Posts: 105Do later model front lower control arms from say a vy fit in a vr/vs? I was going to grab some from a wrecker and test it but to be honest if someone else has tried it already it would save me wasting money.
March 5, 2015 at 11:06 pm #2069From memory they are different Whiteline part numbers, so I would lean towards no.
Yep different mate, VR/VS Has a different ball joint and just an overall different design, VT S1 Has the same actual arm as VT S2/VZ but a different ball joint and they also come in a Left or Right.
VR/VS
Later VT S2/VZ

Posts: 105Yeh i had a quick look at the whiteline site too. Obviously different arms but the question is how different? Bushing used for the inner mount is the same which suggests it’ll mount up (first hurdle). I haven’t been able to find any dimensions for the arms to know distance between inner bush and radius rod bush for example. If that were too far out then it wouldn’t work. I also don’t know overall arm length differences. Ball joints don’t seem a big deal as i could potentially use the later model knuckle too?
Basically i’ve found some aftermarket arms designed the for 04-06 GTO. Wondering if they’ll work in a vr/vs track car. Doesn’t seem that anyone has looked at the differences in detail though so i’ll have to see if anyone is willing to donate free/cheap so i can take some measurements.

Posts: 105So i bought some cheap arms, knuckles and radius rods to test. Arms seem to be basically same length and distance from lower arm mount to radius rod seems same. However there is a bit of a problem. The VR/VS have a doglog in them. Where the VT-VZ arms are straighter.
With VT+ arms in place the stock radius rods are too short, but the VT and later radius rods are too long. The later radius rods literally won’t fit into the k frame.
Potentially adjustable radius rods may work but don’t know if they can be extended longer than stock or if they only get shorter.
August 23, 2015 at 3:52 pm #8663If you use the VT arms you might be able to get more caster, with VS arms and adjustable radius rods, you’re limited by how much caster you can put in as the wheel rubs on the guards. With the VT arms it looks like the wheel starts off further back in the wheel arch so you could get more caster – possibly…
Can you tell if the VT wheel hub bolts straight up to the rest of the VS suspension? Struts are the same but is the flange and ball joint location compatible?
P.S. Apparently the VT S1 ball joint connection to the hub is pinch bolt, VT SII onwards is tapered.

Posts: 57A guy on the VG-VS holden utes facebook page has run this setup before and i will be going down this path soon. Will be running vt-vz lcas, knuckles and hubs with adjustable radius rods. Will put up pictures once i get around to doing it.

what’s the reason guys go VT LCA’s on a VS? I know on the vn-vp they do it to gain track but the vt and vs arms appear to be the same length?

Posts: 57My reasoning is you get the least steering lock with modified knuckles with vs lcas because of the lock stops. Apart from that I’m not sure, maybe because the later model arms are cheaper?

Posts: 105I haven’t tested whether vt+ knuckles will work on vs ball joints but more options for aftermarket knuckles with improved bearings and roll centre/camber adjustment for VT+ than Vr/Vs. That’s if you’re getting serious.

Posts: 57I’ve been talking with a guy on Facebook that makes modified radius rods and knuckles.
He was saying that he’s working on a fully adjustable heavy duty front suspension kit for Commodores.
