I took my tanabe springs off and switched them to swift springs. After installing the swift springs I noticed a big difference from the rear driver side to the rear passenger side. The passenger side sits almost a finger higher. Do lowering springs have to settle or is this how it’s gonna be. I’m totally not happy with how it looks it almost looks like stock smh. Here are some pics. Please help... my car is a 2013 gs 350 RWD.

They do need time to settle over a few weeks but even then the initial drop should be even on both sides. You either have something else wrong in the suspension or they didn't do a proper install by preloading the suspension before tightening everything down (most likely reason for uneven drop).

I did it myself. Maybe I did something wrong but I had tanabe springs on before this so it was already lowered and the tanabe looked good

That looks like the wheel gap on a Ford F-150 4x4! I'm guessing you tightened everything up without the weight of the car loading the suspension.

I'd redo it and make sure you don't torque anything until you've got the natural weight of the vehicle on the suspension

Lift the car up and inspect both sides. Make sure that both springs are sitting properly. Also, check if one side was installed upside down. This may or may not cause an uneven drop.

Lexus factory springs used to come color coded (not sure if they still do that) to identify left from right, and their lengths were slightly different to accommodate the uneven road surface (most roads are built with a slight gradient to allow for water runoff, etc.)

See here: https://en.m.wikipedia.org/wiki/Drainage_gradient

If these replacement springs were “built properly,” then the uneven height would make sense, even though it does not give you the “look” you want.

Form follows function, and all that...

Might be an install error. Never had this issue before.

With some cars the spring can be rotated where it doesn't seat properly in the lower spring perch. This naturally raises the body on that side by the distance the spring lacks from being properly seated in the perch.

I rotated them yesterday and still nothing changed. I’m about to take them out and switch side to see if it does it to the other side.

Looks like you raised the car. Has to be improper install, unless you got the wrong springs.

What was the reason for the switch?

I didn’t like how the tanabe lowered my car. I’m on 20s and originally just wanted to close the gap from the stock look but after the tanabe springs broke in the car looked like a lowered car something I didn’t want just close the gap. So I did research and heard the swift springs would be the best bet. It’s actually starting to lower from where it was just needed to drive the car a bit. Also swift springs feel a lot more comfortable also. I’m not saying tanabe is a bad spring just not what I wanted.

I had the same issue. I dropped on Tanabe (and for those reading comments about them not being good, or bouncy, or ruining shocks, ya'll are crazy and are just looking for bologna to complain about), and my rear right was a half inch higher. After about 100 miles, I knew it wasn't about settling. So I got it on ramps and loosened that big *** bolt at the hinge point of the rear control arm and let it sit for a few minutes before tightening up again. Even Steven now.

Thanks bro so far it has went down a little I’m driving from the Bay Area to Oklahoma tomorrow so I’m sure that should really get them settled in but it’s definitely looking a lot better. Before I leave I’m gonna try what you did and put it on a ramp.
