I'm looking for a pair of 21091GA190 springs. Although people list availability, when I order, the order is refunded with the part out of stock. I used a pair of cut down 1995 Ford Tempo springs for the front and they are perfect. Anybody using any alternates for the rear?

Yea, that part number is discontinued, and I did a search of dealer inventory, and none with 5000 miles of here in Northern MN, shows any inventory. It also looks like that number is for a 2WD car...

 

 

 

They are 2.5" ID springs, which happens to be the most common size for coilover springs. They can be had from many suppliers in many lengths/spring rates for fairly cheap.

 

I think, off the top of my head, that most EA82 rears are about 190 lb/in springs. I have definitely used 250 and 275 lb/in with good results. I think I'm running a 10" 250 Eibach in the rear of my XT6 right now (I'll try to remember to check later tonight when I'm working on it....if the stamping is still legible).

I did remember to check, and the stamp was still legible. 12" long, 250 lb/in springs, on KYB GR2s for a 4WD EA82 wagon, with stock upper mounts:

 

This gives a slightly taller ride height, and matches my stock WRX front springs very well.
