67-69 13" front C5 Brake Kit $575 on Ebay

[Mark Hamburg]

You guys looking for cheap big brakes need to check this out: Fully prepared kit with rebuilt C5 calipers powdercoated in red; CNC-milled mounts; new drilled, slotted and zinc-coated 13" C4 rotors; new bolts, bearings, seals and DOT stainless braided lines. Uses your existing 67-69 disc or drum spindle, but requires drum brake hubs. Rotors are supplied already milled for stock drum brake hubs (you usually need to cut the diameter down to 6"). Ready to bolt on! Got my set today! Requires about 3/8" clearance between back of wheels and calipers. TTII's clear, others need to check. Won't clear a TT D without spacers. Requires at least 17" wheels. Kit is top notch for the money! Ebay Item # 200097865567 .

Now all I need are my 17" wheels!

Price is great, but what do you do when you need a new set of
rotors?

I am not sure why the seller doesn't recommend just turning the hub down and using a stock rotor.

I guess you would just turn your hubs when you need to replace the rotors

[Mark Hamburg]

The seller has drilled, slotted and zinc'd replacement rotors priced at $100 per pair already machined for stock hubs. You can also go the Speed-Tech aluminum hub route for about $270 a pair or this guy has aluminum hubs for $150 a pair. I believe both sets of hubs use standard C4 rotors.

This might be a dumb question but would machining part of the rotor compromise any of the strength of the rotor itself?

[Mark Hamburg]

A totally valid question. The inner opening on the rotors gets machined open far enough to slide over the hub. Conversely, the hub machining approach requires that the outer portion of the hub be machined down to 6". If the bolt circle is 4.75" (not really measured directly across as the hub diameter would be, but just for discussion's sake) and the studs are 1/2" in diameter, that leaves 6" minus 4.75" (measured to center of bolt) minus .25" (half of the stud diameter), divided by two (sides), or less than 1/2" of supporting metal on the outside of the studs on the hub. It just didn't look like that much metal was left to support the studs.
