Spacer for the wheels? I used to be a big hater of spacers but this Tahoe has changed my perspective of that. I've had 1/4" spacers on it since basically week one without any issues and I beat it on the regular lol.
I haven't had any issues with drilled/slotted which surprises me with how I treat stuff but I think part of it is due to having the manny tranny. I don't have to use my brakes nearly as much as an auto.
@randeez brought up a great point earlier about getting the brakes hot with aggressive braking and then sitting on them at a light causing warping. In my case, I would typically compression brake a tad (especially when towing) and save the brakes causing them to not be as hot plus when I get to the light I don't need to use my brakes to sit still because Florida is flat earth territory.
Uhg Covid still ******* me off, I want to order that $193 Powerstop kit but it won't ship till Mid Jan which is too far so, I think I'll do OEM rotors and Powerstop pads coming to $266 total but it will be here in a week or less from Summit and OEM rotors are probably the best option. This thing is gonna stop hard AF! 4pot front, NBS 2pot fronts in the rear with a 13" rotor, stainless lines F/R, and Hydro boost in a 4,800# truck. The front brakes are rated for a 6k# truck and the rears are for a 6,400# truck so this mofo ought to stop good!
