Q's on 5 stud conversion

hi guys
im thinking about a 5 stud conversion for my ra40 celica,
1)would any one have any ideas on where to start or what are possible avenues
2)which cars have the same suspension arm mounts as the ra40 (the bit that bolts onto the cross member)

if you're going to all the effort of buying (what's priced as gold-plated) hubs, you may as well improve the brakes and you'll need different front stuts (e.g. XT130 or RT142)

That camber will be all kinds of wrong in an RA40. You could make it work though.

What about those RA65 jobbies? Didn't they make 50 kinds of goodness (or was that just in the MA61)?

Umm interesting.
I was going to go the RX7 calliper route with a custom bracket but do i read this correct?
rt142 strut, ms65 hub, BA rotor, probably a little ring thing from GT to space the rotor and wheel correctly, and r33 4 piston caliper will make an upgrade without a custom bracket?

wrong camber with an RA40???
although if you tried the AE86 rack and pinion steering that Turbora28 has done which apparently increases the track slighlty, this might negate the camber (possibly more so with adjustable camber tops).
Hmmmmm
must go visit wreckers and take a tape measure with me.

i'll have to find my pics that compare stub axles of MA61 and RT142 - but visually it looked slightly better (e.g. more -Ve camber).
On an RA40 i think it might end up the same as stock (whereas the MA61 would give you positive camber if fitted to RA40)
note: this is only from eyeballing it - have been too busy to bother photoshopping pics of struts.
as for Rotor fitting - damn good question - i know that an old comondoor (VL i think - they all look like same shitmobiles to me) rotor+hub thing fitted very snug, tho you'd defiantely have to mount you caliper from the back of the caliper mounts.
what kind of rotor were you expecting to use (i dont have any MS65 hubs  )

i have MS65 ones here, i payed i think $28 for 
MX83 ones an option???

i am having heaps of fun ATM picking the MS65 hubs out of 20 various model crown hubs (removing outer bearing one by one )
i might be able to park my RA40 next to a MX83 and compare if anyone really wants comparisons. slim chance it will be ~perfectly~ suited to the job without some sort of modding.
it would be good however to find a strut with a thicker stub axle than the RA40/MX62/MA61 etc because there are a shitload of hubs that use the "bigger" bearings. (like MS85/falcodore etc.)
come to think of it; allan, you have mkI supra bits?? what bearings do they run? bigger or smaller than RA40/MA61 etc.?
this is what cruzida posted a while back....i just noticed he didnt include the MA45....makes me wonder

same as ra40, maybe different as per ra60 vs ma61 due to wider track.

Was the MA45/6/7 ever released here?
The MZ10/11/12 is not on that list either, but thats not a locally delivered car, so thats why.

MX83 doesn't use single-row tapered bearings - stub axle has no tapered sections, bearing bits are all in the hub and it uses two 'rows' of uncaptive ball-bearings that roll directly on the stub axle.
If it weren't for the steering arm issue and poor camber, they'd make a good bolt-in replacement strut.
note: the MZ10/11 etc are 4-stud, they also use the same wheel bearings as ra40 et al.
as for MS65 hubs, so far the best price i've seen is $100 (offered by PM) - before i pay that much for one set, Wilbo & I are checking if other cars of the same era (circa 1972) use the same wheel bearing sets.
cheers,
Charles.

RA60 power steering arms might work??, they are super duper short too.
what type of camber does it give? how much + ?

Check Norbie's site and have a quiet chuckle at the inital gay appearance of his car after he put in the MX83 struts. There was about 11ty billion degrees of positive camber. Like he said, all kinds of wrong.v
|
yep, norbie's setup does give you access to new adn interesting suspension hardware, but the cost of fixing the camber and steering arm issues is (for my budget) excessive
| Quote: |
Also you guys should be checking old Dattos, like 260C and similar. Hilux 2WD and Hiace also good to check too.
|
yep.. have been doing that... results so far has been less than satisfactory.
data gathered to date: <http://members.optushome.com.au/mkhala/bearing_dat a1.rtf>
future searching will focus on cars released around the time of the MS65.

As wrong as the above is, you'd actually have more positive camber on an RA40. Fixable with bending etc, but as above, not cheap.

Yep, as thechuckster said; been exploring that, with not a whole amount of love yet 260z's share the same bearings, but not 5 stud. Apparently 260c = no go either.
A think to mention about norbies is his wheel offset pics. He has quite a bit of wheel / strut room to play with this his 17x8's +25's...I was going to look into the possibility of using rims with a higher offset (+35's; same rim dimensions) and a slightly longer lower control arm to try and get an acceptable arrangement...Norbie, car to comment on the possibility?!
Obviously the idea is to use the longer LCA to get camber back to normal, and the higher wheel offset to get the wheel back inside the guard. Not sure if 10-20mm will be enough however, which is what I will look into.
Cheers
Wilbo

1. My tyres only just clear the outer edge of the guards, and that's only because of the camber I dialled in, so you've got no wiggle room there.
2. There isn't much tyre->strut clearance with 235 tyres... you might be OK with 10mm but I don't think you could go much further.
