I had already ordered a Regular DM for my 70 2 wd Blazer then decided to go with the C4 because once I got Strong arms, disk brakes, drop spindles all to change out the drum brake 6 lug set up it would be cheaper to go C4. Even if in the end the price ends up the same for the two set up who can argue the C4 is not a better set up. Also keep in mind Nate did not just transfer the geometry info from the Vett over to these trucks and sell it as is. He took the time and knowledge he has learned over the years and improved the spec's to work much better in these trucks. I know people are saying how can he build better then GM with all their money they put into things. Well he doesn't, he takes into consideration the roll center, weight, motor placement and tons of other stuff I don't understand to make it work great for us.
Sorry Man crush over
