I'm lost as to what you think this tensional improvement a brace is going to make that the reinforced bulkhead in front of the battery that ties both strut towers together is not already. THis is particularly true if you imagine it as a massive U section made by the front bulkhead, the horizontal plane over the tank and the secondary bulkhead in front of the dash. Even that U section has a braced top made by the substantial steel braces producing an effective box section. Interestingly I would have said that the front structure is considerably stronger than the rear and I would not concern myself about either. My SpecBox has neither front or rear ties (because we are not allowed too) and I do not consider it to lack any structural rigidity.
Having said that, if it would make you feel better it certainly can't make it worse. I simply see it as a waste.
