I have a 95 Impreza wagon with prodrive p1 springs. The performance is alright, but I suspect it may be limited by not-wagon-specific rear springs. The rear is slightly lower than the front, and bottoms out occasionally on really hard turns, when I'm pushing it really hard and there are big dips / bumps. (This might be just the tire rubbing, i cant really tell)

I really enjoy the prodrive springs, but I worry that the rear springs may be affecting my handling in a bad way. I.e. excessive understeer... Are there any springs close to the prodrive rates, but meant for the wagon? I like the even-ness of the above car. Is there somewhere I could buy just the rear springs, or maybe a cheap ground control setup?

Also, I have gr2's, so I'd like something that won't tear my shocks up by being too low or too stiff. I.E. 15-25% stiffer than stock. Please do not suggest any tein products, or coilovers, because I am on a tight budget. Thanks
