We've been huge advocates of Fortune Auto for a few simple reasons. Personally speaking, I'm not into the whole stance thing to be honest or being slammed. I also prefer performance (function) first, but they've really nailed the capability to do both. We've become a master dealer of there's and have a MASSIVE amount of happy customers that are Fortune Auto lifers now.
-Each set is hand-built but a team of engineers
-The ideology behind each set is that you can send them in to be rebuilt or modified (you can add Swift Springs or turn them into 2-way Dreadnought's after you've purchased them)
-Everyone has different driving styles/goals, Fortune Auto can be fully customized to the customer spec (spring rate, many options can be added like radial bearing mounts)
-On that note, Radial Bearing Mounts make a HUGE difference for a daily drive. We have them on our shop cars here (DSG edition FA500's and standard 500's) fully done up. They make no sounds that you typically associate with coilovers (clunks and vibrations), extremely smooth (my gf doesn't complain, first sign these are awesome). But when you hammer it in a turn you know you have some serious performance under you, it's actually pretty mind blowing
-My biggest point price versus quality. They're extremely reasonably priced and easily comparable to coilovers that are 2x the price. There aren't any other fully customizable coilovers that are built nearly as good as Fortune Auto, especially at this price point.
Look at a cutaway of the Gen5, they're built like a tank:
-Multiple options available to suit whatever application, 500 series (daily + occasional track), 510 pure track, 2-way (serious track), 3-way (professional series)
