I have no intention of doing this anytime soon but i was just wondering has anyone here removed there back seats and added a roll cage? how much does it cost after installation and removal of seats? Also is there a significant change in handling/acceleration? Finally is the car much more stiff/uncomfortable for a daily driver?

 

I did this years ago to my 06. Removal of seats and belts was simple. Mine is an AutoPower bolt on and it works fine for the racing that I do. Its not a full cage but I can tell you that I didnt really notice any difference in handling. Cant quote a price because I did many other things at the same time. Here is a pic if it works. Not really sure how to post them anymore.

 

I cant comment on the roll cage but removing the seats takes like 5 minutes.
The bottom is held in with little tabs so it just pops out. The backs have maybe 4 bolts that hold the hinges in place. Very simple to remove yourself.
