I have a 2004 LS430 and I’m getting ready to install the rs-r super downs on some KYB excel-g struts but I’m afraid it might be too low and end up rubbing too much and ruining my ride. I currently have 20” wheels 245/35/20 in the front with 5mm spacers pretty flush with the fender and 255/35/20 in the rear. Do you have any experience with super downs? Any pictures and/or feedback is much appreciated it. As it stands I have about 1.75” clearance in the front and 1.5” in the rear (wheel to top of fender)

Cant help with the rsrs, but any reason you decided against coilovers in favor of the springs?

So few people here actually use lowering springs because of the other, better options available. Plus, there aren't any good aftermarket struts to really dial in a lowering spring. You can get good coilovers and have more adjust-ability and really dial in the ride quality or go with air if you want to really slam it but still have a functional car where you do worry about scrapes.

I thought about getting the Tein flex z’s initially but than I decided on some lowering springs. I had ordered the Tanabe Nf210 but they are discontinued. I’m not looking to mess around with the car’s height at all. Just looking for a clean static look (not slam it!) and I felt that the rs-r super downs were the right fit along with the KYB excel-g struts

Coilovers would allow you to adjust your height from around stock all the way to slammed. Most who have them don't adjust them constantly, just dial in the exact height you want based on your preferences, current wheels, etc., and then leave it.
A few years later get some new wheels with different specs? No worries, adjust the coilovers again, and youre good.
with springs, you're stuck with what you have in terms of height so if you put these on and they don't work as you would like with your current wheels, that would not be great. In my opinion, if you go with springs, it would be drop first to see what you're working with, then wheels that would work with your non adjustable drop.
I'm guessing your springs were maybe $250-$300, and struts maybe $450-$500? So $700-$800 total, but for maybe $150 more you could get a set of bc coilovers with your choice of spring rate, already assembled so you never have to even touch a spring compressor!

Yes, you are right. I paid about 750 for both springs and struts. I had purchased the Tanabe NF210 but they were discontinued. I then started looking at the Tein Flex Z which would of cost me roughly the same I paid for both the springs and struts. Do you recommend going with the Tein coilovers instead of the lowering springs?

I can't speak to the teiin coilovers, I don't have any experience with them, but I'm sure they're good.
I went with bc coilovers, and I absolutely love them.. the ride is smooth and the build quality on them was solid. You can also adjust the firmness of the shock if needed
