El Zombo

Hi,
I'm putting together a plan to rebuild the suspension on my daily driven 2014, MT, Z with the sports package. I'm the original owner, the car has 70K miles and it won't see the track...I just don't have time for the maintenance track driving requires. I like a firm ride and I've driven cars with poly bushings. I'm looking to improve OE performance and make the car handle better and more predictably.

Here's the plan:
Z1 Motorsports front upper control arms, traction and camber arms
Eibach Pro Kit 1" drop w/springs and sway bars
OE type front lower control arms with whiteline bushings
OE type rear upper control arms with whiteline bushings
Whiteline front and rear sway bar end links
Koni Yellows w/ OE type strut plate and shock bushings
Whiteline differential bushings
Eibach 15mm spacers x4

I might replace the LSD while this is happening, but that depends on funds.

Is there anything else in the suspension I need to replace? Do the rear lower control arms have inner and outer bushings as well? Should I replace the rear crossmember bushings as well?

Anyone done this?

Thanks, everyone.

Hector
