I have an 2015 IS350 F-Sport AWD that I just purchased with 35k miles on it from the Milwaukee area. I would like to get the following air suspension kit:

I am new to air suspension and I plan on having a professional shop install it. I only have experience with coilovers installation and adjustment on my '01 IS300. So, I have a couple of questions:

Should I get the 5 or 7 port tank? - would one of these be the "exhaust" port?
1 or 2 compressors?
Should I also purchase some other suspension parts to have the shop install? ex Camber Arms or control arms

I don't know exactly what rims I will be running in the future, but I know that I plan on getting 19 or 20" rims. I would be interested in running negative camber, although this is my daily and I would like reliability over anything else. Any opinions or comments would appreciated, thanks!

1. I just finished up an AirLift install on 2016 FSport.

You dont need any extra arms unless you need negative camber for wheel fitment.

I was able to do everything without drilling any holes in the frame.

Run everything interior. Wires on passenger side and Air lines on driver side. (It may be a good idea to run the fuse wire on the driverside). There are grommets on each side with a nipple you can cut to add wires through the fire wall.

I added a 2nd compressor to make air up recharge faster. It also requires an additional harness kit.

In addition I added isolator kits to each compressor that reduces vibrations

The tank I used has 5 ports and i still have 1 plugged port when using 2 compressors. You need 1 for each compressor (1 or 2), 1 for all the manifold which feeds all the wheels, and 1 drain (bottom)
