Searching for a subtly lowered ride height for your car? ST Sport Springs are made for it! With our ST Sport Springs, you can equip your car with a spring kit that has been developed specifically for your vehicle and designed to fit your original shocks to achieve a slightly lowered look. Our wide range of ST Sport Springs offer more than 1,000 applications and we are one of the few lowering spring manufacturers on the market that have also developed for numerous vehicles with electronic dampers. Our ST Sport Springs are designed to work in conjunction with your factory dampers. Each set is matched to your particular vehicle to ensure your suspension continues to function properly. At ST suspensions, your driving experience is the main focus when it comes to our products. That is why we select vehicle specific spring rates in each ST Sport Spring kit to perfectly match your original dampers. Our ST Sport Springs are made out of chrome silicon steel to guarantee a long lasting and quality driving experience. You will not only benefit from a lowered center of gravity and more direct handling but also improved steering and more stability during cornering because the vehicle's body roll is reduced. ST suspensions springs are constructed to OEM quality standards. They are made of high strength chrome silicon steel in a cold winding process then multi-tempered and have a final epoxy coating. This process helps resistance to different weather conditions. The high strength ST spring steel also ensures that our ST springs are block resistant and the springs do not sag.
ST Sport Springs work in conjunction with your factory dampers. Each set is matched to your particular application to ensure your suspension continues to function properly, providing percise lowering and a greatly improved appearance.

ST Sport-tech Lowering Springs Mini R50 (incl. Conv./Cooper/Cooper S) - 65431 FAQ
The maker's installation guide is on this page — see Installation guide under the part details for the step-by-step and the torque figures. Work on level ground with the car properly supported, and torque every fastener to the maker's figure. If the job is beyond your tools, any shop that does this kind of work can fit it.
Lowering springs work with the stock shocks when the drop is mild, but a shorter spring makes the shock work harder, so many drivers pair them with shocks made for lowered cars. Shocks that are already worn should be replaced at the same time.
Yes. Lowering changes camber and toe, so align the car after the springs have settled.
The drop is set by the spring and is listed by the maker for each car; see the Part details above when it is stated. The car settles a little further over the first drives.
Lowering springs are firmer than stock but keep most of the comfort. How much firmer depends on the spring rate and the shocks they are paired with.
It needs a spring compressor and jack stands; without both, a shop can fit them. Torque the suspension bolts with the car sitting at ride height, not hanging in the air.

Install and care: lowering springs
Before you start
- Have a spring compressor, jack stands and a torque wrench on hand.
- Check the shocks while the struts are apart; worn ones go in now, not later.
Do
- Torque the suspension bolts with the car at ride height.
- Re-check the ride height and the alignment once the springs have settled.
Don't
- Don't cut or heat a spring to lower it further.
- Don't tighten the bushing bolts with the suspension hanging.
