The theory sounds good until you do the math. I just did a quick check on TireRack of 18s vs 19s - you'll save a whopping $100 on a set of Conti DWs and a whole $225 on MPSSs. It will cost $700-1000 to buy a set of 18s. My math skills say it will take at least 7 sets of Contis to break even, or 3 sets of MPSSs (which I won't be buying anymore).
Plus I already have a set of snow tires sitting in my meager 2 car garage. Another set would eat up more space. I'll probably dial up more camber in my next alignment but I'll have to keep it reasonable for daily driving. It would really suck to have dedicated track tires and the only mileage on them is track time and the edges wear out with lots of other tread left. I guess the good news with that is I'd pay for the conversion to 18s faster.
DEing is a slippery slope, esp if you continue to drive on the street. Hard to find the right amt of compromise between street and track.
I'm typing this from KC as I'll be driving Kansas Speedway tom and Sun. But not on these tires. Punkin is currently sitting on jack stands as I stole her tires to run on Sydney. It's good to have identical cars.
