After a few months of research i went with the lg gt2 coilover and G1 swaybars with adjustable endlinks

fit and finish

everything went smoothly, i had to modify the lower mounts of the front coilovers to match up with my car as well as drill out the hole for the end link bolts to pass through, im thinking it was somehting off with my lower control arms, also tightening the upper mounts on the front coilovers takes some skill, other than that i had everything done in about 8 hours start to finish

adjustability

theres a ton, the sway bars can be stiffened, you can preload the springs, adjust ride height, change the dampening of the shocks. i have mine setup to be .5' lower in the front 1'' lower in the rear, i added .5'' preload to all the springs and 12/12 on the shocks, i like firm rides and think my z51 setup was soft

driving impression

love them, no matter how hard i stop, accelerate or turn the car is level, im on worn out r888s and it was 35* out so i couldnt push the car but i still did 60 on the off ramp with ease (fastest ive taken it with stock suspension was 85 before it started to skid)

its tough to describe the setup, the car is stiffer yet its more compliant to uneven roads, its not like the other coilovers my friends have installed (non vettes) where the increased stiffness meant rattling your jaw on roads. you go over bumps, you feel them but its still smooth, very impressed and they look great thank you adam@rsi and anthony@LG for putting up with my questions and putting out a great setup at a sweet price
