OK I just put my STB in and I have a few ?s about the rest of the suspension stuff that's sitting in my garage....

I got LCAs, SFCs and PHB. Are there stock ones of each of these, or do I just add them? Like, there's no stock STB, I just added it. Does my car come with LCA, SFCs and PHB?

Where are each of these located under the car? Thanks!

 

Your car does come with LCA's and a PHB, those you swap out with the new ones you bought. The SFC are not a factory replacement, you add them on like your STB
LCA's are attached to rear axle and in front of it in a perpendicular way
The PHB is to the back of the axle and perpendicular to it
THe SFC basically goes from the front subframe to the from the rear lower control arms
Hope this helps, a search will maybe bring some pics or go to BMR's webpage, they have a photo of almost every component installed.

 

WHoops, the PHB is PARALLEL to the rear axle sorry
