MX83 strut/brake upgrade for MA61
|
Mon, 22 March 2004 13:08
|
 |
For anyone who wants 5-stud hubs, bigger brakes and coilovers on their MA61, you might want to look at this little web page I slapped together. Note that this info also applies to RA6x Celica's and of course MX83 Cressida's. Thanks go to John Duel from ImportBitz.com for letting me borrow his struts/brakes for the test-fit!

Keep me posted Norbie, this has got to be the easiest way to upgrade MX73 to 5 stud

Norbs
Do you have an indicative (or even accurate measure for that matter) measurement for the difference in arm length between the 300ZX and R33 calipers ?

norbie - do you have any exact measurement in terms of change in offset?
if the +35 fould the outer edge, would some +40s fix that?

{EDIT} : Are the ones that suit an AE86 anywhere near similar ?
|
I'm pretty sure that the bolt spacing on the tops differs by something like 5mm between MA61/RA65 etc and AE86 and MX62 for that matter  ).

So the intention is to fit these to a MA61 strut???

Nope, the plan is to replace the MA61 struts with MX83 ones 
(doh for me as well because I also have MA61, well SA63 struts with supra springs in my car )

Hi Norbie,
Thanks for the info! Do you know if the new brakes will fit under a stock MX83 Cressida 15 inch rim?
How much do R33 calipers go for at the moment?

I never tried fitting anything smaller than a 17" rim over this combo, but I suspect you'll need at least a 16" rim.
Not sure about R33 calipers, I'm still trying to find a pair myself!

Very unlikely.
I am using a 326mm disc and 300ZX calipers, and with 3 piece Simmons rims, there is less than 5mm clearance, so with std cats mags, 16" might also not make it over the Faclon/Skyline brake combo.
Justen GT4 got a set of R33 Calipers for his project, contact him for where he got them from

Since Norbie showed me this a few days ago I have been looking at finding all the components and getting prices..
I found a set of struts for Norbie in BNE for about $75 each.
(Did you buy them Norbie ??)
R33 GTSt Calipers are going for anywhere between $250 and $395 a pair depending on where you call. Some wreckers offer warranty, others won't and that is reflected in the pricing. I've found a few sets in my calls, but just waiting on response from a few more places before I decide where to buy from...
(Make a few calls, there are quite a few places with them in stock...)
BA Falcon Rotors "New" are about $115 each
BA Falcon Pads "New" are from about $50 to $135 a set.
So for an MX83 Cressida - the whole package can be had for under $550. - BARGAIN !!!!!

Southo,
You'll need 300ZX/Skyline pads, not the BA Palcon ones. Make sure you get a decent compound though. Don't skimp on brakes.
Regardless of the price that you pay for the calipers, get an overhaul kit. It is only $30.
Don't forget to add in new brake lines, and remeber that for an MA61, the spring perch needs to be altered, and also the shocks are different. If only $550 was it ....

OOps, my bad re the pads - Not thinking properly..
I paid $120 for EBC Greens for my R32 GT-R about 3 years ago, so allow for inflation etc - they are probably closer to $200 a pair... Anyone priced/bought any recently ??
The $395 price I quoted was from a brake specialist who supplies them overhauled with 12 mths Warranty...
Braided lines are about $75 from Pittwater Brake and Clutch...
OK, revise my estimate - make that about $900....  (for a Cressida.....
|
The best price I could get for the EBC Greens was $250.
IMO, braided lines on a street car are a waste of money. Yes they are better, but you have to have everything else up to scratch, have good tyres and race cars. On the track they are worth it, but for the road, spend the money on other things.
$395 for a pair of overhauled calipers. Shit that's cheap. When looking for the 300ZX calipers here in Adelaide, some want $300 PER CALIPER AS IS !!!!!!

Another option if you need to stick to 15's is AUII or AUIII rotors, identical except smaller diameter (287mm). May work with the R32 calipers if they don't sit out as far. Minor machining of the disc may still be required. This is the option I will be looking at as 16 inch rally tyres are hard to find.

Out of interest, how far apart are the holes at the bottom??
Do you need to get RCAs, i guess roll centres would drop by similar amounts, but you'd still get a decent amount of bump steer if you went low enough.

I *think* the IS200 is 5x100, sure I saw pics of the wheels on an MR2. Bit of a bugger, can someone confirm?

