Pm sent to you Danny... I want to say from memory, but memory has failed me before, but the total height of the NBS spindle is taller than the factory stuff? Since we are kicking some tires in the thread, how did the tie-rods line up.. taper the same from what you remember?

The tie rod ends up close, the exact location of the tapers is not correct, but its close enough to work for the show truck we were building. All late models use lock nuts instead of cotter pins. We used lock nuts so the exact size of the taper is less important.

In my opinion the CPP modular spindle with the forged hub realy is the best way to go. The other set up can be made to work but there are some trade-offs to doing it like the red hot rotor only 3/8" off the rubber boot and grease of the lower ball joint.

Man this loooks close (size wise) to our stock spindle, its for a 85 corvette..

Vette hub won't work for me, I want 6 lugs!

Basemodel67 why not use a big wheel spacer? This will allow you to use the flat wheel with big back spacing just like the late models do.

I've always heard that wheel spacers are bearing-killing danger magnets. I know they aren't recommended for race use or agressive driving, so I kinda steer away from them.

Maybe I could just cough up big money for custom made wheels like HRE's or Forgeline's that I think can be built with an extended wheel mounting surface and use extra long studs...

Option 2: Could I get a CPP modular spindle and hub and cut down the end of the hub where the dust cap goes? As long as the spindle nut goes on, I should be OK, right???

The wheel spacer will not change the bearing loads because you will be running a larger back spacing with the new wheels. This will keep the tire contact patch in almost the same position relative to the wheel bearings. If you were going to use the same back spacing and use a wheel spacer then you will change the load on the wheel bearings.

The reason the OE rotor and CPP forged hub are tall is because the wheel mounts almost inline with the inner wheel bearing; the spindle nut is just under the dust cap with only a little bit of extra clearance. Thats the strongest place to mount the wheel. The late models mount the wheel out past the bearings causing a high stress bearing assembly. To counter the high stress the wheels have a much larger back spacing in attempt to center the wheel bearings over the tire contact patch.

There is not enough clearance to cut down the end of the hub assembly.
