Just as the title says, I’m curious to know has anybody done this? I don’t mind the gap at the rear, also I do carry passengers in my vehicle, but I would like to close the gap up front. I have an IS300 awd and was looking at the Lexus springs, but didn’t know for sure if I could just install the front springs only. I know they’re sold in sets only, that’s not an issue. Has anybody done this? Are there any other ramifications by going this route? Any insight would be appreciated.

I have had a front pair of Downs for a couple months now, but am still waiting for a friend to install them. Several of us with 3xx AWDs have been either doing or considering the same thing -- different springs front-to-back. Look up Santorini, as he did Supers front and Downs rear (in fact, I have his fronts) and his front/rear gaps came up perfectly. Another did Halfs on the front and said there was minimal difference, and another seemed to get good results with Downs front only but he has also had an accident and replacement of his front end.
In short, we "think" that Downs-only on the front SHOULD even the car out, but because ride height isn't always the same we won't know until we try it. Indeed -- I measure mine occasionally and one time the right side fender height was the same front and rear(!). Another time, I could get two fingers on the right rear but barely one on the left rear.

Good to know, I’m just looking to get an inch to 1.5” out of the front, nothing too extravagant, but enough for me. I do appreciate the responses, so now I guess I can go ahead pick up some springs. 😃

If you're on instagram, ISFaster did this on his ISF with swift springs. Im sure he has a clublexus account. I was thinking of reaching out to him as I was thinking of doing the same thing. Obviously different vehicle, but its something.

I got the F sport 1" lowering springs for my 2014 IS250 RWD as a birthday gift from the wife. I wanted to close tire fender gape just like the rest. I installed the fronts and ran out of steam before I started on the rear, regular work kills/ rather work on my car.. After I got the front together I knew I would have some miles before everything settled and sat proper where it should after the 1" lower. So I thought I've got some time to get the rears on but as the front settled I loved the slope so the rear springs and spring puller are still in there box in the shop. They only down side I've had so far is I noticed some rear end fluid, small drops on the ground after the springs settled. My garage floor is painted so I noticed immediately. Very small amount, a few drops and usually only after the slip light yells at you a few times. As I panicked the rear end was going out. I investigated it I found a very small amount of fluid on the passenger side rear end mount and bushing. I cleaned this up, wiped everything else in the area down as I couldn't figure out how it had got there. Checked the rear end throughly for cracks leaks worn gaskets, loose bolt-nothing. Puzzled I figured I'd give it a day or two and check to see if there was fluid in this area again, sure enough a very small amount. With the front lower the angle of the rear end changed causing some excess fluid to run out the breather/over full tube at the top of the rear end case. I cleaned everything up one more good time and checked the rear fluid and it quit and I haven't had a drop since. I imagine when I flush and change rear end fluid to Motul same as my brake fluid it will happen again until it levels it's self off. I'll post some pic of the car and area where I found the fluid some time later today; I take pictures of the car like a girl does her pet.

I didn't record when I measured ride height last but I got a full inch, and the rear hasn't got done yet I like it, the front clip does not. Regular Areas you drive where you didn't scrub before you will now. I got it recorded as Oct 02 2018 at 66,348 so i've got right at 10 months - 10k miles on them. I really didn't notice a difference until I did my first oil change after install. I use Cusco's tire slopes in oil change routine and I couldn't get myself under the front end of the car any longer I had to really reach for it. Oh also a recent realization I didn't adjust headlights so I can ride with the brights on all the time, like a true road warrior.

this was all I got, I have a nice curve to a left 90 off interstate with a tight curve right and and tight curve left down a hill so my slip light is pretty active. I haven't had any other issues or drips.
