its not that hard, impact wrench and air compressor makes it go much faster. I’ve done several cars in the past.

Where did you buy the spacers from? I might go with this

I have a 2018 350 AWD F-Sport, are these the springs I have installed already? I'm looking for a very mild drop with little to no decrease in ride quality.

No, the F Sport Springs are blue and no IS comes with them stock unless the dealership threw them in as part of the deal you made with them but you would have had to push for it as they wouldn’t do it just cause.

Ah, thank you sir. Do you know the exact drop the blues give over the stock F-sport springs, and their spring rate difference off hand?

It’s about 1 inch all around. Not sure about the spring rate.

We recommend getting some quality H&R spacers so your wheels don't fall off when driving lol.

The spacers I grabbed of Amazon were really good quality, Checked after 50 miles and after 500 miles and the bolts are still torqued to spec!

I had super downs installed for bout 2-3 weeks. Great drop, rear was just bit too low imo and ride quality was poor-fair. Was able to get Downs rears , installed those in rear. Gave car imo perfect drop. Front could be lower by maybe .5” but amazing drop nonetheless and the car legit feels like stock ride, just changing the rear springs was night and day difference. Maybe a tad stiffer but def daily drivable 100%. Will take pics tmrw.

Is there a key somewhere I'm missing that shows the exact differences between OEM and these three spring (down, super down, OEM F Sport) drops and rates?? I mean, they have been out for a while now, you'd think someone has made such a key.

Anyone know the stock ride height in mm and exactly where it's measured from?

I can do that, but that's going to be inaccurate every time because of bodywork differences. There should be designated places under the car where the measurements are taken properly.

You have super down in front and regular down in rear? or just a rear drop?
