Mixed signals, extended LCAs only?
New to B-body's but not LT-1s.
Anyway, I see on UMI performance website saying you DON'T need adjustable rear Upper control arms to run their lower control arms only... But then I see from other people that the pinion angle will be way out of whack of you skip the uppers and only do extended lowers?
I have a p71 DS conversion all set up so that's a non-issue, I just need to hear from first hand experience if you need uppers and lower or just extended lowers are ok for centering those rear wheels.
(Spoke with a guy from one of the LCA fab companies but I wasn't impressed with the conversation to be honest so looking for unbiased and educated advice)
