The answer is Yes and No 
IIRC
Prodrive don't actualy make the Springs. Prodrive give the specifications to Eibach etc and they make them. Whereas the Eibachs will use there own spec's for there own labelled product.
So the "Eibach" STi spring kit will NOT be exactly same as the "Prodrive" STi spring kit made by Eibach
In the Prodrive kit i beleive you also get replacement bump stops
an Warranty

The Prodrive kit was developed and is manufactured by Eibach. There are two differences between them when shipped:
1) Prodrive ones come in a Prodrive box, Eibach ones in an Eibach box
2) Prodrive ones are red, Eibach's are black
1) Prodrive ones come in a Prodrive box, Eibach ones in an Eibach box

Before this gets into 'I read it on Scoobynet so it must be right' (22B, 350bhp as std anyone..) I would like to point out that you have been mislead, they are completely different rates and lenghts. They are made by Eibach, but there the similarity ends.
The guys from Eibach UK were absolutely gobsmacked by the difference the kit makes to the STi, but that was the first time they had driven a car with a kit that had been developed by us in the UK.

No, that's wrong again! (22B has 375bhp now!!)
The Eibach springs have completely different rates, achieve different rideheights and don't have bumpstops for the cars fitted with monotube dampers like the STi or 05MY WRX.

I'll get me coat and go and start ugly rumours elsewhere
While you're on the line, any chance of you guys coming up with some tyre pressure settings for the PFF7's you are selling us all? At the moment you only offer them for P-Zero Neros (2.3 front, 2.1 rear, I think) - whereas most of us don't like that tyre. I wouldn't suggest you do all possible tyres, but the common ones (like Goodyear Eagle GS-D3, Toyo Proxes T1-S and T1-R) would be useful!

Supply me a set of each tyre and we may do
To be honest, it really comes down to personal preference. I would suggest starting at the pressures you list and then adjusting them slightly to suit your own tastes. As a generalisation, when we've tried heavily directional tyres like the T1-S they seem to need more pressure to get good steering feel but this affects the ride. Only you can decide whether you want the ride quality or steering feel to be optimised. When doing this sort of exercise it is important to start from a known reference though, ie set the pressures with a gauge you are happy with and can use when you need to and go up and down by 1 or 2 psi at a time. Remember that as the tyre warms up, either by driving or a change in ambient temperature, the pressure changes. As an example, if the pressures are measured in the morning on a car that has been sat outside, they will be less than if you check them at a motorway service area. We use our workshop temperature as a control as it stays reasonably constant.

No, we are still waiting for the initial stock to be produced by our supplier. When they arrive, they will be checked to make sure they do what we want and then they will be out to Subaru. Week 12 was the latest estimate/German promise (note that a German promise may only be very slightly more believable than an Italian one )

Thanks for the info - it's not far off what I've done to date with the 3 sets I've used so that's good. What's ride quality, by the way, and why should I worry about it? While I'm on the topic, why does my MY03 STi PPP eat front inside corners? I stretch my tyre by swapping end-for-end at half-life, but I'm wondering if higher pressure settings might help a little here?

Quite a lot of load is put on the inside edge of the tyres under heavy braking so my suggestion would be to brake less and go round the corners faster.........
Check the gemetry would be the obvious route making sure that you have no toe-out.

Or is this perhaps a factor in inside corner wear? Does toe-in cause understeer, so now I've got toe-out?
I suspect it's one of those things I have to live with - even the chaps at Cotswold Subaru in Hailey admit that Scoobies eat their front inside corners

)I wonder Mike as MY05 struts are similar with MY04 even if their suspensions are differents external why you change the springs, are they different shape/design?

I've already put my order in at my local dealer. They can't give me a delivery date, but I pester them every week and I reckon they are getting a bit pi**ed off now.
They just said that they will make sure they get the springs asap and they will book my car in for the next day, regardless of the work schedule just to get me off their back!
I have just put on the PFF7's in gold on my WR blue car with a Mongoose exhaust. The car now sounds as it should, but looks like its up in the air - the sooner the springs are on the better!!! I can't wait! Normally the germans are pretty good with their timing plans - I have to work with them so I know.... but its funny how they can change timing schedules when it suits them!!! Keep the pressure on and get those springs here!!!!!!!

Regards tyre pressures with PFF7s and Prodrive springs on new-age STI, I have an STI02 with Goodyear GSD3-F1s and find 33/31 psi F/R to be the best compromise.
Did try 36/34 psi but the ride was way too harsh even for me and was not pleasant at all + I don't imagine it does wheel bearings/suspension bushes much good either, turn-in and feel is slightly improved with the higher pressures but on a bumpy road it's too stiff. Am still on original shocks after 50000 miles so that may also be a factor in harsh ride, getting new shocks fitted soon.
Have Prodrive springs changed at all between STI02-STI04, would have thought not but springs may have changed for MY05?

As a Owner I can recomend Powerstation
Warranty should not be affected as long as they are fitted correctly if the Strut fails with a Prodrive sring fitted correctly by Qwick Sfit. no problems could arise. But if a Non Warrantyed part is fitted even by even a Dealer could have poiblems IMHOTony

Ok i have Eibach's on my Sti My03 and they are superb... the ride quality is much much better than the standard springs... I can't actualy believe they released the car in that way... the standard setup is crap.
now the ride is in another league, it wactulay feels much softer sprung than before when your just bimbling around, but really holds up much better under heavy load...
It now feels so much more planted, like the cars been made about a foot wider
it rides bang on now doesn't feel like your on a north sea ferry when hard cornering...
I really do push hard into corners and arn't a power only driver... Unlike some videos i seen on here so hopefully giving an honest appraisal...
If the prodrive springs are any different, that differnace would IMO be impossible to determine...
The Eibachs are supperb, if anyone states otherwise then they have no idea what there talking about...
I couldn't ask for the car to be set-up any better than it is at the moment... it really is that good... very very impressed and i'm mega fussy with setup...

Dazza if you hit a bump when cornering you'll see the difference the uprated bump-stops from Prodrive springs do (although the car lowers front about 2,3-2,5cm they give you back almost all the factory suspension travel which is critical when drive on uneven roads).
Of course no one says that Prodrives are the best springs around, just they are better than Eibachs and they have reasonable price - compared say with STI pink springs that supposedly are better!
You pay your money and take your choice.
