      Mountune ST Springs

      Great. Handling much better, lot less body roll and ride tad firmer. Excellent product. And looks a lot better too.

      Perfect Springs for a Daily.

      Firstly the quality and fitment of the Mountune springs is perfect, as good as OEM - Which really is testament to Mountune's high quality and one of the reasons I am so committed to the company; you get what you pay for! Once fitted there is clearly a noticeable drop in ride-height over standard, but not as big of a drop compared to some other springs - Which given my car is a daily driver was definitely something I was mindful of when deliberating options. That said, the car sits a lot better than standard, especially with the 12.5mm front spacers/17.5mm rear spacers which I fitted at the same time, and in my opinion is how the MK4 Focus ST should have been supplied from Ford. In terms of ride quality, I would say the overall feeling of stiffness is roughly 10% stiffer from stock, so slightly firmer but not enough to compromise the daily comfort of the car. I have noticed that the feeling of stiffness in the different adaptive damping modes (Normal/Sport/Track with performance pack) is definitely a smaller difference now in each mode, but given the adaptive damping only effects the rebound/compression of the shocks, with stiffer springs this is to be expected. Performance wise, the car feels much more planted now when you push on and load the suspension in a corner, the front end just feels flatter and this definitely gives you much more confidence to lean on the car in the corners, so definitely a huge improvement! If you are looking for some lowering springs that offer much improved handling and looks, without compromising the comfort or practicality of the car too much then these are definitely a great option and given the high quality and affordability should definitely be a the top of your list.
