ELBJ needed with V8R control arms?
 

I’m going completely new on my V8 Exocet suspension, down to the nuts and bolts. This will be 99% street and probably a pretty even mix of highway and city driving, but there’s a lot of unpopulated roads with hills and curves where I live that I’d like to take advantage of. I also wouldn’t mind trying out an occasional auto-x event locally. Due to this, I think I’d be okay with the Dual Duty alignment specs listed on 949’s site. However, I’m starting off with such a huge change from a stock Miata that I’m not sure if I’ve actually reached a point of TOO much adjustability. Is there such a thing? :D My main question is with the additional adjustability of the V8R arms, are extended lower ball joints needed to hit my intended alignment specs? Is there any downside, such as not being able to adjust back from having too much camber?

I’ll give a rundown of my chassis setup in case there’s any other changes or suggestions that come up. Estimated final weight is 1800-1900lbs. Planning on control arms being flat angle or less, doesn’t need to be excessively lowered.

No need for elbj with those arms. I have the v8 roadster arms and there is a LOT of adjustment.
I have experienced the elbj’s wearing quickly. Have had good luck with the Supermiata lower ball joints.

That’s about what I expected. How far out did you start off with your rod ends adjusted?

About 1/2” of threads showing. The lower ball joint is in about the middle of the adjustment. 3* of camber. I do have kiesler spindles that add some camber but there is a lot of adjustment.

I have also found this. Have gone through two sets of elbjs in 2000km and looking for replacements again.
are the SM BJs you had good luck with the Extended ones or std length?

The 2 sets I wore out were Bauer.
I was unaware sm had ext lowers but see they do.
I am using there standard length at this time

V8R confirmed no need for ELBJ’s with their control arms.
