hey guys! so here is the result of my lowering of my '12 gjc 5.7 altitude
I used road magnet 1.8" drop springs on front and back. these guys are awesome and super helpful in replacing the 2.8"s with the 1.8"s for the rear. they even offered to twist custom springs if the 1.8" didnt work out. big thanks to chad at black ops autoworks for all the assistance.
my jeep came with load leveling shocks in the rear so I replaced them with oem non load leveling shocks. I also had to buy the upper mounts and jounce stops. I tried the 2.8" in the rear first but i was rubbing and bottoming out all the time as they were made for the more firm srt8 suspension. Much better now.
other mods include:
ed hansens x pipe -awesome sounds and flow
moes performance ported throttle body - much peppier now
diablo trinity with custom dyno tune - made a world of difference
vvivid 8 vinyl wrap
tinted tail lights and rear markers
I will also be making a strut tower brace soon to eliminate remaining body roll
another trick i learned to help the crappy throttle response is to reprogram the throttle by doing the following:
turn on ignition (dont start car)
wait for lights to go out on dash
slam gas pedal to floor and hold for 30 sec
keep holding throttle and turn ignition off and hold for an additional 30 sec
then slowly release the pedal
this will reprogram the throttle and make it much more responsive.
drive it like you stole it for a few days and it should reman like this.
other wise itll reprogram to the more efficient slower response.
