Buddy, you sure needed to search through this forum, because I did all the work for ya
Project: StanceParts Air Cup system
stanceparts all 4 corners. Pretty sure i'm the only one running all 4 corners, at least with SPL parts, according to them
Lessons:
- You don't REALLY need all 4 corners, fronts are usually fine
- Need machine work for the rear cups if you intend to stick with divorced setup
- If you wanna be low, get ready to trim the lower spring perch
- Stanceparts provided air tank is really strained going all 4 corners. Needs to refill every 2 activations
- Stanceparts provided compressor is loud AF; i get it's part of the game when going air anything, but it's real loud. Mine is hidden under the trunk and it's still loud. If you can, get the stanceparts cups and piece together a larger tank (or dual tank if you want) and spend extra on a newer design, super silent one, i think there are a few out there nowadays
Double check the measurements on the shaft diameter of your coilovers before sending to Stanceparts. You can't re-drill that opening, it's pretty delicate.
