dude, you get the same noise with the eibachs. Thats why i just put my car back to stock height. I'll just wait for something else to be released. Besides, I personally think the Lancer handels better stock height w/ 17s and with the RRM K-bar.

 

im gonna bump this because a lot of people still dont know about it. (including me). i called progress and they will have some insulation sent to me within 2 days. so ill check it out, but my noise it SOOOOO Loud and obnoxious i hope this little thing will help.
