Cost Effectiveness 13" C4HD vs 13.5" C6 Z51
 

Which offers better bang for buck.

both about the same, depending on where you get your parts. just get the Z51 and be updated

If you can fit them go with the Z51 brakes...they will have a more modern caliper design, larger pad surface area, and the larger rotors.

Well im hoping they would fit behind 18" C6 rims. If not id be scratchin my head.

They'll fit 18"s, go for it.

Can you PM a price for one of your conversions. Thnx

Will the z51's fit under 17" wheels?

.
 

I measured 7.75" from the spindle center to the outside of the caliper so it's my best guess that some 17" wheels will fit, some won't. C6s have 18" front wheels so I know they will fit in there
