I got the C4 rear in four boxes yesterday. I just got finished putting it back together and mocking it up under the frame. I have a question. I know that typically you are suppose to have a slight angle to a driveshaft going into a rear end. Does that really matter on these as the differential is in a fixed position? I'm wondering if it can be near straight or angled up toward the rearend from the transmission? My trouble is....My transmission snout is going to be much lower than the pinion on the rear end. I'd rather not have to lose floor space by raising the transmission. Will it matter if I have to angle the driveshaft up to the rearend instead of vise-versa? Also....I saw where someone made a comment on the forum, that the propeller shafts need to be angled slightly down. What about angled slightly up as long as I have plenty of travel for the coil-overs? Any idea just how much travel I should allow for? I'm using Aldan's for the front and most likely will use the same for the rear.
