Disc brake conversion (70 Dart)

I'm short on data? Oh, you mean your made up data. Nice try though.
I am and actual Mechanical Engineer in automotive.

For a guy with a 500 hp brake dyno, you seem to be short on data. You don't need to calculate anything, put a '73+ mopar caliper on your dyno and give us the numbers. Heck, put a Wilwood Dynalite caliper on there next and completely settle this. Should be pretty easy for a guy with a brake dyno to get all the information we need.



Pretty much none of the stock wheels will fit the Wilwood brakes anymore. The hub bore for the Wilwoods has to be 3.050" with their new redesigned hub, and that's larger than pretty much all of the stock wheels. The wheel studs used are also 1/2", so they won't usually work with stock wheels because the stock SBP studs were 7/16". And the rallye wheels don't clear the calipers.

So, there's really no advantage to using the Wilwoods to keep the SBP. You have to buy new wheels anyway, might as well go BBP. Heck, with a hub bore of 3.050" a lot of BBP aftermarket wheels won't fit either.

You wouldn't understand the data anyway. You're not a real Mechanical Engineer. You just play one on this site.

I have tested every GM, Ford , Chrysler brake package available since 1996 and a lot of foreign OEM's. And a lot of brake packages suppliers try to pitch to OEM's. The Willwood's will work better reliably than the 40 year old tech. You seem to think the only thing that makes a brake package good is the size of the caliper piston... I doubt you could understand much else. You surely don't understand why even clamping force is a benefit.

Where's your data, saying they are junk? Oh, it's just your opinion.

The OP can choose to use the old brake system and most likely it will work fine for tooling around. It's his budget. He should plan on spending $500-700 when it's all said and done keeping the old design brakes if he wants to replace everything with new and rebuilds.
