2nd Gen R56 Cooper S Most liked posts in thread: R56 MCS sport suspension vs standard suspension

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).

Jason, we don't call each other idiots on this site. Goofs maybe, but not idiot

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.

 

I thot there was also a 4th and that's the JCW Sport Suspension (for $1K + installation)

 

the only thing i would really want from the kit is the rear swaybar.

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.

 

	Front	Rear	Strut Type
Standard	22.5mm	17mm	Standard
Sport	23.5mm	18mm	Sport Specific
JSW	24mm	18.55mm	JCW Specific

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.

I see that you can get the red JCW Suspension Spring kit now. Lowers the car by 12mm.

JCE Suspension Spring Kit

ESC Tuning has them for $94 each.

Seams like an interesting mod.
