I know at least some other manufacturers are on the grid too; SACHS to name one.

Ferrari I think uses Sachs, McLaren had always used Bilstein or Koni.

I can say that its pretty well known we worked with McLaren on the first inerter in 2005. Like I said before, some companies pay to have their name on the car and nothing else.

Sorry I was going off articles like this. Btw just out of curiosity have inerters found their way into sub racing applications yet?

I definitely know Ferrari did from when Schumacher was driving for them at least up until Alonso in 2010 as well. I believe they still do, but not 100% on that. BMW Sauber runs them now, and Merecedes did in the 90s (not sure if that has changed though). They also supply clutches to many of the teams now.

Sorry to threadjack though. Back to the Penske discussion!

Inerters are required equipment to have any chance in pro drag racing. World challenge banned them. Tudor banned them. I'm sure we'll get them on rally cars now that we're moving that way. Indycars run them every weekend. Rich guys can have them if they want, I believe the Roadster Shop Rampage Camaro will have inerters.

Mechanical inerters require a ball screw which is part of why its so expensive. We're working on a fluid inerter which would be a lot cheaper, so it can get banned at the lower levels of racing too.

Ofcourse. Get ready to put that kindey up on med-ebay.

So all this time i see ferrari has electromagnetic dampers and the new z/28 rolls around with them quoting thousands of ajustments every second. Whats stopping someone from asking you guys to build one of those Ryan? Apart from the possible required materials.

Side note: For some reason i keep seeing this gps enabled suspension system, having a digital map of the course in its mind, taking into acount the corners, entrance and exit speed and lateral grip thus adjusting accordingly, being a very interestingly potent thing.

Sounds expensive but thats not what we're here for either lol

[RBbugBITme]

They're garbage. Developed them with an F1 team first back in the day and found it wasn't worth it. The metal in the fluid tears everything apart so the shocks don't last and the fluid is too expensive to rebuild every week. They're also reactionary. They quote how fast they react because they can't predict the bump your about to hit, they can just respond to the input after its too late. There is an inherent flaw in that.

@cdrazic93 while that sounds cool, I don't think a GPS with even the best of the best refresh rate could measure the nuances of track elevation changes, not to mention other things that race conditions (wet/dry and temps), tire compound temps, tire pressure, etc

Although originally legal when your product was first released, they have been banned since at least 2013 season as per rule 14.11.4. and 14.11.11.

In any event, I'm excited about the news of these products coming to market for the BRZ/FRS/GT86!

Rule 14.11.1 Dampers are an open development component, provided they otherwise comply with these Rules.

14.11.4 No front or rear third dampers, inerters or any other device are permitted nor any modification to the manufacturer supplied parts.

14.11.11. No independent inerters or mass dampers are permitted.

Basically by the time they wanted to ban them we sold so many too many teams would have had expensive piles of scrap so the corner damper/inerter hybrid is legal because corner dampers are open for development.

[Hoosier Daddy]

Well I'll be.

Why didn't IndyCar just ammend 14.11.3 to say "Each corner must have one damper and one spring. Helper springs, bump rubbers and
packers, as well as inerters are permitted..."

[RBbugBITme]

Probably because they wanted to make sure everything from an inerter was contained inside the damper body.
