ST is owned by KW. Are there better systems out there? Of course. Are there worse systems out there? I do believe so. Is the car going to drive like a Cadillac? No, and it never did.

Would think they are similar to the other units in that price range and if you do some searches there are threads here about them.

I think several people are running those coilovers on the forum. You might have more luck finding reviews by searching for ST-X coilovers. Here’s one of the more informative threads for those coilovers on a 2nd gen: https://www.northamericanmotoring.co...-pictures.html

Here’s my experience and with ST’s, although on a 1st gen and ST-XTA’s. The ST-XTA’s handle a lot better and are less harsh than stock, even with the coilovers lowered a fair amount. The difference between the X and XTA coilovers are adjustable damping, linear springs, and adjustable front camber plates. Other than height, my XTA’s are set as installed straight from the box.

As far as I know, the only difference between ST-X’s and KW v1’s are the what the shock bodies are made of, and the warranty. If you drive a lot in wet or snowy areas and plan to keep your car for a long time, I would think twice on the ST’s because they only have galvanized bodies vs stainless steel/Inox used for the KW’s. If your using factory 17’s, you’ll probably have to run at least a 5mm spacer to clear the lower spring perch on the front. This was also the case with the XTA’s, even with the skinnier linear springs.

Also, ST usually has a rebate/sale, or two, every year and future use gift cards are sometimes included by ECS Tuning at the same time increasing the savings.

We are running a $50 ECS Gift card right now on these and of course in the contiguous USA free shipping. EuroSport Tuning is one of our distributors in Canada if you want go through them. Just tell them you want some ECS Stuff.

Can you please post your finding, im experiencing unknown clunk whenever i turn the wheel in all directions during low speed especially when put in reverse, i thought maybe due to the suspension Perch when i replace it with KONI where they are well known to seperate from the tube, replaced the lower control arm bushing when it was 40K miles and only has 69k now, i even changed the control arm link lubricate all rubber connections, installed plates and braces and still makes weird noise, my last option is to repalce the hub/bearing, the noise is coming from the right front. One thing i noticed is both top rear holes where the towe mount are getting bigger or wider, with the brace helps? I just installed the brace this year and this car is 2002 MCS.
Thank you

Ok, great. Thanks for the order.

Yep, i had mine clunk and 9 times out of 10 it was the outer tie rod. Both on my R56 and my R52. Just the nature of the MINI suspension.

If your tie rod is the culprit have you notice your tire wearing out? All these years of driving whenever the tie rod, ball joint are going bad the tire wear out unevenly, tie rod and ball joints are enclosed and lubricated unless the boot is ripped and chances the grease escaped and causing metal to metal and causing to clunky noise, my 02 MCS was making noise when the lower control arm bushing was bad only when driving on bumpy road and small potholes but already changed. I suspected mine was the hub bearing but i want to confirm first.

When ball joint going bad you noticed when turning especially when you hit a little bump or small potholes the car will pull/ slide.. My R55 is doing this now...i thought because the tire was slightly bald so i replaced all tires and still does pull when turning either directions but no clunking sounds.
