Anyone have any first hand experience with the Drummond MotorSport (DMS) shocks/coilovers ?

They have a 40mm and 50mm application for our FD RX7's.

The 50mm is independently double adjustable for compression and rebound, and is only $3325.

TIA,

They are very good, just abit on the expensive side. A local impreza DMS 50mm owner said it doens't have enough rebound adjustment range, since it's designed for rally use.

I believe the M2 stuff was "advance design" struts found here:

If you check the DMS site, they have rally, street, and race versions of struts.

M2 sold DMS products after they sold the Advance Design products.

Did M2 abandon "Advance Design (AD)" from an engineering, customer service, or profit perspective ?

I'm thinking about the "AD" double-adjustable (DA) struts . . .

I don't know whether M2 "abandoned" AD, AD abandoned M2, or there was some other cause for the switch. Maybe someone that knows more about the business relationship will shed some light on it...

I have the 50mm shocks purchased several years ago. Yes, they're seperately adjustable for compression and rebound. They're valved for spring rates front and rear 550lb F/ 450lb R. My installation uses the Ground Control top hats. The seperate adjustments are nice to play with but are definitely overkill for street use and probably overkill for track events unless you can quickly zero in on "the" setup. I do play with the adjustments, however, and it is educational.

I had to have one shock rebuilt, but that was due to a nick on the shaft which tore an internal seal and caused it to leak. I probably caused the nick on installation. Rebuild cost, including shipping to Canada and back, was about $400. I installed dust boots to help keep the shaft and top of the shock clean.

They've seen some hard track use and light street use. Overall I'm happy with the shocks.
