BC Racing DS Coilovers - Anyone Running These?

[Octane11]

I was ready to order the BR Series from BC Racing, but in reading about the DS series, I started to research and can't seem to find any Gen 2 or any other Gen Vipers that are running the DS instead of the BR. The DS uses a digressive piston that should help with dampening at low and high piston velocities. It costs a few hundred more, but I'm wondering if anyhone has used them and what their experience was.
Been trying to reach BC Racing for 3 days and can't get a hold of anyone. The web chat option gives me generic answers. Any insight would be appreciated.

I've found the BC product on the low end of the suspension market. It does give you the ability to lower your car but the shock does not really control the spring very well and
tends to be over sprung and under dampend. Product support is poor. A much better choice than Aladan's. You get what you pay for.

The best choices for the Viper in my experience are MCS, Koni, Penske and KW. I prefer MCS as the shocks can be built for the spring rates you are going to use, which gives you more adjustability either way. They also have several options, single, double and 3 way adjustable to suit your application and budget.

If you have different spring rates options then how can it be oversprung? And if you have dampening options that you can adjust whenever, how that would make it under-dampened? I'm not saying BC is best for track use, but for my DD (knock on wood) they've lasted much longer than my skunk2s, and I haven't had any premature wear on anything that I can see and I've put probably 100,000 miles on them so far.

If you choose the spring rates that are best for your setup, then that is the way to go. The problem is the damping on these shocks is pretty crude and they don't control the spring well, so you need to run a heavier spring rate so everything works. That's why I say oversprung and underdampend. Also, the rear shock is limited in travel, more so when you lower
the car, which can be dangerous.

Don't get me wrong, I'm not saying this is a bad product. They even say its not really a track system and things may have changed some since when I worked with them to develop this system. Its an option for those who need new shocks and/or want some adjustability.

I can tell you, if you are able to drive a car even with a base MCS, or properly valved Penske system, you will know what I'm talking about. Its night and day.

Just my experience, your may differ!
