One of the first mods I did to my old 2000 GT was a pair of Kenny Brown "double cross" subframe connectors, and I credit them with keeping the car nearly rattle-free for nearly 180,000 miles, not to mention the huge improvement in how it drove on bumpy roads (felt like I installed new springs!). For my new 5.0, I did some searching around online but have no clear conclusion for whether they make sense for me based on how I will use this car. This car will spend about 75-80% of its life on the Interstate. I don't race and I don't drive like James Bond (well, not usually). But I will be driving this car for the next decade or more and the miles will add up eventually. What is your opinion - will they do the same for a new 5.0, holding it together for the long haul, or should I spend my mod money elsewhere? Based on what I am reading, I am leaning away from subframes, but if there's as good a reason to install them on a DD S-197 as there was on the Fox/SN-95 platform, I'll do it. Thanks for your help!
