I added Whiteline sway bars this last weekend. I got a 24mm extra heavy duty blade adjustable for the front and a 22mm heavy duty triple adjustable rear with bracket braces from Sean at Vigilant Motorsports. (Factory is 21mm/16mm)
These made the car a LOT more neutral. This is the way the car should have come from the factory! I’ve got the front set on the softest of the two settings, the rear on the softest of the three settings. (I may bring the rear into the middle hole after i’ve gotten a chance to autocross it a bit and see how it reacts)…
Additionally, I added the Energy suspension diff crossmember inserts, diff inserts, and tranny crossmember inserts, along with a subaru “Group-N” tranny mount. There’s a slight bit more vibration, but a LOT more settled/less floppy driveline!
