the best information there seems to be about them is ~$3000 and they supposedly ROCK.

please update us, when you get some more details, Chaste.

Expensive ... but not that outragious considering their range ... if they work ... compared to other top of the line coil overs. Great for the well heeled weekend warrior ...

I guess these are the civilian version of what Solberg used in Corsica (Catalunya?) ...

Hopefully Caste Automotive will be able to give us some driving impressions ...

Hmmm seems like the same technology that GM is using for some cadillacs and 50th anniversary vettes. If it is as good, it is AWESOME.

Will do we will be getting all the information we are meeting with the engineers tomorrow so hopefully they will be able to shed some light on this. We have a lot of new products to offer since we have come across a few new manufacturers on this trip. We will release a carbon fiber prop shaft when we return.

I believe the vette dampers use an electric field to change the viscosity of the oil passing though unchanged piston orifices. the Prodrive units have a fast mechanical valve that changes the orifice size according to the info the computer gets from the two (wheel and body) accelerometers on each strut.

For $3000, that is mighty impressive suspension technology for the STi. It seems they should do well in the dailydriver/track/rallycross multirole stuff that alot of STi owners do.

I drove the 50th anniv. vette over the holiday, nice adjustable dampers. They are not "active" though, just 2 settings (sport and comfort). Not the same as this new prodrive setup.

Cheers,
Jeff

The praxis is air and requires a compresser and tank, it also does not change damping by it self. The good side of the praxis is you can change ride hight and damping, from a track setting to a rally x setting. Thies will give you a better set up for the track but will not have the abilty to adjust for different conditions like the praxis will. Also I would be surprised if prodrive only charges $3k for thies.

Hmmm I got my info from C&D article how the 50th vette changed dampening 1xx times a second through the magnetic sys.

I must be mistaken then. It may perform adjustments constantly under each of the "macro" settings with the settings purpose in mind.

Thanks for the info. It does make sense.

Are there any specific questions that I can answer for you guys?

Basic information…
Target releases date – Early Summer
Target price – Less than $3000
Application – STi and WRX

Currently there are 2 vehicles in the United States running on this suspension.
After the first sets hit the market we will be looking into making the Active Shock Suspension for other vehicles.

This suspension was designed for the road version STi/WRX and is not the same suspension used in our Group N or Open Class Rally cars.

Kind Regards
Dan Antonielli

Will they work for the Wgn ...

Can one adjust the heights ...

Can they be biased one way or the other ...

Do you feel this is going to be the "perfect" solution for the "weekend warrior" who would like a bit of comfort driving to work ... but can hope to be decently competitive driving in AutoX (with the proper tires) on the weekend.

makofoto...

The current prototypes are on STi’s… No wagons yet.
There are sensors in all 4 struts and a central unit.
The algorithm combined with the information receved from the sensors should be able to adjust to accommodate the wagons handling characteristics.
But I am not 100% sure due solely to the fact that it has not been tested on a wagon yet.

We are still debating the inclusion of height adjustment (coilovers)
The current prototypes are coilovers… so I think that is what we are settling on.
I will know for sure next month.

Our intentions in the future are to offer a dash module that will give the driver the ability to determine how the suspension reacts.

On paper this seems to be the ultimate solution but until I have a chance to experience this suspension myself I can’t give you an honest answer.

How much will these weigh compared to the stock struts?

Also, I put in a vote for making the coilovers!

Yes the carbon shaft is for both 6 and 5 speed versions. We have just been over to have a look and they are ready for production.

On the active suspension, we found out some of the details but I think that Dan can release the information since he has the test mules.

We saw the S10 WRC car getting a shake down for Monte Carlo and the new engine and trans package we will post pictures over the weekend.

Hopefully this will be height adjustable.

It will be one of my last two prodrive products.

Going for seats, then the ACT.
