Added a 20" spare tire so it will work with the front Brembos. And yes a 275/55/R20 will fit in place of the 265/70/R17. You just have to make sure you move it so it doesn't catch on the heat shield on the way up.

Finally also got around to do the data logging for my DiabLew tune on Sunday. Lew did great job turning the files around in less than 24 hours, so loaded them yesterday.

Such a big difference in the way the truck behaves! Money well spent once again.

BTW, forgot to add that since Lew raised the idle rpm, the slight vibration the truck had at idle when in gear is also gone. At just over 100K it does need plugs, too, and those are on the to-do-list. And of course I will also get a set of new wires since I don't think I've ever been able to get all wires out without breaking at least one.

Does it show more tire when looking at it from behind vs the factory spare?
