Coilovers Additional Mods
 

Been a while since I’ve had to ask anything because I can generally find the answer to any question from past threads, but my knowledge is very limited on suspension so I’m finding it difficult as many of the topics get quite involved.

I recently bought some 57xtremes (front 18x8.5 +33 wrapped in 235/40/18, rear 18x9.5 +40 in 255/35/18) and purchased tein flex z to have the car lowered a moderate amount (around an inch) just to have the wheels tucked a little more, as I’ve seen springs aren’t the best route to go, so I waited until I could afford to do everything right. As I understand it, as the car lowers it naturally cambers in, thus tucking the wheels a small amount as I’d like. I planned on getting an alignment as soon as everything was installed, proper balance, etc. However I’m getting confused reading about camber and how it’s best to keep the car in its natural balance of things by installing rear control arms to adjust the camber as well.

Basically I’m just a little lost on what I thought I had at least a beginners understanding on. I’m not looking to ever track the car. It’s strictly a DD, and I live in Florida so the car never sees snow and rarely ever potholes. I drive the car like a grandma under 2k rpms 90% of the time for mileage, just to give a picture of my driving style. So im wondering if rear control arms, replacing the end links, etc is necessary for this. I want to do everything right, but I also don’t want to buy additional parts if they’re not necessary.
If there’s already answers to all this I’ve missed, my apologies.

Just have it aligned and don't worry about it. It's not really a big deal unless you are looking for a specific alignment for track or autoX, or you are really really low.

You already fscked up balance by choosing staggered wheel/tire set. From that i deduct that you didn't care about handling or balance in first place, prioritizing fitting widest tires you can and flush fitment, so not worth overthink. Then just do lowering/camber to get your wished looks of flushness and just dial toe to reasonable values (eg. stock alignment's front zero toe and slight toe-in rear). Flex Zs have front camberplates in set. You'll need rear LCAs to get rear camber adjustability, if changes to rear camber will be needed to get your goals of fitment.

Wasn’t necessarily a lack of care but more so lack of understanding. Didn’t want to buy new wheels and have a huge hit on the depreciation because I don’t really mind having a little curb rash or damage because I’m sure I’ll add my fair share along the way. Found a good deal on these and went for it, as I was able to find a lot others who had used the same sizes and been fine. Not saying I did enough research by any means but I figured I could make it work in the end without too many issues.
Thank you for the advice though, that’s exactly what I was wondering in terms of what needed to be adjusted.
