Ehh just more stuff to break IMHO. May be great may not be, but I do know Petter didnt like it at all after they developed an active suspension for him for 3 years. He used it for one event and said scrap it.

I'm a fan of use what you have. If people have been able to push these and several other AWD cars to there limits w/o it, I'm not willing to push reliablity for it. I share the same feelings just one more thing to break, if it was up to me I'd have no power nothing on my car or cruise control for that matter. But oh well I'll deal with the extras. What was so wrong with lower and upper control arms and a spring between them anyway?

I saw that in Autoweek and another tuner mag this week and am considering it for installation when it does come out. The ability to provide a softer ride for daily driving and switch modes to better than stock for track days is what attracts me to it.

Only time will tell for reliability, but it doesn't seem to have excessive parts associated with it. My only concern would be long term reliability and rebuildability (is that a word??). Having owned two other vehicles with "acitve" suspensions, I know the struts are not cheap to replace.

Oh well...just have to wait and see. Since mine is a daily driver, anything I can get to make the ride smoother on the road without compromising track performance is a definite plus in my book. Have to wait to see the tuners test it out some more.

Macpherson struts are better for dirt rally and you have to use the same mounting points on the wrc car as the actual car. And since subaru concentrates more on the dirt rallys we dont get a double wishbone suspension.

Right now, its the idea behind it that is special. If they don't work well now, eventually the technology will catch up and they will work as well or better than what we have today. I've only been thinking about this type of system for years but never had the know-how to develop an idea.

Anyway, I like the idea and I like the technology. Hey, you never know, this design might work well, time will tell as soon as people start using them.

*Edit
Pruned some crap out of my post :D

I was just wondering why a strut desing works better on dirt than a properly designed a arm system.

Easier to get more travel etc... Dont know exactly but through many years of rallying mac struts have proven to do better in the dirt then double wishbone suspesions. Subaru is slow on tarmac rallies due to the tires, suspension and the driver. In the dirt they are fast because of the tires, suspension and the driver. Rarely is somthing best for 2 things so you make compromises.

And yes they are legal for autox but only SM I believe. They may or may not be legal for sp Id have to read up on that.

You can find autox rules at moutons.org If its not specifically listed its illegal.

Air bag suspentions have been considered the premium package in heavy trucks for years. Million mile design life. Reliability can be there, but it depends on the execution.

:confused: Sorry I must be lost. Why are you talking about airbag suspensions? I didnt see anyone mention the praxis system.

My oops. The both start with "P" and both have an electronic brain. I stand by my statement that it's the engineering and quality of the components that determine the life of the system.

Alex, just curious, did Petter say what conditions he did not like to use the Active suspension in? Or was it just all conditions?

I like the concept and I hope it can be developed to its full potential.

Prodrive was developing it for tarmac rallys for 3 years or so. Petter used it in one last year and hasnt used it since. He didnt hate it but he didnt feel it was any faster then the normal suspension that they had been using. And if the mechanical couterpart performs just as well there is no reason to complicate things more all that will do is mess with his feel and possibly fail so he just scrapped it.

It was supposed to be significantly faster the the normal suspension and it wasnt.

well I can imagine that someone who races day in and day out would not like to change the way anything feels right in the middle of a race season, even if once he got used to it, it would be a net positive gain. But I dont think that there can even be any argument that an active suspension is not a significant advantage to conventional suspension, jeez, thats why they banned it in F1!!:confused1

As far as more things to break, well I suppose we will see, though you can make this argument with just about anything, I guess a sixth gear is just one more thing to break. To me that not enough reason to avoid benifiting from new technology, this is the way things are heading and I belive you will see this more and more on cars to come and in the aftermarket, guess I'll be the guinea pig!

Im going to guess the tech they were using on f1 cars that was banned was a bit more advanced then what they use in wrc. Even if it isnt its a bit harder to get an active suspension to work properly on a rally then on a smooth predictable race track that you would see in f1. And its not so much that it may break but also since its ever changing theres a chance it reacts differently at different times. Thats the same reason I hate the automode on the dccd I will take one turn fine the next one Im sideways because its varying continuously.

I wasnt trying to say you shouldnt get it just voicing my opinion that im not all that excited about it. Id rather have a $3k dollar conventional suspension and yes my car is a daily driver. Computer control usually takes fun out of driving(for me anyways) and Id like to keep it to a minimum on my car.

But by all means get the suspension if you want it, its just not for ME.;)

Okay, not 100% STI related
You're right... not even close. Sorry to catch this late. Sounds like a good thread for the suspension forum!

Huh?? Petter won in Corsica and only Loeb put up more points in the asphalt rallies this year in the Citroen - an asphalt specialist in an asphalt specialist car that are trying to adapt to gravel. That doesn't sound slow to me!!

Petter's asphalt performance basically won the world championship for him.

The big advantage active had in F1 was maintaining a perfect level ride height, thereby maximizing aerodynamic grip that F1 cars are so dependent on. That's not nearly as important on a rally car - especially in the dirt.

Petter won in the rain. Pirelli's are actually good in the rain and rain changes everything. Petter prays for rain at tarmac rallies. Hell he was quoted saying "If it rains I will win" period.
