Upgrading Rims and Wheels for a 1968 Dart GTS
That's how I'm upgrading to 15's. Kelsey Hayes manual 4 piston calipers work great. Even having Mosier narrow a Dana 60 for me and drill axles to sbp for me. They said no problem for well over 500 hp with sbp and good studs. Including handling or the fairy tale of breaking wheels off... Unless you run old rusty bad wheels... Lol!
It's not the wheels that break off, it's those wimpy 50 year old 7/16 studs. If you're installing 1/2 in tho, they may not seat right in the 7/16 sockets.
I too have the KH 4-piston brakes and as a streeter, I've never needed more. I do however have 295s in the back, and the 10" brakes back there have zero proportioning.
BFG 295s are not hockey pucks! I can only spin them to 80/85 mph,lol.
Blu is right, BFGs are known to be slipery, hence why I have 295s. That's what it took to keep the back, in the back, for this streeter. I like kidney-bean aluminum slots. I had a pair of 15 x 10s so I made it work.
But 275s really sucked.
With a 360 and 3.55s, 245s were a joke no matter what the brand. She still went 12.9@106 with a 270 cam @3650pounds. I don't actually know when she stopped spinning, as the tach was on 7000 most of the way, and I only made the one run,lol; that was good enough for me. I think those were called RoadHuggers lol.
