Yes, I'd like to do this but there have been rumblings about changing the brake rules in Street Touring to mandate that stock weight rotors be used. It would be just my luck to spend $800 on 2-piece rotors and have them take-back this rules allowance (they are known for doing that). I have never heard of affordable 14" rotors for the Mustang... got a link? Girodisc is $800 a pair.
The stock 14" Brembo rotors are a staggering 25.4 pounds each!

Yep, not allowed in SCCA ST.

I'd love to do a 1-piece driveshaft, in aluminum or carbon. Again - not ST legal.

Already installed. Gallery:

With the rule set I'm working with I'm pretty limited on further weight loss. This is also a daily driven street car, so pulling all of the insulation and such would not be as streetable. But I like the suggestions! I'm still looking for pounds... the 2-piece rotor thing is going to happen soon, one way or another.

Zero issues in the past year of street driving, autocrossing and tracking the Mustang. Amy drives it to work every single day.
If you go back in this thread to post #92, I describe who's battery mount we used, and the other bracket and bits we fabricated to make it bolt into the Mustang without having to drill any holes.
I have PC680 Odysseys in 3 of my personal cars. Only car I have any issues with is one of my BMWs, which has a known battery draw when parked - and draws down the battery after about 5 days of non-use (no matter the battery). We keep it on a Battery Tender and its fine. One of these days we'll chase down the voltage leak...
Thanks,
