i have a 99 civic LX.

installing a subframe from an integra ls.

want to use my civic si front sway bar.

possible?

 

All 88-00 Civic and 94-01 Integra sway-bar may be swapped in as long as you get the associated end-links, bushings and D-brackets. If your car did not originally come with a sway bar you have to swap in the LCA's from a sway bar equipped 88-00 Civic or 94-01 Integra

 

You would need your SI lower control arms/si forks

 

Ok thanks a lot

Wasn't sure if the subframe was the same is all.

 

You'll need more than that. The subframes are not the same. I responded to your PM but thought I would drop this here for anyone else interested:

Save your time and money and opt to go with a smaller (than 26mm) front sway bar for minimized understeer. The only reason I did it was to save the weight on the LCAs which was 4lb on each side. Other than that there are plenty of options for DC2 applications to go larger or smaller.
