Anyone using these. I have a 18 6 2.5t. Any input regarding ride quality, extra hardware needed and anything else would be greatly appreciated. TIA

Cork sport WILL give a noticeably firmer ride quality.
These spring are designed for sportier driving style. So if your Mazda is a Dailey driver just consider that.
You can contact them and the specification for the spring rate and comp[are to other offering spring kits

The other thing is Cork sport end ride height or installed height is one of the lowest available.

You may want to contact Racing Beat directly and see if they have a spring set that will work that they have not listed yet?
Not as low after install and no as creature comfort absent as Cork sport.

I have tried Cork Sport, Racing Beat and also one no name performance spring and Ebach and over all Racing Beat was the best overall for a street driven and occasional spirited driving. Measuring on the D-Pic for G-force the Racing Beat actually did better then the Cork Sport. Which also why in the end I choose to use Racing beat springs.

My end dampeners will actually be Cork Sport dampener front and rear with racing beat Springs.

There is nothing else needed for any basic coil spring replacements.
