2 Vane or not 2 Vane - Which Rotor?
 

Looking at Rotors on Napas website:

NB 4885727 $64.99
No ups no extras

UP 85727 $78.99
Onyx guard prevents rust and corrosion on rotor
Out of the box no turn guarantee

NB 4885994 $92.99
2 Vane Configuration reduces temp and increases performance

Which have you guys used?
Ideally I would put on the C-4 HD Setup from Ed but I dont have the $1000.00 as it took $2000.00 plus last week to fix the front end after hitting a curb in the rain.
I have to replace rotors, calipers, pads, bearings and hoses on our 89 IROC and am trying to keep it at $500.00 in quality parts. Basically looking at a stock rebuild.
Thanks for your help,
