New owner and need advice(coz im new to it all)

The CPP kits run the D52 calibers. I have had good luck with their 4 wheel kit. I would recommend you buy your own bearings and replace the ones that are supplied they are cheap junk and don't last to long. Other than that the brakes have work flawlessly. I purchased the zero offset kit for stock spindles for my nomad but have not installed them yet. Willwood also makes a nice brake kit for stock spindles but a little more pricey. I actually updated my zero offset kit to run willwood calibers they are offered as an option with the CPP kit.

The problem with the 68-72 Chevelle rotors and calipers on stock spindles is that they move the wheel mounting surface outboard 7/8" per side which is significant imo. The if you use tires of any size (like a 225+) you can have rubbing problems with the tire outboard so far. With typical zero offset wheels the outside of the tires would be over 70" and it will probably rub the fender on turns with the suspension compressed some. It's especially bad if you plan to drop the car at all with cut springs. If you compensate with wheels with more backspacing it helps and doesn't look so weird.

I have ran 225/70/15s on the front of my 56 for over 20 years with no rub issues. I believe 57s are more rub prone than 55/56. I always enjoy having this conversation in the presence of one of my cars. When this topic comes up, I tell people how wrong my car is and have yet to have anyone say anything other than to say, it looks fine to them.

Here's exactly what a 68-72 Chevelle brake setup and an 8" rally wheel looks like. I don't remember the tire size or the wheel offset, but it was a common wheel from the 60's and I'm pretty sure it was from my '69 Z/28. I think it's a problem. Maybe it works fine if your fenderwell is 3-4" above the top of the tire. Buy imo it would still look bad.

I remember those tires OEM from my Moms 1971 Buick Lesaber Custom 455 Uniroyal L78 15s, way too big and tall for the front of anything short of a land yacht.

They made the "Belted Jumbo 780" in many sizes and I don't see anything in the pics that suggest it's an L78. Even if it is an L78 (I don't know if it is) they are equivalent to a 235/75 radial tire and are about 29.3" tall. That's 1" taller than stock and only .5" radius. How much would it really change if it was a 225 tire or even a 215 tire? You already said recently that you run a really narrow tire on your car so that's why it works.

You don't seem to understand the issue. Look where the sidewall is. Look where the edge of the wheel is. When the suspension is compressed on a stock tri5 the top of the tire moves outboard. The fender gets closer to the tire. It's the same as dropping the front suspension, which we know can be a problem. Worst case the tire hits the fender and tears it up....best case it just looks stupid.

Looks nothing like my car, not everyone wants to run 8 inch wide wheels on the front of their car or hack it up for a c4 job.

Same wheel mounting surface width as yours though, which doesn't work with tires most guys want to run and a lowered suspension.

No, not "everyone" does. Guys stuck in the 60's that don't own a digital camera or a cellphone or even a touchtone phone (LOL ) don't want the more modern looks of wider tires and larger wheels, nor the greatly improved performance that a C4 suspension provides. They run wimpy 5" wheels and 195 tires so they don't rub with the 7/8" offset hubs and balloon ATV-type tires on 15" wheels in the rear. The stock suspension on these cars sucks, and everyone knows it that's why they upgrade them. Some guys don't understand that time and technology has long passed them by.

Hey markm, look at this C4 "hack job"! Let's see yours!

The "chevelle" based disc kit with your stock 15" (5" wide) wheels will work just fine. The problems occur when you try to run 8" wide wheels or huge tires

My point exactly even 6 wide wheels and 215 or 225 of the 70 series are no issue and look fine.
