UCF10 UCF20 suspension

Hey guys I'm new to these cars. I just bought a 1990 ucf10 ls400 and wanting to do the suspension adjustable front and rear. I know battle version do a rear kit but I know nagisa do a front and rear kit. I will be putting coil overs in as well and probably this has been covered before but are there any difference for the 10 and the 20 series if installing adjustable the same. Just there is not much at all in Australia. Any help would be great. Cheers.

20 coils are longer than 10, but they are interchangeable.

I "think" the upper arms from a GS "might" be the same as the LS. If this is true then adjustable uppers for the GS should fit. I'm in the process of confirming this.

the fuca are different. i believe they will bolt up but the caster will change. i compared them a while back.

How bad will the caster be?

Any chance that the SPC FUCA's caster adjustment would counteract this?

make sure you check and replace all of your bad bushings first before you upgrade the suspension.

i'm not sure. i just did a quick comparison and once i saw the difference i left it alone.

it's possible, but it's been a while so i don't recall exactly how major the difference was.
