Default LCA/Toe arms 2018 STI

Hello everyone. After searching extensively, I haven't been able to find my answer.

I currently have a 2018 STI that is lowered on swift spec r springs. I got it aligned, and rear camber is -2.1, they got toe to 0, and I had front camber set at -1.5. I am fixing to order HKS Hipermax coilovers, and I'm looking into rear LCA's. My question is: do I need rear toe arms? I know when the LCA sucks the bottom of the wheel inwards to reduce camber, that will increase toe. Is there enough adjustment in the factory setup to get the rear toe to 0, with ~-1 deg camber?

This is my wife's daily driver. It will see no legit track time, just some canyons on the weekend.

I'm looking at doing the superpro LCA, in case that makes a difference.

Thanks for the help!

Hey!

I have a 2016 WRX that has RCE yellows. I originally had just SPC lower control arms. I then upgraded to SPL lower control arms and SPL toe arms. The shop I align at (West End Alignment in LA) states it makes it much easier, also they stated that the bolt LCAs like the SPC arent the best, they work but arent too great. I dont think you need toe arms to be honest, I just wanted a perfect alignment. You should be fine with superpros

Thanks for the info! I did the LCA's and toe arms on my wife's Forester XT when I put coilovers on. But, I dropped that thing like 2.5". The STI is only around 1" so hopefully I'll be good to go. Thanks again!

you will need toe arms if you're lowered and reducing camber lower than factory spec and trying to get zero toe. for example my WRX is on RCE yellows and I have -1.4 degrees of camber. the toe adjusting cam bolt is maxed out and that results in around 0.1 degrees of toe in. if you leave camber at -2 you will have enough adjustment to get zero toe.

That's exactly what I needed to know! Most of the discussion I see is around the control arms, not much around the limit of the stock adjustment cam on the toe arm. I'll go ahead and order both, just to make sure I have more than enough wiggle room. Thanks!

I think the SuperPro lcas might come with a cam bolt for the toe arm to give you extra range on those too. I recall one of the stamped lcas does.

Why the hipermax or coils at all for a daily? Those are gonna be a bit rough. If you're married to the idea of coils custom feal or fortune with more daily oriented rates would probably make you happier

Superpro sells a "kit" that includes their toe arms for a really good price. The whitelines have an eccentric type bolt/cam on both ends of the LCA, I believe that helps with obtaining the needed toe adjustment. I just remeber those were a nightmare on the FXT to get setup good enough to break in the suspension pre-alignment.

I ordered the Hipermax GT coils. They are a daily driver valve/spring rate config. They are supposed to be one of the best setups for a daily car. The Hipermax SP is the more aggressive, track type setup. I have heard some good things about the Feal coils with custom rates, but I couldnt pass up the deal I got on the HKS setup.

The car is currently lowered on the Swift springs, and to be honest, the ride isn't that great. It is almost as rough as my last set of BC BR extreme low coils. The car handles great, but the ride is too much for my wife.
