Decision: 5x4 (SBP) or 5x4.5?

I’m pretty sure it has nothing to do with ‘cheap’, and with a response like that I’m also pretty sure you didn’t really read any of @72bluNblu ’s post. He’s done a lot of work with brakes and conversions and I for one at least consider his opinions and input invaluable.

I’ve had Kelsey Hayes 4 piston (which had pistons seize up), weak drum spindles converted to Will wood disc (which had pistons seize up), and have also done several oem 73’ and up disc brake conversions on A and B body cars, and couldn’t agree with bluNblu more about which ones install the easiest. people talk about weight, how much are you saving in pounds and does it really matter anyway?
Having had them all, and Dollars to donuts for all the reasons listed in previous post’s my vote is for oem 73 and up disc brakes, with rear drum.

Stroked340 is one of those guys that thinks if he spends the most money he will always get the best parts. He also thinks he’s better than everyone else if he spends the most money.

Sadly, he doesn’t have the best brakes or the most money, but he’ll keep trying to convince other people to make the same choices so he looks better. He calls me “cheap” because he can’t make a good technical argument to support his opinion, so the best he can do is call me names. Of course even the “cheap” thing is BS, the DoctorDiff 13” cobra style kit I run on my Duster was more expensive than the basic low end Wilwood kit he runs.

As far as weight goes, even if the Wilwoods save 35 lbs vs the stock 73+ disks that’s not something you’ll ever notice on the street. It’s unlikely most people would even notice it at the track. As part of a whole car lightening effort it would help, but by themselves it’s almost nothing. Do you notice when you put a load of groceries in the trunk? Is that worth an extra $300? For a street car I would much rather trade a few pounds for better reliability and more robust braking.

The other thing is, the new Wilwood hubs will not fit ANY of the original mopar SBP wheels or ANY of the reproduction SBP wheels. They require a hub bore of 3.050”, which none of those wheels have. Even the factory BBP wheels have a smaller center bore than that. This has been discussed before here

Small Bolt Pattern Wheels Don't Fit Wilwood Disc Conversion

If you have to buy all new wheels anyway you might as well upgrade to BBP.
