I had progress in my old car, loved the handling. I will probably get them on my WRX too, just not sure of what I am going to do yet. The shop I help out at, uses Progress on just about all the cars that come out of there.

Well I don't know the spring rates (but yes, North_Ursalia's site should have them), but I don't usually smile upon stiffer springs used with stock struts. Could be a bit squirrely.

Email the different companies and ask them what the spring rates are

I've been running Progress for about 5 months or so now. The ride is stiffer, but uncomfortably stiffer if that makes sense. The drop IMHO was perfect!!!

I have a set on my sedan and I am pretty happy with them so far. I called progress before I bought them to ask about the spring rates and stuff, they designed then for the factory struts since no one makes replacements yet. they will shorten strut life alot, but they seem to handle pretty decent, I wish they were stiffer though. the ride is pretty good for the ride hidth, but I was also on 500 lb. front and 600 lb. on a Civic before.

For me it's comfortbale enough. But who's to say my judgement is in lines of what you are thinking as comfortable. The ride is not bouncy I know that for sure...

I don't think Prodrive will tell you their spring rates... its apparently a secret. I do believe they are close to the rates on the Pink STI springs though.

The Prodrives will be on my car in the spring so I can't comment on them now, but I've heard only good things about them.

I looked into both of these as well as the sti pink springs, decided to go with H&R sport springs. I talked to the guys at subaru power.com and they all recommended these over any others if using the stock struts. I'll let you all know when I put them on in a month or so.

I have a set of Progress Group springs I'm about to install in my WRX wagon (17" BBS wheels). The springs were recommended by the Prestige Subaru guys (Asheville, NC performance-oriented shop).

Anyone have probs installing them? Anyone have scraping problems? I'm a little worried about my driveway hump and the wagon's "undercarriage". Some cars do scrape in my driveway, but my scraping would occur every day!

Everybody is going to have opinions on whats good, whats not, and until someone comes out with a comparison, no one will know. I personally will go with Progress if I decide to lower my car. We have had good luck with Progress products. We use them on our ITC Civic race car, that held a track record (recently lost it). Pretty much all the cars that come out of our shop have Progress products on them. They are good products.

it took me forever to install my springs, I think they welded some of the bolts together. I broke (2) 19mm 1/2" sockets, a 3/8 rachet, and pulled a muscle in my back. the rear seem to be alot harder to get apart than the front, I worked on the left rear for about an hour. you might want to get a torch to heat the bolts up, that seemed to help break them loose.

I have only scraped ounce since I installed mine over a month ago. it was on a pretty high speed bump and I have a TurboXS exhaust, which hangs pretty low. it just barely scraped the cat., and I mean barely.

The scrapes I have had (2 of them) were incurred towards the beginning stages of me installing the Progress springs. I came from driving an Xterra and then driving stock height on the WRX for a couple of months. It was a simple case of not going slow enough out of driveway-type situations. I haven't scraped since. You learn how fast you need to go and it should help you avoid any scrapes for the most part. Now some situations I'm sure there is just no avoidance dependning how low you car is and how the road/obstacle is, but for the most part you can avoid scraping by learning how slow you need to go

Wish me luck- my springs go on Sunday. If my driveway gives me too much trouble, I'll probably just sell my house.
