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.
