GPvR LCA Compared to GPX
Hi guys,
I know the GPvR has a different front subframe, and different lower control arms that everyone just accepts as better.
I know the subframe is reinforced in some area which is what makes it better.
And I know the difference with the lower control arms is the rear bush that is round rather than square.
But why is this actually better?

Has the droplink mount for the sway bar on it. Instead of on the strut.

Thanks Vectose, that doesn't necessarily make it a better setup though

Re: GPvR LCA Compared to GPX
Might be worth investigating bushes in general, I don't think many answers will be lurking around FTO parts.

Re: GPvR LCA Compared to GPX
The only difference in the arms apart from the droplink mount being welded on, is the tubular section where the rear bush goes on is threaded, so the bush is locked on with a nut.
It wasn't just the vR that got the different rear bushes, pretty sure all face lifts did.
The threaded end helps lock the bush in place so there's less lateral load as well as torsional. I've seen some of those old school block bushes get really fucked up & even twist around in their seat.
This was Shanes race car, fully twisted around 90 degrees - as you can see, that's no good for a bush with an offset hole lol
This one came out of ZFL45H1's car..
And here's the facelifted variant. Also used on Evos & Magnas
Not an FTO, but similar age Mitsi to get the concept.
Then there's always the step up to the Evo arms. Some minor differences between the early models (III, IV, V) but essentially the same as facelifted FTO, but made from cast material, rather than pressed steep, adding more torsional rigidity. Earlier ones tended to be cast iron, while the latter tended alloy to reduce weight.
Comparison between pre facelift FTO & Evo III arms
And here's some pics of vR vs GPX subframe to see the extra bracing they have.

Hey Pres, any idea what those two little pegs on the Version R subframe are for?

That was a sad day when that happened lol but I'm glad it was only that. FYI that was from massive laterial load [SMILING FACE WITH OPEN MOUTH AND COLD SWEAT]

Re: GPvR LCA Compared to GPX
Thanks Bennoz,
Would there be much of an improvement though with a non-offset bush?
Also, to fit the facelifted LCA, does the car require a facelifted subframe to be fitted?

You'll notice the prefacelift doesn't have them, smartass.

Re: GPvR LCA Compared to GPX
Using offset is purely at your preference. If you have the hole at the bottom of the bush, you'll get max positive castor, put it facing the outside of the car, you get max neg camber, somewhere in the middle you get a bit of both. That's how I set mine up.spetz wrote:Thanks Bennoz,

Facelifted bushes will fit a non facelift subframe, the mounting points are universal.

It should, they both normally have them. I'd say they were removed because of a custom exhaust setup.bjk wrote:You'll notice the prefacelift doesn't have them, smartass.

Re: GPvR LCA Compared to GPX
I actually noticed 2 unused hanger mounting points on mine at the front. So 4 in the same location.

Re: GPvR LCA Compared to GPX
Haha nah I think 2 are on the body and 2 on the subframe. I don't think the subframe ones are used.
