RA23/28/40 and AE71 engine crossmember comparison

[brett_celicacoupe]

yeh sure....


im going to start looking into other characteristics that will be adopted by this xmember soon.

whats the bump steer like?

[TurboRA28]

It's good.. Seat of pants feels great.
If I remember correctly my measurements showed a little bit of toe in on compression.

hey turboRA28
what did your engineer say about the crossmember.
iv got a ke70 crossmember cut up in similar fashion and I’m wondering what problems I might have

cheers Mike

i think i smoke too much crack

[TurboRA28]

Wow this is very interesting! I always just 'assumed' ra40 and ra28 stuff was the same but you are right, they have a wider track.

But.. 320mm you say? As xt130 is 310mm.. 320mm would be much nicer! Is this confirmed?

[o_man_ra23]

Strange, I was also running RA40 LCAs in the 23 the whole time, as I had already changed the bushes in them...I didnt notice any extra track, and certainly didnt have anything resembling -tve camber This was with RA23 struts.

Cheers, Owen

[brett_celicacoupe]

ill double check the LCA lengths this arv

[o_man_ra23]

I will measure my brother's RA23 items when I am down in brissy on sat.

Cheers, Owen

what happened to the RA60 rack you were playing with?

[TA-022]

RA28 bolt spacing 115mm

RA60 bolt spacing 100mm


Sadly engineer ddint like the bracketing to span the gap.

He'd rather i chopped the ends off my std member and welded them to the RA60.


Quite frankly that doesnt seem worth it to me.

I'll go this AE71 for ease and look to retrofit PWR STR later depending on my opinions
of plain RNP.

Yes tis a sad day .... like when Video killed the radio star .... AE71 killed the RA60

Who would have thought it... ???

[TurboRA28]

Brett, mate and luck on ra40 LCA lengths and why RA40 has more track than RA23/8?

[brett_celicacoupe]

im on crack


the LCA i measured the other day probly wasnt a RA40 item. i just measured an ra40 LCA then it seems the same as the AE71.


fucks me whats going on

[o_man_ra23]

I think the RA40s just had more track at the rear, and not more at the front... seeing as the struts are identical to RA23, so are the xmembers, and there is no difference in camber. Will measure the brothers stock setup in all aspects on sats... not just the control arms.

Brett, email them acad files to [email protected] and I will update them with RA23 measurements (if they are different at all) when I get back from brissy.
