I would buy a set at that price.

These guys have been around for a while, and their Grey Evo has been running Fortune setup with great success!!

I may be interested in a set for the B14 chassis

I see it first hand all the time when i stop in there i have even helped before lol. every unit is fully assembled and dynoed in shop, this is the only reasonably priced coilover i have ever seen that dynos EVERY single damper before it leaves the shop. all the budget companies just send you crap straight from china.

here is a little look at the headquarters here in Virginia

here are some dyno graphs I made to show different dampers. I know this is mean much to most of you but I wanted to share anyways. You rarely see shock dynos because most companies want to keep them secret. Some of the reasons for this is when dynoed all the cheap brands show poor performance especially when ran to a high temp, another main reason is that most adjustable coilovers dont actually adjust when you turn the knob. you can clearly see in the original graphs I posted that the 500 damper shows a clear 10-50lbs change per 5 clicks of the 30point click-able adjuster.

this one shows the Progress against the Fortune 500 and 510


This shows the same info but also shows BC racing, and stance to illustrate what the budget Chinese dampers dyno like.

Any chance you could come up with a little bit slower plot? data above about 3"/sec is only really useful for tuning ride quality.

It doesn't look like there's much adjustment for the 500s, honestly they only look a little better than the typical fashion/drift coilover. The 510s have a legit looking force curve, first i've ever seen those.

I don't understand what you mean, could you elaborate?
The graph clearly shows below 3"/sec and shows that the 500's has more low speed rebound force than progress,bc,and stance. The progress and 510 damper is more digressive but they also cost much more. The 500 is valved and better suited for the higher spring rates I want to run.
The other graph which shows the 500 at 5 click intervals shows a ton of adjustment, whereas the progress damper has zero adjustment and most of the cheap brands don't actually adjust when you turn the knob. Also, remember the 500 is intended to be an all-round performer and the best compromise for streetabilty and high performance. They can be valved differently if you want a full race setup or you can upgrade to the 510 which as you can see has great low speed force and is very digressive. graphs clearly showed that they are better than 2 other brands of "fashion" coilovers by a good margin and more than comparable to the progress units. I have also dynoed ksport and some other brands and they perform as terribly when compared to fortune or progress.

I started design of the rear top hats and front camber plates today and will hopefully have a really strong simple setup that you guys will like. Only thing I'm trying to still decide on is what to do about the rear sway bar.. maybe ill make a bracket and new endlinks that will relocate the sway bar attachment point from the shock to the spindle.. some of you with after market sway bars may already have something like this.

I would not worry about a stock sway bar mounting point. Most people who run coil overs run a after market bar which mounts different any way. You could also do the threaded collar like d2/ksport/bc do. Their mounting point just threads on the to the rear strut and can be removed. I might have some laying around.

Here's why I feel that they don't have much range of adjustment. Koni Sports have a lot of adjustment.
