C4 vs M2

[regan56]

ok guys and gals.

what can you tell me about the C4 and the Mustang2 setups and why one is better than the other. honestly, i don't know.

My original direction was the M2 from Heidts, however that may be out my budget range. looking onto the web i have been reading alot about the C4 IFS than can be had for a fraction of the cost, like finding the parts from salvage yards and the crossmember from Flatout, or maybe the entire kit from Flatout (or similar).

i understand this doesn't lend itself well to my recent bolt pattern discussion from earlier, but i suspect there are options to compensate for the 5 x 4.75 bolt pattern on the C4?
