Adjustable Rear Control Arms

[Radlaw]

Received email ad for Adjustable Rear Control Arms for Model 3. EV Tuning Model 3 Control Arms. What are they and what do they do? I understand coil over kits for lowering the car. Do these do the same?

I don't believe adjustable arms are needed for the Model 3 because once you start changing the length of the suspension components you can cause more harm than good. Where these would be beneficial is the bushings appear to be sealed and therefore will have less deflection under hard cornering and will increase stability. SPL & Mountain Pass Performance make good sets too.

Thanks for that information. But it doesn't really tell me what they do.

These do not lower your ride height. They reduce suspension movement in the rear, slight weight reduction and improved durability over OEM parts. You only need these if you are aggressively tracking your car.

Got it. Thanks for info. I'll hang on to what i got.

This allows you to adjust the alignment. I think factory only allow toe adjustments. This will allow you to adjust camber that is needed after installing lowering springs.

The price is still so high though.

Thanks for the info. Is that consistent to what TexasTeslaRacing said above? Love that both of you are from Dallas.

Kind of. These allow more adjustments and possible go more negative camber for track. I'm more interested in it to get a more neutral camber. I'm getting inside tire wear after lowering my car. There is no way to adjust camber without using aftermarket parts. I haven't seen camber adjustment for the front though.

I think it's crazy how expensive these are. It's basically just a rod that you can shorten and lengthen. I guess it's paying for the R&D.

We may be talking about two different types of control arms. A rear control arm, as radlaw asked about is not used to adjust the rear camber. You would use a rear camber arm for that. I answered his question referring to rear control arms, which you should not adjust even if you lower your vehicle. If you need to adjust camber, only do so using the camber arms. The rear camber arms are very different and they do come in handy after you lower the vehicle to get the right amount of negative camber in the rear. The rear camber is not adjustable with factory camber arms.

Yup. Camber and toe arms are what you need.
