First off cheers for the help lads

Myne - thanks for the info, but its already a bit of a weird mix - i'm looking to upgrade to ~260mm discs, which will be a mission in itself - so i'd prefer not to make it any harder than it needs to be

Thechuckster - any measurements i can take, more photos to very any theories?

oldcorollas - They appear to be 10mm thick

Diameter i'm just trying to come up with a good way to measure, any suggestions?

The spring diameter is visibly smaller than the ke25 stockies (assuming they're the same as ke20) - but it also looks to me like the bottom spring seat has been hammered a little to help things sit a bit tighter?

To set the scene, i believe a ta22 donor car was used in setting up my car - engine, box, diff, are all from a ta22. I'd lean toward most parts being used from a ta22 for this reason, but you never know..

ed: Oh, and is it just me, or is that a weld half way along the lower arm (forgive me, don't know the correct names for most things like this, feel free to enlighten me) - and is this usually present, or is it something someone has done to make this all fit?

ahh k, forget about my dodgy KE70 theory i guess in theory it is possible to have bits welded, but i can't check the code of practice atm (it's not close), but it would have to be signed off by engineer... even welding cross-member is not taken lightly.. what you cannot do is to weld cast iron parts or steering components.. under almost any circumstance (unless it is done very very porperly and tested to be safe) there are a few different LCA's out there, incluiding the smegma arm into AE86 stuff, so there may be a non-bodge version around... tape meaure, calipers and wrecking yard ... it does look like TA22 gear... the KE20 ball joint is pretty small (but bigger than KE20), but you'd have to check the spline size, and measure the diameter of where the BJ goes into the arm to be sure...

The last paragraph here - i assume you meant to say the ta22 ball joint is pretty small (but bigger than ke20)?. I'm not familar with where you want me to measure, and like i said i'm not good on the terms for most of the parts, let alone the acronyms


Tricky - thanks champ, i'll do a search. Are we working on the fact that what i have now is a ta22 strut, or that it doesn't matter and that an RA23 one will fit anyway? Sizewise 254mm isn't too bad a size, but i was hoping for vented rather than solid.. For the record, the r31 brakes are 260mm or so though, so the fronts will be a tad smaller in this case. If its an easy option though, this isn't so bad. Having good calipers should make up for it..

Mrshin - I've already bought some 15" wheels that i was planning on using (the s4 calipers may object to this though...), so this rules out anything much above 260-270mm i believe (depending on caliper). I've measured the internal diameter of my wheel at 335mm at its smallest point close to the hub, and 365mm further out from the hub. I might have to accept a change of wheels because of caliper dramas, but i really don't want bigger than 15" particularly.

I noticed the handbrake deal on the r31 rear. I've dealt with these on my old ED falcon daily and it was a real prick..

For the record, everything on my car now is engineered. That includes a 6pt roll cage though, so take that with a grain of salt i suppose...

OT question - when i go to have the ca18det / new brakes / diff etc inspected, can they knock back the engineers report on these items only if they don't like my roll cage?

ed: Can an ra60 vented disc be used on an ra40 strut?

When i've searched in the past, haven't found people with ta22's doing the corona/pug/hilux deal, most people seem to do all sorts of different stuff, and have headaches in the process..

Will i have any dramas in terms of strut tops, or is it a given that they will be fine?

The $300 i could get for these s4 rx7 calipers would also go a way toward getting parts for the other gear.. Or $300 off my credit card... Or paying for the $300 ca18det i should have this week or next...

ed: The xt130 deal also gives me the satisfaction of doing most if not all of it myself, which is a big plus, rather learn something in the process

So the later Ta22s had the correct size stub axle? My engineers papers say my brakes and running gear are from a celica circa 74, but worth double checking of course.

As far as upgrading to ra23/40 stuff goes, i'd be all for it if they were vented, i want something in the order of 260mm and vented - not going to have an intermediate "yeah that'll do" sorta setup. Aside from being solid, the ra23/40 stuff would probably be fine, shame... I guess i'll have to make the call on how much i want to spend, IF they aren't suited to pug/hilux/corona.

By stub axle size, you mean length or diameter (or am i picturing the wrong thing completely ). (Ed: and what size am i looking for?)

The car is currently fully engineered as i said, i should add also registered, exactly in this condition in march. Not to say that my inspection was particularly strict, mind.. If it causes a problem later on i'm sure something can be arranged without the use of that weld.
