40* might be a bit extreme on those cv's. i ran mine with a max of 35* on my busa for 3 years. it does run higher temps at 35* where 40* will be a touch hotter. i have never tried 40* so i cannot say for sure. i lowered mine to 30* with my current motor. only thing getting them hot now is my down pipe lol

I will tone it down on the angle.  I will max it out at 35* to keep things somewhat in the safe zone.  Maybe 36* to live life on the edge.  LOL

 ;) ;D

the pic of your truss idea for a-arms looks good.

lance is right on the twist as well as bending moment.      just for example.......enemy had lower a arms with a single piece made out of 1.5" od .25" wall 1020 dom. i mounted the shock close to center as you have done. i questioned if that 1\4" wall was strong enough waaaaaay back then! lol it wasn't, he bent it down apprx 1/8". so built new ones  with a brace. now you have seen my current rear a arms with 2.5 fox shock mounted 40% up from carrier. i used 1 piece of 1.5" od .25 wall tube and 1.25" od .120 wall to make the lowers. recangle 1"x2" .125 wall tube was used as bracing. shock is mounted on the 1.5" tube with an extra wide ( 8" wide i think) shock mounts. the rectangle tube welds to the point to take the twisting moment.  i say all this because mine is much heavier than yours. it has been fine for over 2 years and has been bottomed out a couple times. now having said that i also have a 3 legged lower arm so the twisting moment is support from both sides. could a couple pieces of rectangle tube in each lower for bracing work on your with current shock location?? i think so if you use a long/wide shock tab that spans ateast 3/4 of the lower arm and inner tab weld to the recangle.  still cannot say for sure though.    lancew what are you thoughts on that idea?

Below is a side view of the lower arm that shows the trusset (gusset that reminds me of a truss) that will span appx 70% of the arm.  It will be boxed and have a boss on each side for the  lower shock bolt.

After these discussions, i may be able to move everything towards the center.  I will have to mock in an axle to check clearances.  Very similar to the front lower arm on an a-arm prerunner set up.
Below is a plan view of the lower arm.  The outer x in red is the proposed  shock location.  If there is room, I may move things closer to the center and box things in.  Thoughts?

GREAT info! 
For the exhaust routing.  Below my spool on those brackets there is webbing in there that rests on the horizontal tube.  It takes some stress off the bolts holding the spool in place.

As for the arms.  I totally agree that having the shock in the middle of a bend is bad.  I will have a truss on that arm to spread out the load.

Lance, not negative at all.  That is constructive criticism to fill in my design shortcomings that i welcome very much!
Good eye on the twisting affect.  I will have a bypass shock on the other arm.  I thing that would spread the twist out?  I do have the ability to push the shocks into the center of the arm and build some plate work between the arms so that the loading will be more central to the pivot points.  I just have to clear my axle running in between the coil over and the bypass.

Looks as if I need to get the cv's and axles in place to line this out.
