Ive got a stock 99 DX coupe and ive been driving it for quite some time now. Been realizing how mushy the suspension is and how it tends to roll a lot...

Im debating which would make my car corner better and stay flatter through the corners. I dont care if the ride gets too uncomfortable, i just want this car to really do a better job at cornering.

So should i get a set of stiffer springs or some new front and rear sway bars? Im looking for a big improvement here so id like to know what would give me the better performance gain.

Nither.

Step 1 for you should be to buy a new set of dampers. Koni Yellows or Tokico Illuminas should do the trick for you.

after that, get your alignment optimized. AKA Non-OEM spec alignment.
