They fit on all. I’d be interested to see how much height you pick up on the R though. SDi told me 1.25” on the 35 Gen 3, but I think the 37pp’s pickup a bit more since they have some additional preload from the factory.

On top of the additional preload, the R has stiffer front springs, so I wonder what it’ll end up at?
Other way around -

35package will gain 1.75”,
37pp will gain 1.5”

R isnt really known since they actually have the heavier front end. I dont think its been really measured but im sure between 1.3-1.5”

Anyone with this set up tell me how do these ride? I just installed eibach kit and they run like dog shit. So f'ing stiff.
I have 23 37PP, installed SDI in front and eibach 1.5" about 3 weeks ago, it rides just like stock now. i would of liked it if it was 10% firmer.

Why stiffer, so you can ride like lowered civic with cut springs and have your struts top out the second they need any down travel?
No not that stiff but i like the ride quality of our sport mode setting. I was thinking with the eibach spring in the rear, it would be more like that without changing the mode to sport.

I'm debating between 1" eibach front springs or SDI tophat, and will be adding 37's. What will have less pre load, ride implications? I will being adding eibach rear springs to keep a rake (for light towing, H. Depot runs etc..)

SDI top hat is the way to go, do not do the Eibach springs. I’ve done both now and the SDI top hat is the way to go. My 23R was the test truck for Eibach so I got to experience all of the spring options and I recently installed the SDI top hats on my 24R and it’s a night and day difference.

Did you lift the rear as well?
