Default Adjustable or non-adjustable LCA?

I was given a set of poly/rod adjustable lower control arms from a friend of mine that need to be reconditioned and powdercoated but would be brand new for less than the cost of new. I was planning to use roto joints on the rod end side and just new poly bushings on the other but yesterday I found a set of silver BMR arms that are poly/poly that have been in the basement for years brand new. Them being silver shows how long I have had them lol.

Car is in sig and in the process of getting a Huron Speed turbo kit and related parts installed. Future rear tire plans are probably 325/50/15s so I am not sure if the adjustability of the arms is important for that or not?

Well are you going to be drag racing? If so, just for fun or competitively? LCA's are usually installed to help control wheel hop. If you a serious in straight lining, adjustable is the way to go. Even more, LCA reolcation brackets. If you just want better hook up and ride better on the street, non-adjustable are a lot more affordable and will still be a BIG difference from stock. If you're wanting to tweak your suspension to get it spot-on where you like, adjustable is still a better choice on street as well if you care about the fine-print.

You can't ever go wrong with adjustable suspension. You could sell your non adjustable and coupe some money back if you'd like

You will be fine with non-adjustable as long as you are not lowered more than 1.5" or running a tire larger than 28" if you have the stock rear end. If you have an aftermarket rear (12 bolt, 9inch etc) then the adjustables may not be a bad idea to make up for any variations in mounting locations of the brackets on the aftermarket rear.

My car originally had adjustable LCAs on it, but I took them off and replaced them with non-adjustable LCAs due to the increased suspension noise from the adjustable versions.

I'm actually planning all 3 of those so I guess I will just stick the adjustables on then lol.

Sell the NIB non-adj. LCAs , and recondition the adj.LCAs. Lowering won't likely throw off the centering of the rear wheels enough to need adj. LCAs, but large dia. tire and/or a 9" or 12 bolt rear end probably will.

This is definitely unusual because as long as the mounting points use the same parts (poly bushings, rod end, etc, etc) there should be no difference in noise or ride quality between the adjustable and non-adjustable LCAs.
