Having a hard time locating an ss/rca kit for my 1st gen, anyone know if the 2nd gen kits work for my car? Thanks in advance!

 

The regular front RCA/SS kit (NOT negative camber as I have minimal experience with those) will interchange without problem between '89-00 LS400s. The stackable RCA figs sells should work just fine.

The rears may or may not, I can't recall.

 

2nd gen negative camber RCAs will NOT fit your 1st gen. i don't know of any companies that sell 1st gen NRCAs, even japanese companies.

check serialnine in canada. they have applications for LS400s but mainly 2nd gen. you might be able to talk to them and see if they can make a set for you. that or buy their upper control arms and do negative camber that way!

 

That's interesting though considering the bolt holes for the LBJ are the same size.

What if you have 2LS LBJs on your 1LS? Sounds like one of those things that should work without issue but hasn't been done yet.

 

hmm you may be up to something PD. if the bolt spacing is the same, i don't see why a 2nd gen NRCA would not fit a 1st gen! i always thought it was a different spacing. i know 1st gen ball joints have a bend to them unlike 2nd gens.

 

I think you have that backwards, 2nd gen have a bend to clear the brake calipers, 1st gen dont. Hence the need for 2LS LBJs when doing a 2LS bbk on a 1LS.

 

oh i was talking about the bend going upwards. i never noticed it also bends sideways!
