EA81T front springs ... vs EA82T RX front springs?
Posted 08 February 2007 - 02:37 AM
The infamous Subaru Suspension Chart does not cover the EA81 at all.
Does anyone have specs for the EA81T-style front springs?
And I know that the front of the EA81T sits lower in front.. is this a function of the strut height or spring height or both?
Posted 08 February 2007 - 08:20 AM
Stabilizer Bar: 22mm
Coil Diameter: 130mm
Spring Coefficient: 25.5 N/m
Outer Cylinder Length: 376mm
Piston Rod Diameter: 20mm
- Expansion: 785 N
- Compression: 490 N
The rear is completely different, so comparing it is moot.
As for the height, the Turbo and non-Turbo share the same struts. The springs are different, but if anything the Turbo spring makes the car sit higher. It has more coils and is stiffer. I personally do not notice a difference between the two in ride height in the front though.

My coupe squats in the front but the back is high, it may have had its torsion bars adjusted.. and if the springs *are* shorter, that's what spacers are for.

As for the RX springs, they will lift the front of your car an inch or two because their free length is 13-14 inches.

4WD RX Sedan (EA82T)
Front Spring Coil Spring Coefficient = 27.5 N/mm
and from the FSM
Front Spring Coefficient: 25.5 N/m
So the EA82 RX springs are a little more aggressive than the EA81T's. Not so much that I'd seek them out.
The EA81T front struts/springs sit a little lower but not enough to account for my coupe's stance, which means it's more likely that the back was clocked up a little. Not that I mind, but if I were to equalize the height and then decided to push the front up a little more, I'd probably go with 4WD front struts and perhaps add spacers under the springs.
Thanks for helping me hash this out, guys. This weekend I'll have to take some shots of my coupe so i can finally show it off! Then you can see what I'm talking about too.

No idea if that was a factory option, or if it were an aftermarket thing....
