Ahhh... The front bar. OK, Got ya. Interesting. I misunderstood. Either way, good fix!
I'm anxiously awaiting front spring rate reviews!

The front springs got a good test today, a 65mi. round trip to work & back on winding back roads.
Ride is firm but not harsh (similar to my friends 3500HD Duramax truck... your opinions may differ as I am used to my Firebird that also runs an 800# spring.)
I ended up taking 2 clicks off of the front shock compression from the previous best setting (was 13/18 now 11/18 clicks)
It did not significantly change the handling, but removed a harsh feeling on choppy road surfaces.
Tomorrow I will remove 1 more click of rebound from the rear to see how it reacts.
I know it prefers less rebound stiffness on launch & gear changes, so fingers are crossed that it helps both issues.

I figured I would post some updates....
After a summer of driving, I got a good handle on my likes/dislikes.
The camber is a little aggressive & beating up the inside of the front tires.
I think I'm going to reduce it a bit.
I further reduced both shock compression & rebound a bit more for reduced harshness.
Although it feels slightly less responsive, the ultimate cornering ability does not seem reduced.
I still want more rear traction (in both acceleration & cornering), but it appears my only option is a race tire, but the NT05 is wearing very quickly as it is.
The 4.10's & .65 OD is not exactly tailored for extended highway trips but it great for all around use & I can drive just about everywhere in 6th gear.
Only at 80mph on the highway do I wish I had the .5 OD. Some planned engine mods may cause me to drop the rear gear to possibly a 3.73 in the future.
Now for the winter changes....
The performance is good as well as the mileage, but I cannot leave well enough alone.
I found an LSA supercharger so why not try to add another 200hp.
It is proving to be rather crowded getting everything to fit under the hood.
Saty tuned for more updates on engine mods, fuel system updates & overall fitment issues.

Let me know...
I learned many things the hard way & I can steer you clear of them on your build.
05-24-2022 #67im on the edge of going coil overs or not for alice. i need to re-read through your build to see your spring rates
...life is too short, live for today, tomorrow isn't guaranteed

I made a lot of progress & was driving it in June.
I decided to color match the supercharger.
It took a lot of mods to fit everything.
The coils had to be lowered to clear the fuel rails, but it then put them closer to the heater box, where room was non-existent.
The reservoir for the PS had to be moved & a custom tube made to reroute the fluid return.
It clears the pulley/belt by about 3/16"
Because of the cable throttle body, there were some fitment issues here also.
After making a new cable pin, it clears.
The intercooler was another issue as the radiator is now inside the rad support to clear the engine & the AC condenser is in front against the grille.
This made me look into a refrigerated intercooler similar to that on the Dodge Demons.
What made it more interesting was the truck has metric AC lines & the aftermarket parts are US dimensions, making adapter fittings unavailable.
I chose to install an isolation valve to turn off the cab AC for max cooling during race use.
Here is the heat exchanger located under the front bumper.
It cools very well & I can get 40 deg air temps entering the engine on a 70 degree day.
The water contains glycol to keep it from freezing.
The unexpected benefit is the cool air temps condense the mixture & reduce the boost level.
Boost dropped over 2lb while increasing HP... a good excuse to add a 22% overdrive lower pulley.
This is everything crammed into place.
Now I am back on the suspension...
After making it handle well, then adding power, I cannot get the truck to hook, even with slicks.
I also need to pull some rear gear as I now need 5th to get through the quarter. 4th gear is only good for 128 mph
I'm currently working to increase suspension travel to help weight transfer without hurting handling.
There was only 3" front droop from ride height. On launch you could see the slicks wrinkle, the front suspension top out & instantly the rear tires smoke.
I'm doing some alterations to the upper control arms, ball joints & shock length. I currently increased it by another 2.5", now limited by the outer tie rod (rod end) binding.
Next will be altering the tie rod shape to get some more travel, up to the point I run out of ball joint angle.
