Here are a few key things about the ST Coilovers:

Made by KW Suspensions, the leader worldwide for height adjustable coilover system. ST Suspensions belongs to the KW Automotive company which also owns KW Suspensions, Belltech Sport Trucks and LSD Doors.
Adjustable Lowering Heights Front: 0.8"-2.0" Rear: 0.8"-2.0"
ST Suspensions - Spring Strut Construction
*Excellent all around performance, providing a balance between performance and comfort for everyday use
*High-quality components for long durability
*Use of twin-tube technology, independent reactions from damping inputs minimized chassis vibrations and increase driving dynamics
*Coilovers come with all necessary components, vehicle-specific certificate and installation instructions
Functional principle of twin tube shock absorbers:
With a Twin-Tube shock absorber, the piston works inside of an inner Tube. The space between the inner tube and the casing is used as an equalization chamber. Changes in volume due position of the piston rod change the oil level in the equalization chamber between the outer casing and inner Tube.

Compression phase:
When the car swings downwards in the direction to the road, the piston rod is moved downwards.
The oil displaced by the piston rod is pressed into the equalization chamber between the Tubes via specially designed orifices in the compression valve at the lower end of the inner Tube. The resistance that is created through this valve creates the actual compression forces. Oil underneath the piston
also flows upwards through the piston check valve with low resistance which also influences the damper characteristics.

Rebound phase:
When the car swings upwards, away from the road, the shock absorber is extended. The piston rod
is extending outward from the housing. The rebound phase valve at the lower Tube resists the oil that flows downwards through the holes in the space above the Tube. Therefore the upward motion is slowed down. When the piston rod is pulled out of the case, its volume is balanced out by the oil that flows from the equalization chamber back into the inner tube through the compression check valve.

 

I'm really confused. I'd love to get a set of these. So on the ST website, it shows that the lowering range is 1.2 - 2.2". But, if you download the application guide from the ST site, it shows 20 - 50MM lowering range. 20mm equates to ~.8" - 2".

Your site shows 1.2" - 2.2" but in this posting you show .8" - 2". Which is it? LOL. I'm asking because for daily driving I'm going to ride at almost full ride height. I may lower it more for some track days, but for the most part, I want to ride with it nearly full height.

One other question that I have is will I need to run spacers? I'm going to run factory wheels. Other owners that are running the KW V1 report that spacers are required.

 

02-06 Mini R50 is .08" to 2.0" front and rear. All other Minis are 1.2" to 2.2". In combination with the original wheel and tires, wheel spacers might need to be used.

 

awesome thanks. I'm going to place my order now :D

 

Just placed my order...I can't wait..I don't even have a car to install them on yet..LOL!!!!

 

LOL. I am processing your order right now. If you have any questions in the meantime let me know!

 

I just purchased a set of these for my '11 MCS also. Do I or don't I need spacers with the factory 17" wheels?

 

If you are running factory wheels and tire size it is possible. It seems to be hit and miss in most cases.

 

Any questions just let us know! Thanks to all those who have purchased from us.

 

Check with me after tomorrow and I'll let you know. I'm installing mine tomorrow. I have both 5 and 12 mm spacers so I'll tell you what I need.

The size of the spacer will also be determined by how much you plan on lowering the car. The lower you go, the lower the adjustment collar will go. The adjustment collar is what may rub on the wheel/tire.

 

Just thought I'd respond back to this post. I did a little write up on my setup here: https://www.northamericanmotoring.co...-pictures.html

To net it out, I LOVE these coilovers. And the service from The Suspension Source was FANTASTIC!

Bao...I'd love to use this on our website. Please send me this file sales@thesuspensionsource.com

 

Does the r50 application work on all other 1st gen models as well?

 

02-06 R50 part number for ST 90242

 

What I asked is if the r50 part number works on other 1st gen MINI's, i.e.: r52 (supercharged S convertible) and r53 (supercharged S coupe). I believe the r52/53's had slightly different brake/wheel setups than the r50, but I'm not certain of that.

Ah, perfect, thanks!

 

No problem. Let me know if you have any other questions.

 

is there any special pricing for the st coilovers if i get them thru nam?
or any sales coming up?

 

Shoot me a message or call me. I will get you a good price

 

Ordered mine today! Can't wait!

 

AWESOME! You're going to love them. I LOVE them on my MINI. The ride is soooo smooth and it looks great too!

 

I enjoyed your write-up on them, very informative and I love the stance of your ride now. I'll be going with 5mm spacers as well. I can't seem to find out if I'll need them all around or just for the fronts. Any idea?

In any case, I'm pretty excited. My car will be "finished" () after this.

 

woooohooooo thanks for the business

 

You only need spacers for the front for clearance. What wheels are you running? offset/width and tires? You may not need the spacers.
