I've never had run flats. Anything bad about run flats?
Yes and a lot. Flat fix makes a mess of the tire and rim, it can be cleaned off the rim but it's hard to get the inside of the tire clean since it bonds to the rubber.
Runflat's are a compromise, they have sidewall structures stiff enough to hold up the vehicle without air. That means the rest of the tire needs to be designed to accommodate that while still performing. There's no free ride, you lose performance and comfort with a runflat design.
As for a spare, does anyone know if they put anything in the spare well that would prevent you from adding your own spare? I understand that with the Brembo's the 18" steel spare won't work but an aftermarket 20" x 8" wheel or a takeoff 20 x 8" with a 265/50-20 tire should fit around the Brembos and fit in the spare well.
