Noob suspension questions

Just wanted to get some input from the folks that know so I don't mess anything up. I've done a lot of reading and searching and I'm trying to double check myself before I start any work.

Here's the situation: I've got an '05 6mt G35 coupe on 19s with stock suspension and approximately 70k miles, I'm in Iraq right now and trying to get everything ready and waiting so when I get home it's all set to install and drive (after an alignment, of course).

Already ordered:
-BC Racing coilovers
-20" Work T1S

Need to order/to-do list:
-SPC front and rear camber kits
-Fender roll
-Tires, but that's a worry for another day

Now what I don't know is the following:
Being that the car has 70k miles and is a few years old now, what should I be wary of during disassembly (other than seized bolts and the like) and what else should I be replacing/checking while I'm at it? Any bushings or other normal wear parts I should consider having on hand before I start? If the car's down for a while waiting for parts it's not the end of the world, I've got another vehicle to drive, but after driving the POS vehicles over here I really miss my G35 and want it back up and running as soon as I can complete the work.

This is the first time I've done coilovers for a car, I've done quite a few suspension swaps on trucks with leaf and coil springs but this is new territory for me so any input is welcomed.

hmmm from what i know you shouldnt have any problems with anything if everything is installed correctly, ive read about a couple people having issues o squeaking sounds because of a loose rubber piece or sumthing but i think BC fixed that issue with all thier newer products...that being said im not a suspension expert...but anyways good luck with everything!!!

Depending on how low you want to go you may want to consider spending extra and going for SPL fronts, SPC fronts with shims can supposedly be a pain to install (I am running mine without the shims).

There's two sets of perch collar adjustment for the front, make sure you adjust the one for the height adjustment and NOT the one for the spring load...they should already be pre-set from BC.

The rear is a little confusing, search around for pre loading the rear and you'll see what I'm talking about, I'm just kinda lazy to look for it.

Thanks for the replies guys, much appreciated. And Deezflip, I think I saw a thread talking about the rear and was confused just reading it but have it bookmarked for later. Thanks for the info on the spring load, will keep that in mind.

For the front camber is there any difference in performance/adjustability between SPL and SPC or is just easier to install the SPL?

Quite a few people cite that the SPC kit knocks if you are low, if you want more info run a quick search about SPC knocking and you should find a good amount of info.

As much as I hate bumping old threads, figured I'd put this back up the top since I just finished my install in the garage.

1) The BC Coilovers were very easy to install, and I feel pretty damn for getting it done on my own with a basic set of air tools and no lift, big plus for doing things yourself.

2) The SPC camber kit is not yet installed, I put the BC's on at their factory settings and will wait a week or two for them settle before I install them, but looking at the clearance that I currently have I dont expect any rubbing or contact/knocking issues.

3) The BCs in the rear are already plenty low without making adjustments, I'll probably drop it a little bit more but on 20s it's already less than a finger-tip gap between 35 wall and fender.

4) If you're not sure what you're doing but think you can pull it off, do it yourself.

5) The rear install was very simple, there are pictures online of how it should look so that you don't do something stupid and install it upside the down the first time, like I did on the passenger side, can't comment on adjustments yet as I haven't gotten there but there are enough threads to do it right, search before you install.

6) I'm home from Iraq, drunk as hell, and have my G35 sitting almost the way I want it, I'm a pretty happy guy at the moment. Cheers.

Thanks for such a great forum, message board, and source of information, I'm gonna go pass the hell out now! (This was definitely a 12 beer job if you're in any way related to the Irish)
