Springs are sold. Rear tophats are still available ($35)
Price Drop! $100, local.
I bought them from Oakos over 2 years ago, had them professionaly installed, and put about 40K miles on the car while running them. Selling because I upgraded to stiffer Crucial Racing Springs recently.
They're in good shape. The rubber on the bottom coils still looks good. They are stiffer and lower than stock so they made a world of difference, but they're progressive so they're comfortable for daily driving.
Here's a link to them on Oakos (although I think they were closer to $300 when I bought them).
These are the wagon specific version, but that just means the rear springs have a slightly stiffer spring rate, which IMHO, is a good thing for a sedan too. They're for MY 02-03.
