86 is not a race car. It is a fun car that can be raced.

That's about a 18 - 20 lbs savings in unsprung weight, with more tire (estimated because I have no idea how much weight the wider tire will add). In contrast, a carbon driveshaft seems to save about 10 lbs. If you wait until your tires need replaced anyway, the wheels will likely be less expensive as well.
Or this. If I could lay off the junk food all over the place at work, and go hiking more, I could probably drop 30 or so pounds of driver myself. If it mattered.
Also tempted to make that last part a sig.

Well, I'm not trying to make a race car, just looking for simple changes. But if the drive shaft isn't worth it then I'll stick with the exhaust and tune. I already have wheels and tires, and they're far from the lightest option, but they're still no heavier than the stock setup.

I guess I shouldn't have gotten 245/40 MPSS then...
