Requirements For Lowering - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Alpha86 · 02-02-2019, 12:47 AM

It appears this hasn't been entirely discussed (or at least not in its own thread), but what is needed to maximize reliability when lowering? Going with the Eibach Pro-Kit (1-inch drop all around) and planning on adjustable LCAs, rear toe kit and front camber bolts. I hear lots of people damaging their swaybar end links with coilovers, does this need to be addressed as well? TIA.

Front endlinks to match drop.

Lowering can cause issues with the oem links both at the upper and lower joints.

This info is in this forum, more searching needed.

I think a lot of it depends on how low and what your objective are. I'm on some tein flex z. They seem super low to me. All I have are lcas. Maybe I could do better but I don't run into any issues on the street.

If your worried about endlinks, get adjustable ones.

If it is just 1 inch lowering with Eibach Pro, you don't need anything other than replacing the springs and an alignment after that.

But I would replace the shocks and struts together with the springs since your car is 2013.

When I installed Prokit springs 65k miles ago, I wished I had also installed a Roll center bumpsteer kit. I now have the whiteline kit. The difference in feel is noticable. A nice "planted" feel. I would suggest it with the parts you have.

I have the same. Zero bumpsteer.

Eibach pro is the same drop as the trd springs they are a factory option and warrantied even as a dealer installed option. If Toyota doesn't even recommend anything other than an alignment, then its safe to say anything more would be unnecessary and likely a waste of money.

Who decided a roll center kit was not great to install with drop springs?

Is it truly a "roll center" change? Most modern suspension design theory, has pushed static roll centers down the list of concerns.

Can't say with certainty, but likely Tetsuya Tada; the chief engineer for the 86 at Toyota. Could have been one of the TRD engineers though too, but I doubt he was not at least consulted.

Mac strut needs the kit to fix the suspension geometry from lowering. Believe whatever you want though.

The kit is a huge improvement in feel. But don't take my word for it.

You could skip the rear toe arms. The stock eccentric toe bolt in the rear should be able to keep you in spec with your mild drop.
