Magnetic ride question

Damnit. I made that mistake before. You're right its a valve, no MR fluid for my car.

Point still stands for race cars.

I was really impressed with MRC in a Z51 package C7 at the track. It felt really well damped over small bumps and even gator strips. If they offered it as, say, a $3k option on the FR-S, I would have strongly considered it.

Shenanigans.

If there's a rough slow portion of the track they would absolutely soften the damping to keep the tires in contact and maximize mechanical grip, probably in a rough straightaway as well, then crank up the stiffness on the smooth high speed stuff to maintain flatness for aerodynamics and to keep all four tires evenly loaded. And like mentioned by RB being able to go a click soft or stiff on one end would be fantastic for managing balance, really take a load off the driver if they missed something in the rest of the setup for long sprints. Like he said if it was useful it'd be on Indycars already and you'd see testing and advertising for it everywhere.

There was a push by @DougW and some wacky dutchmen to build a better Damptronic system. I don't believe the project ever finished for the BRZ, but aftermarket options exist for Porsche's PASM system.

LINK to one of his threads

My understanding of PASM is that it has ride height (for adaptive air systems) and damper bleed valve control. It uses driver inputs (cockpit buttons), a host of sensors (linear position sensors, accelerometers, gyroscopes), and parameters accessed from the CAN bus (vehicle speed, steering angle, estimated engine torque, brake pressure, etc). I don't know how detailed their system goes... but it's probably pretty fancy, given the $2-4k price bump for those options.

I believe the main reason MR isn't used on race cars is that it is not allowed by the rules. I'm not aware of any road race series that allows active or semi active suspensions.

Also, as I believe you mentioned, there were some heat issues early on; not sure if they fixed that in the latest generations.

MagneShocks sell a setup for racing, but its like $15K!

Anyway, the tests I've read say MR works well on production performance cars on and off the track. I'd order it if I were buying a new car like the Camaro, Corvette or Mustang...

Race rules didn't stop F1 team we worked with back in the day when they could run whatever they wanted during testing. They still decided to toss it in the trash.

If there was a benefit the teams would push for it but no one even talks about it so the rules stay the same. Although F1 is potentially on the brink of reintroducing an active system for 2017 or '18, MR is not what they'll be using.

Yeah it was a CTS or ATS I cant remember it was a while ago. Its also in the yukon's and I think its an option on some ZL1 camaros.
