Which springs
Ok I've got a 2005 blob wagon and it's time to fill the arches ,so what springs are best for a wagon that still leaves plenty of ground Clearence for our nations obsession for speed bumps and still retaining a comfy ride .

Actually no, Prodrive springs are not the same as Eibach springs... they may both be made by Eibach but the spring designs are different between two.

correct they are different as subaru had them made to how they wanted them, i also have a set of blue prodrive springs and must say they are good lowers the car nicely and the ride quality is the same if not better than standard imo.

I fitted prodrive springs to my blob wrx about 2 months ago and they have made a massive difference to the handling of the car. Doesn't so much of a boat now when turning in for corners

For goodness sake remember to change the BUMP STOPS though! An STi for example is touching the start of the front bump stop at 17mm of compression from standard. If you want to lower it 30mm then get a really weak spring or just take the spring out- because it'll just sit on the bump stop anyway!
O.E. STi bumps are 60mm long and compress 13mm with 90kg on them then not a lot more after that as they are a steep rising rate.
Rears are 80mm long and I can crush them 30mm with 90kg on. Clearly more progressive in rate and it takes 45mm to get to the start of them.
I know the Prodrive springs either came with or had Bump stops specced for them.

The Prodrive springs have a different compression/damping rate to the Eibach springs plus they have more anti-clatter wrap as well, so you were correct in as much as they were manufactured by Eibach but they are definitely not the same springs. 
And Tony is never wrong he just learns from his inaccuracies.
To the OP:
Some dealers are still selling the Prodrive springs plus some new sets do come up on eBay.
. Plus make sure you get someone to do the job who can properly and setup the steering/suspension with the Prodrive settings properly.

in the same sentence you will also see that I put my spec c springs are eibach also And the chances are of getting any replacement springs for a blob (prodrive eibach's) are virtually zero, so your stuck with just eibachs then

Well that didn't take long to get a bite, are you sure you're not JackClark in disguise?
There are some sets of Prodrive lowering springs for sale at the moment albeit for newage STi's and the seller is a Subaru dealer.

@OP eBay is a good bet if you really want the a Prodrive ones (I got mine from a Subaru dealer on eBay) but the Eibach branded Eibach springs are just as good from what I hear.
