Default Suspension for a 300whp build?

Hey guys, new guy checking in with little to no knowledge on this platform. Just full sending like an idiot.
anywho, I want to have my suspension set up properly for a 300whp 1996 civic hatch build. My personal preference is a stiff ride, not sure why but it makes me feel planted to the road! what would you guys recommend I upgrade? Budget isn't much of a concern for me, I'm honestly not sure what would be good to upgrade and what would be a waste of money.

Sorry if the post sounds confusing, I'm just as confused as you are...

Koni Yellows dampers w/ Ground Control Coilover sleeves ( 450F/350R spring rates)

Progress CS-II coilovers with same spring rates above

Yonaka --- GARBAGE

Function+Form --- same GARBAGE

Noted, thank you. how about sway bars and what not? The purpose of the build is just to be a DD but I feel comfort in knowing I can depend on my suspension when I send it. Like I'm not sure if things like camber plates would be necessary, that's where I get confused

New OEM bushings, maybe ctr sway bars with subframe brace (to prevent tear out),

also consider brake upgrades, you will want to stop that 300hp hatch.

my old setip was AMR 650F/550R with Hyperco Springs, was really planted! Swift also is a top tier spring.

Fortune Auto, Ohlins, Bilstein are a couple other options.



edit:the lower you go the more necessary camber arms become.

Most definitely will be upgrading the brakes, and going with some 225 sport cup 2s.
OEM over aftermarket bushings?

Unless spherical bushings, yes OEM over aftermarket. My hardrace oe style bushings hardly lasted two years.

Good to know, anywhere I can buy the OEM bushings?
this might sound dumb but, how many pieces are in the suspension? I'm trying to get an idea of just what to upgrade

I live in La Mesa, might be worth the drive to check things out, thanks for the heads up!

I assume you did, Biggie, but did you tighten your bushing bolts with suspension at ride height?

The front lower control arms failed first, the bushings connected to the subframe. The shock bushing was starting to separate too. I still have the compliance bushings in, they seems okay, but I’ll likely swap them soon. The rear lcas held up better, when i pulled them the bushings seems intact, a friend was goimg to try them ,but he wrecked the car so never got to keep pushing them.

and yes, suspension was fully loaded when torqued.
