Well, Summit Racing is usually spot on about vehicle fitment. I'd feel comfortable dropping the nearly $1K for the kit.

Has anyone tried the "Wilwood Disc Brakes 140-10094-R" rear conversion kit? Summit Racing tells me this will fit our 97' Silverado. I would love to do away with those rear brake shoes if it does. :)

Are those for 5 lug or 6 or are they universal? But that’s pretty decent price but it’d still need to be less for me to option it and if you’ve already installed was it a do it yourself or a more shop did it deal?

That won't fit a GMT-400. That kit is for a C10. Wilwood doesn't have any rear disc brake kits for our trucks yet. Go check it out on Wilwood's website. Don't rely on Summit for fitment.

Little Shop Mfg has a couple of big rear brake kits using Wilwood parts, but it's not a kit from Wilwood. And yes, they're mega dollars ($2000+)

Whatever kit you choose, if it's aftermarket parts (Wilwood calipers, rotors, etc.) then be sure you inquire about replacement parts. Obviously the pads and e-brake shoes, rotors, caliper rebuild kits, e-brake hardware (springs, retainers), hoses.. because you'll eventually need them, and aftermarket stuff often isn't available many years down the road like OEM stuff will be.

Apparently, you have a C1500, since this kit is for 5-lug axle shafts.

I thought GMT400 C1500s used a 5 X 5 1/2 bolt circle. These rotors are triple drilled for 4 1/2", 4 3/4", and 5" inch bolt circles.

For a thousand dollars, you could swap rear axles, get 11.x Duo-Servo rear drums and the much-stronger 9.5" ring gear axle assembly; and spend the rest of the thousand on 5-lug axle shafts to keep your existing wheels. Or spend a little more and get front hubs with 6 lugs, and 6-lug wheels.

You'd eliminate all the disc-brake conversion problems, probably have stronger rear brakes than the 12" rotor aftermarket kit, and retain OEM parts compatibility.
