Lowered Suspension Owners: Are Rear Toe Links Necessary?

[BodegaBay]

Hey all,

I saw a YouTube video where the installation shop installed H&R springs on a Model 3 LR RWD and also aftermarket (SPL Parts) rear toe links. They noted that the factory toe links do not provide enough adjustments post lowering. Is this correct?

I have a 2019 Model 3 Performance (full pkg) with 15/20mm spacers and intending to lower with H&R springs or MPP coils.

It definitely provides the flexibility needed for any adjustments. I recently installed MPP Sport Coilovers with both rear toe and camber and didn’t need to do too many adjustments when I had the car alignment done. You may want to add some
Camber for a track day. I Couldn’t tell you if adjustments would have Been possible without them running a stock setup.

Thanks for the feedback @Xerious I'm strictly street use and zero track so no additional camber links needed.

My understanding is that with the MPP coilovers, we need the camber arm to allow for even tire wire. However, we do not need the aftermarket toe

It also depends on how low you want to set the ride height. When I first set it to the maximum lowest setting it was to see how low it would actually get. It was a one finger gap but after a few days of driving and settling it went to zero gap. I've attached a photo of the zero gap and then one finger gap. I raised it about one finger from fully max low position on the coilovers. You can see the difference in the photos attached.

When people say you "need" the adjustability, they mean that you need it in order to restore stock alignment. Not having stock alignment isn't the end of the world (depending on the severity, obviously) and normally the "price" of having poor alignment is abnormal tire wear.

You really don't need the arms, but you might see uneven tire wear if you lower the car substantially and can't restore alignment close to stock.

Understood. Thx for the input.

What's your SV104 offset and width and tire setup?

What's your SV104 offset and width and tire setup?

19x9.5” +35

 

[Murattukaalai]

19x9.5” +35

What's the color of the wheel and size of tires? Last question I promise
Thanks

Would you say the camber is much more of a necessity than the toe?

 

[MountainPass]

The stock toe adjusters are capable of aligning the car properly, they just aren't as accurate as a quality set of adjustable arms. Upgraded bushings in our arms are a bonus as well. The rear camber isn't adjustable at all, so when lowering the car that is the next thing you will want to look at.

Having a lot of toe will absolutely wreck your tires. A little camber does wear tires a but it's really not much at all (and it obviously massively improves the handling).

^absolutely, camber that's off, you can still use many many miles (known some folks with over -2.5 front cambers, slammed cars as daily driver, tires still last thousands of miles), toe's that's off, it'll eat up the tires unevenly right away

but the stock toe for the model 3 does not really need to be upgraded apparently, its the camber that does

No worries. The wheels are Signature SV104 in Brushed Black Tint wrapped in Toyo 265/35s @SignatureWheel is running a big Black Friday sale right now. There's a thread on here with more info.

Yes I ordered one and thinking of triple black tint vs brushed black tint

@Xerious,

Do you have a front quartering shot?

Ski

I got a way with just doing the Camber arms. However, front is out of spec, but no solution for that quite yet.

What do you mean by out of spec? Not aligned properly?
