"his used to be part of the suspension upgrade FAQ but now that we have more room at the top, giving it its own slot might not be a bad idea.
The rules.
The first rule of the suspension forum is: Do not talk about S-techs.

There is a good reason for this being on Nasioc. The s-techs drop you so far that you are permanently on the bump stops. The options i list below all come with bump stop replacements. Unless you run ohlins, have cut your bumpstops (and even then you still wont have much bump travel) or like the feeling of having no bump travel then any of the options below will be better.
That being said. I am researching some options for myself.
RCE Yellows - Harder and lower then the blacks. May look cooler but if you drive your car in the winter you may want the extra ride height and comfort the blacks offer. I personally would buy blacks if i had to choose between the yellows and the blacks but its purely up to you.
RCE Blacks - Apparently a very good option based on my research and i will likely be pairing them with ohlins. Little softer then the yellows with a smaller drop
Prodrives - Best option for comfort on the stock struts. Not a huge increase in stiffness or performance.
Thats how i feel about em.
