Ring and Pinion – What is REM Treatment?

REM treatment is a proprietary process which eliminates the imperfections left over by the machining process. In very simplified terms, the “peaks” left on metal parts by various manufacturing processes are removed using vibratory equipment in conjunction with patented solutions to speed up the process.

Although the result of the REM(tm) process is a beautiful finish, it is Important to realize that the system does not polish the part. The process involves two steps. The first, referred to as the refinement process involves a chemical interaction on the surface of the part. A soft, thin (one micron) film is formed on the surface of the part. The part interacts with the ceramic media in a special vibratory tub, this film is physically removed from the “peaks” of the processed part and the “valleys” are unaffected. The chemically induced film re-forms only at the peaks that are interacting with the vibratory media, and the process repeats itself. Over time, the peaks are removed, leaving only the valleys, producing the improved micro finish. The second step is referred to as the burnish process. After the required micro finish is achieved, a mild alkaline mixture is introduced. After a relatively short period a polished, chrome-like finish is produced. In addition to the polishing effects, this step effectively removes all traces of the film formation from the refinement process.

The result is a much more uniform surface that provides many impressive benefits for motorsports, including:
-Reduced Friction
-Lower Operating Temperatures
-Extended Component Life
-Reduced Noise
-Increased Efficiency
-More Power To The Ground

VAC Notes:
Summary: After a few years of brutal abuse and testing, the VF620 kit is finally available for sale! Let me say, it was well worth the wait. The VF620 kit transformed an already excellent car to a precise weapon. Absolute stock driveability with gobs of linear and predictable power = the ability to decimate almost all challengers on the street, strip or road course. Seriously, it’s that good – even BMW would approve 😉

We installed the VF620 our 2008 E92 a day before Bimmerfest East and it has run flawlessly ever since. We set a world record on the dragstrip and gave it hell on our local circuits. While we build a lot of track specific cars, our E92 M3 was built as a daily driver that can run really well on any given track. So far, the car has exceeded all expectations and we are just getting started. Even with street pads, a decent suspension and street tires (R888) the car blew us away at NJMP. The power delivery was ideal for the road course, and the kit simply delivered lap after lap. No heat problems, no hiccups, no issues. 2012 is going to be a huge year for our VF Supercharged M3!

Tuning: VF brought all tuning in house for their BMW kits to ensure the best possible calibrations are released with the kit. The results of this hard work really show, as the car exceeds any expectation we had. Wow!

VF’s Vorsteiner car: We also had the pleasure of driving VF’s Vorsteiner car for 2 months. Prior to joining us, the car was hammered by MMA fighters, celebrities and race car drivers on the Bull Run and Gold Rush rallies…so we were a bit worried that it would give us trouble. We were wrong, the car performed flawlessly and kept asking for more. I think it had 35k VERY HARD supercharged miles when it arrived in Philadelphia…but it performed like new.

Experience: We have installed, serviced and diagnosed many supercharger kits over the years, and VF kits always seem to shine. They are simple and effective…just how we like them. A beastly 6sp VF supercharged 540 Touring, 700hp VF Supercharged MCoupe and a VF Supercharged 740 were in the shop a week before the VF620 kit and VF/Vorsteiner green car arrived in Philly.
