Wow I just went through all 81 pages. I've even inquired with some vendors.
07 Legacy Wagon GT
Goal: Near OEM ride height (+/- 0.5" of ride height forgiveness) while retaining a stiffer overall suspension setup.
From what I've read:
1. Go with H&R Sport springs with KyBs
2. Go with H&R Sport springs with Konis
If choosing 1 or 2, use a 3/8 or taller lift spacer for the rear. Using 1 or 2 leaves the option for using aftermarket anti-roll bars as well.
3. If baller status, go with Feal Coilovers with full suspension height available.
4. Go with Rallitek springs w/KYBs
If going 3 or 4, lift spacer not required, but aftermarket anti-roll bars are NOT recommended with the Rallitek springs.
All setups should allow for 18 x 8 wheels without fender rolling.
It took me A LOT of sorting just to find proper ride height photos.