According to the good book, they are 5 x 114.3, but the offset is +50mm, which is pretty high and may cause problems with caliper clearance unless a spacer is used which then brings in other hassles ......

this wouldnt work on the rears as well would it?(using mx83 rear struts?)
also, not that i can or will likely ever be able to afford them, but are JZX90\100 coilovers similar\identicle to JZX81?

Neither the MX83 nor the MA61 have rear struts; they have double-wishbone IRS and trailing arm IRS respectively. Needless to say the suspension components are in no way interchangeable!
I don't know much about the JZX90/100 but I suspect they have double wishbone front suspension.

as soon as i posted that i realised the error in it and tried to edit it, but it wouldnt let me :/ kept saying there was a problem
i always keep thinking i should put more thought into most of my posts...maybe one day i will
the reason i asked about JZX interchangability is because i got bored at tafe and tried looking for JZX81 coilovers and could only find JZX90\100...

Cheers Southo. It's amazing how much they can vary. I sourced some 2 pot rear 300ZX calipers for $200, and some places wanted $200 EACH !!!!
Keep us posted on your conversion
Norbs,
I guess there is one bit to be machined, and that is a 'donut' that locates the disc centrally on the hub, as the hole in the BA disc is bigger than that of the Cressida ? Is this correct - pretty easy to do anyway

When I bought my rims I explained I was doing a brake conversion and he asked what rotors/stud pattern etc so he could get me the right offset and ring locator until the brakes were done.
At that time I was going with 330mm C'dore Rotors and Calipers..
The Cressida Rotors are has a 60mm Centre hole whereas bother the Commodore and Falcon ones are 71.5mm - so my current 17x7 "commodore" wheels will still fit without any drama..
.
The factory Cressida alloys probably will not fit now...
The total rotor hat height is 3mm difference out - Cressida is 68mm, Falcon is 65mm..
Soo, of I have worked this out correctly.. The Caliper will sit about 3mm closer to the wheel spokes, the ring locators (on the front at least) can be tossed away.
As for the rears.. Apparently the US Cressidas got Vented rear rotors from the JZX81 ????

Nah,
The 'donut ring' I was referring to was to locate the disc onto the hub centrally.
Depending on the rim used, you may need a similar thing to ensure that the wheel is located centrally on the hub.
Hope that make sense

Ahhh, Ok, I know what you mean now...
BTW, I forgot to mention that the place I bought my Calipers from for $110 each was RMA Spares (Southport) in QLD.. (07 5532 7914)
They are certainly the cheapest place so far and the staff there (Steve / Rod) were very easy to deal with and got back to me when they said they would.

Most definitely. The going price is about $250 (from several places). You can find out the pad no from the ebc website.
I was going to look at either Ferodo DS2500/DS3000 (the latter for track work) for my application.
I haven't got pads yet myself, but will wait till I need them at the last minute

Yikes !!!!
I paid $30 for the caliper overhaul kits. This included 8 dust seals, 8 piston seals, 8 metal rings to hold the dust seals in, and a wee bit of rubber grease. This does BOTH calipers !!!!
What else did you get in the $145 kit ?????????????

So far....
Calipers $220.00 (Nissan GTS25t Factory)
Rotors - $320.00 (DBA 4000 series slotted)
Pads - - $ 80.00 (Bendix Ultimates)
Just waiting on finding a cheaper caliper overhaul kit ( best is about $145.00 so far..) - looks like genuine is the ONLY way to go, although I was chatting to a mate who owns A brake / clutch specialists workshop and he seems confident he will be able to overhaul them cheaper than that once he takes some measurements...
I'll keep you posted..

If anyone is interested in a pair of R32 OR R33 calipers, I'm selling mine.

Yep,
I have the MS123 rear stubs now residing in the MA61 contril arms. All I need to do now is to fit them to the car and jigger around with the brake shoes to make them fit the new discs
Norbs, how come you are selling both of your calipers ? Got something even better in the wings ......

John Duel is selling his complete setup (ie the gear I was test-fitting at the beginning of this post) so to save myself the hassle of chasing down struts etc I'm just going to buy it all and be done with it. That means the calipers I already bought are redundant, so out they go!
As for the price, I'm asking $220 for each pair.
