and please, if you guys go putting cages in your MSP, then:
-use the proper materials!!!!!! dont get a "pipe bender" from harbor freight and some schedule 40 plumbing pipe. in addition to being unbelievably heavy, the tensile strength is all wrong and the cage will likely shatter on a sharp impact. proper materials, in my opinion, means 4130 chrome-moly tubing.
-use the proper bender! make sure its a mandrel bender. jd-squared makes the best IMO.
www.jd2.com is their site. the model 3 is plenty for what we would need, and it is easily modifiable for use with an air-over-hydraulic ram if you're lazy or a wuss and cant pull the lever.. and get the degree wheel, youll need it.
-dont forget to tie into the firewall! dont forget to mount your seats on the cage! dont forget padding! and DONT COMPROMISE! make sure you triangulate, gusset where necessary, and make sure you know how to weld. no novice welding on your cage! as a rule of thumb, pretty welds=strong welds. i personally wouldnt use any process but GTAW (tig). go for the "stack of dimes" look and youll be fine..
sorry for the soap box

i come from the off-road world where this stuff is extraordinarily important. a crappy cage can make an accident worse for you than if you didnt have one.
anyone out there have a cage in their MSP? id love to see pix.
