Is it possible to install the rl 4 pot calipers onto the dc2 integra?

 

Yeah it's possible. Info is out there, not worth it imo though. Would rather do the ITR upgrade or Wilwoods.

 

People have done it before, but adapter brackets are difficult to find and expensive.

You also mess up the brake balance, the front/rear piston size and proportioning valve were designed with a certain bias in mind, if you start changing the surface area of the brake pistons then you change the braking bias. Without recalibrating you will likely see reduced brake performance.
