Got some questions before lowering!, Help would be appreciated. Options

[bmrabb]

Hey everyone, I was thinking of lowering my new Celica (gotta change my car info) and I just wanted to ask a few questions before I ordered things.

I already used the search function and found some info but just wanted to make sure I'm getting the right things...
I've heard that when changing out springs, it's a good idea to get new "bump stops"? I'm going to post pictures of front and rear suspension below... if someone could let me know which part it is I need, I'd appreciate it!

Rear:

I was assuming that Bumper Back (#18) is what people refer to as bump stops... but I'm not really sure.

Front:

With the front, #14 is the Bumper Back... but like I said above, not sure if it's the bump stop though.

Other than that, I plan on getting Tanabe Springs (DF210 Series) which state a 2.2" rear and 1.5" front drop. I've also read that camber isn't heavily effected by dropping our celis... but are camber kits recommended?

Thanks to anyone who can lend me some info!
