I have a 2009 Mini Cooper clubman s, Looking to do an update on all of the suspension components for the best performance.
I'm wondering what parts are the best use to such as; coil-overs, sway bars, end-links, bushings and any other parts that my need updated.
Link any parts that you think will work well.

 

What's your budget? I could suggest a whole slew of parts to throw at the car...

 

No budget yet, but if I have to ill buy parts along the way

 

Suspension is one of those things it really helps to start with a committed plan, so you can gather incrementally, but decide on a direction. Since you mentioned coilovers, a few decision points that might be useful

• Current setup (tires especially)
• Keeping stock ride height?
• Need adjustability?

On my r55 I often carry heavy loads in the back including 3 mountain bikes on a hitch rack and the gear to get us there. So I decided against lowering in the fears it could rub when loaded or be so stiff to prevent that it would be unbearable otherwise.

I went ahead and went with the following:

• poly front control arm bushings (essential)
• stock springs
• Bilstein B6 strut/shock (allows for lowering later if I decided to)
• 27mm Front sway and heavy duty end links (3 adjustable slots)
• 25mm Rear hollow swaybar and end links (3 adjustable slots)

That has stiffened up the car quite a bit, and has pretty predictable neutral to slight understeer. I'm still looking to reduce the understeer without making it too twitchy, but haven't moved beyond this setup yet.

Do you have thoughts on the questions above?

 

Currently running a lowering spring kit with cut fenders and rear seat delete to reduce rubbing with a 225/45R17 tier, I do still rub a little.
I would still like to stay low, but being able to adjustable dose not really matter to me that much.

 

225/45-17 is quite a bit bigger than stock 205/45 tire size. If you’re not running OEM wheels, that could be the cause of your rubbing. I wouldn’t go any bigger than 215/45-17 for your next set of tires.

For suspension upgrades, in my opinion, Ohlens are the best you could get, but they are limited in their lower capability. BC or Megan Racing Euro 2 coilovers will give you a decent compromise between lowering and comfort. I’ve been riding on Megan coilovers for the past 5 years as a daily driver, and have enjoyed the performance improvements.

In the front, you’ll want to upgrade the control arm rear bushing to poly, and add poly bushing to the OEM sway bar.

In the rear, adjustable lower control arms will help get the alignment dialed in from lowering. A bigger rear sway bar will help keep the cornering flatter. Give consideration to poly front trailing arm bushing inserts, too.

The most important item for your suspension upgrade will be a precision alignment. With the coilovers, make sure you’re getting adjustable front camber plates. You’ll want between 1.5°-2° of negative camber per side in the front, and the same in the rear. This adjustment alone will help the car feel more neutral in handling. Add just a touch of toe in on the front and rear to make the car track straight on the highway. Any amount of toe out will make the car very twitchie.
