Re: To go STU or not (2006 Mustang GT)
Wow, that's way lighter than I thought these cars were. Good start!
Yea, the Yokohamas are heavy, and CCWs in that size aren't super light, but that's lighter than cast 18x10s made for Mustangs, by a lot.
Factory batteries tend to be 35-50 pounds. The lightweight ones we always use (Deka, Odyssey) are 14-18 pound AGM style. So figure 20 pound savings, at least.
Most stock seats I've weighed were in the 45-80 pound range. The heavier end of that scale was a very pimpy power BMW sport seat, and the lighter end of that were cheapie manual 1980s era E30 seats. Yours are probably in the 50-60 pound range, each.
We usually see a 10-20 pound drop going to coilovers from OEM struts/springs.
The stock manifolds are HEAVY cast iron lumps. You could lose 50# easily, and even more if you made a dedicated lightweight exhaust. Full lengths would be the smart move, if you're going to bother with headers... more power everywhere.
No, this is even better base numbers than I expected. Since your car is already under 3400 pounds in FStock, its only going to get better in STU trim.
I think the Mustang might give the RWD STU cars a run for their money. And hell, with Nats moving to Concrete, the AWD advantage might be diminished greatly... your car can use a kickass Torsen that costs a small fraction of a "real diff" for a BMW, much less a AWD car. That is the key - getting a good diff and maximizing the grip from the 285 tires.
