CelicaSupra Original manufacturers specs

Hi all
Completing an application to modify my Supra and need a few manuafacturers specs for GA61 which I've been unable to find on the net.
Perhaps those with the knowledge or a CS manual can help?!
Just need to know the original manufacturers wheel track?
I think I can complete the rest myself.
or if anyone wants to provide some links to CS spec pages, I can check on some of my other answers.
ps. The Mk2 Celica should be the same hey? Maybe someone knows that info??
Thanks

Perhaps someone has some details on the RA60?? or MA61? should all be the same...
please help - this is the only question holding back the application

Just get your tape measure out and get a rough estimate. How thoroughly do you think they are going to check the paperwork?

The track will vary as a function of the offset of the rims fitted to each model. I would not necessarily expect a MA61 to be the same as a GA61 or even RA60, given the fact that the rims differ between models.
You should be able to work backwards from MA61 specs, by using track and offset to get distance between wheel mounting surfaces on each axle, then apply the std spec rims for a GA61, as listed on a EPC, to get its track.
Example:
My RA23 has as std, 32mm offset steel rims on a track of 1310mm (rear axle), axle width is 1310 + 32 + 32 = 1374mm.
My 15 x 6 Soarer rims have an offset of 20mm, so the new track with these rims fitted is 1374mm - 20 - 20 = 1334mm, and just by sheer good management, this is only a 24mm increase over std, making it legal here in WA.

Umm, your maths is way out.
If axle with is 1310, then track is 1310 - 32 - 32 = 1246
With +20 rims, you have 12mm more track per side or 1246 + 12 + 12 = 1270
But yes, its still under the 25mm for WA.
Incedently, xA61 Celica XX/Supras came with +27, +20 and +8 rims from factory.
This gives a legal range of +27 to -4 for offsets in WA

I beg to differ....
I have measured a RA23 axle off the car, with straight edges across the wheel mounting faces, and got 1375mm.
I've measured from centre of tread to centre of tread across the rear axle of my RA23 with std rims and original size tyres and come up with 1310mm.
Toyota and Wheels list the rear track of a RA23/28 as 1310mm.
The std steel rims 14 x 5.5 have 32 stamped on them with the size code and I have measured the backspacing at 117mm, meaning that the centre of the rim, is 32mm behind the wheel mounting surface. Behind moves it inboard (from 1374mm, down by 32mm each side, giving the track of 1310mm).
I'm not going to start the negative/positive offset argument again, its about as bad as the chopped springs 'discussions'.
Cheers,
Mitch.

My mistake, I read what I have in bold as one statement.
Ignore my previous post.
Also, on a side note, is axle width mount face to mount face?

No worries. Anyway - we have given enough info for Damo to work out what he needs to know.
And then I might just find tonight that I have an original MA/GA61 brouchure at home somewhere.....
I used 'axle width' as a lazy typist's replacement for 'wheel mounting surface face to wheel mounting surface face' but I doubt that that is the proper technical definition for it. Still, when people use 1410mm for Sprinter and Hilux's and 1380mm for Hiaces etc, it gives some form of comparison.

OK - is it 8mm offset on the 14 x 7 MA61 alloy's ?
Then 'axle widths' are - 1481mm front and 1441mm rear.
Now we just need the offset of the std GA61 rims.

FWIW: And from memory, in the spots where they asked hard questions like this, I just wrote "standard" or similar. They're only interested in what you're modding. I made the mistake of mentioning the factory LSD - and the forms that came back seem to go on about a modified LSD.

I think the word 'factory' or 'stock' came up many many times in my one.
Even my manual conversion I listed as 'factory' as in parts of the world, it was factory.

I don't doubt that writing down 'factory', 'standard' or 'stock' will get you past most inspectors, but speaking from my own experience when I got my RA23 1G-GZE across the pits (successfully) this week, they will only accept factory/stock/std for vehicles that were originally sold in Australia. A GA61 does not qualify for this.
And if you are fitting different rims from stock they will want the original numbers to check the track increase.
Given the axle widths above and steel rims on a GA61 then the tracks are 1427mm front and 1387mm rear.

Woohoo - some knowledgable peoples!! 
Unfortunately, most is over my head  .. not to mention the fact I have no idea what the offset of my Simmons wheels are?!, I'd have to pull them off... or maybe measure them.
Peewee... it might be easier if I come around sometime - maybe this long weekend if you are free at some stage, and we can just measure it instead of guestimating?!...
Let me know if thats ok?...
Then we can post the results for everyone to see!! and anyone else that may be interested 
If they are as thorough as Mitch says, then it could pay to get it all right...
ps. my car was originally fitted with the 15x6 alloy wheels.. I'd use this as the "standard" measurement, as I'm sure it will vary the least?...
Dam.. all this confusion over the wheels when its the engine I'm changing!! I can see this is gonna be just the start of the headaches!
Mitch - is it worth it in the end?? having it all engineered and that to shove in the cops face!

With the 15x6 +20's.
So something is well fucked.
Yes Damo, come over one day this weekend.
We shall measure.

My paperwork took 4 weeks. And yes, mine was pre-conversion.
As part of my inspection this week I spoke to the Vehicle Safety Branch and the bloke there said that these days over 80% of mod approval requests are being sent back because they are incomplete and lacking the requested information.
Surely someone must have an old Wheels magazine with at least the MA61 track spec's in it somewhere....????
And Damo, yes IMHO, its worth it to get every bit of engineering done 100% properly and pofessionally at the time. Cops and Inspectors look at us (vehicle modders) the same way as we look at mechanics we choose to work on our cars. If we look rough and are sloppy with details they will look harder for faults. If you have been thorough and professional and taken care of even the smallest details (like the correct paperwork), they will think you have been like that completely with your car. Whether you have or not only you will know, but you have to drive the thing on public roads, and if you and another member of the public come to grief together it will be you doing the explaining to the judge.....
Its up to you in the end, but to me a car is to be driven, especially one you have poured heart and money into, and a yellow sticker and constant hassles with the cops, defeat that purpose completely.....
Cheers,
Mitch.

I have just checked Wheels and Modern Motor 1984 issues and they both list the same spec's as above for the MA61: 1465mm front, 1425mm rear.

and thanks to everyone else.
Might still head over to Peewee's place to measure up and see what we get.. I still need to check my current track as well as the factory spec anyway..
I'll let you all know the findings...

The 1985 Supra Brochure has tread width as
Front: 1445mm
Rear: 1415mm
Since this is the only one with 15x6's, that is the one to use.
Is tread width the same as track?
Track is centre of tread to centre of tread.
What is tread width?
