding installation) (Morristown MINI)

    According to RealOEM, here's the parts for the JWC suspension http://www.realoem.com/bmw/partgrp.do?model=MF93&mospid=50964&hg=31&fg=10 and then here's the parts for the JCW Sport suspension http://www.realoem.com/bmw/showparts.do?model=MF93&mospid=50964&btnr=31_0806&hg=31&fg=95. The struts are listed as seperate parts

    The dealer-installed item called "JCW Sport suspension" on the RealOEM and Morristown MINI sites is the only "JCW" suspension available.

    A factory JCW S is fitted with the exactly same suspension as a regular S (either standard or sports suspension).You're just misunderstanding the title at the top of the RealOEM page. It says "R56 Coop.S JCW" because that's the model you selected. It will say that on the top of every page. Compare the actual part numbers between a
    regular R56 S: RealOEM.com BMW R56 Cooper S Stabilizer, front
    R56 JCW S: RealOEM.com BMW R56 Coop.S JCW Stabilizer, front

    Another newb question: I'm seeing strut info and sway-bar info. Does that mean the spring rates are the same?

    Part 2 of the Newb question: Are the sport springs a progressive rate or linear?

    *zips up newbie flame suit*

    Whether the sprigns are progressive or linear is a moot point, since you will be using the progressive foam bumpstops as part of your spring rate essentially 100% of the time.
