Should I reinforce my rear strut towers? Options

[chad newton]

My plans for my 914 are to run as a track car more then on the street. If I wanted one for the street I probably would get another that at least had interior and paint. I will be installing a cage, already have the 911 front suspension, will have the sway bar installed shortly, around 250hp 2.7, what else needs to be looked at? I have seen a lot of guys running a bar welded to the rear strut towers and was thinking about doing that to mine. I will not at this time connect it to a cage because I was thinking of starting with a six point then maybe later going all out. Isn't it a good idea to stiffen the rear towers before I tweak them out? I tried the search engine but again I couldn't find any threads pertaining to this perticular mod.
