I have an evo ix mr with the bilstein suspension. Is it possible to lower my car with these rather than buying other shocks.

 

lowering springs, swift makes a good set for your suspension.

 

yes, has been covered many times

swift is a good option.

gtworx

gtworx springs will drop the least 20mm front 15mm rear.

The shocks will handle these springs fine because these springs were designed with the stock shocks in mind.

Other springs you'll have to do your research, but most people aggree that tein s-techs are bad because they lower too much without enough rate.

I've got gtworx springs and am waiting for the bilstein hd to be back in stock.

Any of those three will be a good choice for handling. Other springs might work as well, just do the research.
