Must be fairly new, could only find one supplier online. They are the street performance model which doesn't have any dampening adjustment. They look ok, but For the price I think you can find better.

I have been looking at these intensely. Actually, I was extremely close on pulling the trigger on a set of custom Bilstein B14 for my car until I found these.

H&R coilovers often use Bilstein damper components and then valve the dampers for their springs. This is the impression I am getting from my searches. Sometimes the damper tube even says Bilstein on it.

In any case, you are getting a monotube system which is superior to traditional twin tube systems in theory. Also, the lack of adjustability is not necessarily a bad thing. It means you can't mess with the valving relative to the spring.

Cheaper coilovers with adjustable dampers seem to sort of throw you a set of shocks and dampers and leave you to figure out what is best. A system whose dampers are valved for its particular springs seems to be ideal.

For the same reason, mixing and matching separate shocks and lowering springs is cheaper and not quite as good as the same system with the shocks having been valved (using a shock dyno) for the chosen spring. Improvements in both ride quality and handling result from proper valving.

I think I'm going to get a set of the H&R soon myself.

Here goes nothing ordered my set for a great deal. H&r is normally rock solid. I think I will be happy.

You fully understand whats going on. These MUST be good. Neither H&R or Bilstein make junk... and tune a combo for each other will be magic. Someone send me the link...I'm interested in pricing.

Tell us more!

How does the ride and handling change from FE2?
What kind of roads are there where you live?
What height setting are you using?
Did you get the car corner-weighted (opinions on doing this)?

I'm waiting on mine to be shipped now and am like a kid waiting for Christmas.

Also, KW V3 coilovers are twin tube. Twin tube stuff is generally more comfortable but oil emulsification/bubbling (and damper wear) is more inherent to this method (a piston sliding around in the oil and then a tube sliding inside another tube in the same oil). In theory, this means a twin tube design would not last as long as a monotube system (just one piston in one tube full of oil). In practice, I don't know. KW has an amazing reputation everywhere I look.

In both monotube and twin tube systems, a big jump in performance happens when the shocks are gas-charged. Gas charging increases the pressure inside the shock, making it harder for the oil to emulsify/bubble from heat. Shock oil emulsification also turns the damping to crap since the oil/oil bubble mixture flows through the shock piston's valves too easily and let's the spring go through it's natural bouncing cycles.

Can you give any confirmation on who produces the dampers for these Coilovers? Ride quality?

I got them from Race Consulting Agency

Great customer service so far. I called to order and they bumped down the price a little more. I have also been calling compulsively and asking questions, as is my nature. According to the tracking info, I should be getting the coilovers on Monday, which happens to be my birthday!
