Cornering loads are spread more evenly across the tires delivering more grip and, frankly, that’s what it’s all about. You also get improved tire wear as your tires stay flatter and more upright. Comfort improves because your car sits flatter through bends meaning less movement inside the vehicle.

Wow. Should have done this sooner.

Just added these to button up the suspension. I waited because I figured STI sway bars were already pretty beefy. Dropped it down on IAG Street Series coil overs, Cobb lower control arms, and got the height/alignment dialed in where I wanted it. While it was miles better than stock, it still had a bit of understeer and body roll. I took advantage of the sale and picked up both front and rear sway bars with end links and rear braces. It’s a bit of a paint to install but holy smokes what a difference! Flat cornering makes all of the other mods sing in harmony. I hope to get some auto cross in this spring to try it out on a course. Not sure where the limit is anymore and I don’t want to find it on a mountain road. My advice to tuners would be to start with the sway bars and add on from there.

Undeniable worth it

I have all spl suspension control arms that I have just recently installed. When I bought this, I never considered its ability to work well with other aftermarket components, however after just installing the back sway bar today. I noticed that the end link bolts that go through the end links did not have any length to thread the nut onto the bolt after I slid them through with both washers on either side as per the directions. Now, This is an easy fix I can go to my nearest home depot and take a bolt in to get one that's just a bit longer. This isn't a big issue, but with the amount of money, I have spent on this and the fact that it too is an aftermarket part and it too should able to work with anything you attach it to. I would at least expect bolts to work on all different types of aftermarket parts. As for the performance. I can't deny that it isn't worth it. It most definitely is, some words of wisdom I would give to you would be if you have an aftermarket control/camber arm. Just be ready to go and get longer hardware so you can do it properly. For right now, I have installed the bolts with no washers, but I do not intend to leave them like that for long. All in all, if you want your Subie on rails I would definitely buy one of these if you have the bag for it. As well as all the SPL stuff that is on the website. All of the components are extremely adjustable and are really needed if you really want your spaceship's suspension to be on point, and I would go with the eccentric lock option for the toe arms.

Connor,
