Stock rotor top hat thickness?

[bogle]

Does anyone have a caliper (for measurement) and a stock front rotor laying around? I’m curious how to thick the top hats are, a pretty precise measurement would be ideal. That is, how much do the top hats push the front wheel out from the hub? It’ll probably be somewhere between say 4mm and like 10mm

My bbk has 7mm thick top hats. Im wondering if I’m running more offset than stock because of the top hats

According to Stoptech templates, they are 5mm thick vs 9mm for stoptech, take a look here:

So your brakes with 7mm should make your wheels move 2mm out

I'm sorry I just saw this. I'll be able to check this wknd if you haven't already gotten an answer by then. My rule of thumb is that aftermarket alum rotor hats is +5mm to wheel offset.

Sweet, thanks!

For posterity, I am running racing brake 328mm rotors with an old brembo gt kit (“lotus” calipers). The top hats are 7mm thick. The original bbk rotors I removed had 12mm thick top hats.
