S13 suspension (front and rear) into MZ11/Ma61 *LCA'S???*

[slipway NZ]

Yea i thought about going for 2nd hand stuff but TBH, most of the stuff would have beed drifted thrashed an due for a rebuild, thats expensive.

so you can pick up sets of 2 step adjustable ones for 12-1400? over here anyway, and you know there gana work.

But yea building them from strach is hell expensive

o.k,

Seem to have the suspension sorted now,
brought a full set of BC racing s13 coilovers, the botoom brackets are made of steel, sooo
I will cut the s13 brackets of so im left with a steel threaded tube, so no longer need to have one made from scratch.

The bc bracket is very very close to sliding over the std strut tube, so i will take it down to the exaust shop and get it expanded about 1mm so it is a very close fit, and just hammer it on.

The rears maybe slghtly more tricky, the bottom EYE hole on the s13 shock is larger than the toyota one, so ill either get a bush that fits,get one turned up, or turn up a sleve that will fit on the bottom shock mount(once heated) and then will mount the s13 coil on there, the top is also tricky, i will prolly end up custom making a upper mount with some 4" tubing and drill it to suit the s13 bolt pattern.

fronts will be done like this, but will make it tidyer.

The botoom mount will also need to be re inforced so it can handle the spring preload.

thats a pretty good idea of what your going with. i think i might tread that path as well slipaway. ive jsut won a set of kai office coilovers myself

can you get poly bushing whith out holes it them, or more so the material so you can turn it up your self?

i think when i do mine i might add an extra peice of tubing at the bottom in between the strut bottom and the steel threaded tube so you can drop the strut body jsut that little bit lower down & also so that you can jsut cut the strut if you want to run them on a different car also without damaging the strut bottom and steel threaded tube.

update...

put the s13 hubs with kai office coilovers in tonight and found out they will be at max. 100mm shorter than std. strut set up... the LCA is about 15 deg. from horizontal in the air and the wheel looks about 3 inch from the bottom of the fender arch... if that gives you an idea.

is 100mm shorter to much for a mz10 set up?

also i got some s13 tie rod ends, but im unsure what rack ends i need... the mz11 tir rod ends are about 160mm long from center of the ball joint to the end and the s13 is only 100mm thats about 60 mm i need to bridge...

ra40's? mx71's? not sure?

[japlish]

i THINK the mx73 guys on jzxproject.com use ma70 inner rods?

[Negative Boost]

I thought you could use old Bluebird inner rack ends i think. But that may of been for the Sigma arm conversion.

[The Real Roadrunner]

try corolla rack ends ea92 i think. they are 14mm and screw straight in to the s13 tie rod ends. may need to be shortened but unsure. i use these when doing s14 frontends in 86's

[Johnzoku]

thanks guys for the sugestions, i think ill jsut take my old ones down to the shop with the s13 tie rods and see what they got that will bridge the gap...

my main concern now tho. is the angle of the lca its almost horizontal so obvously i think its a bit of a problem atm. and is the main factor of this working or not.

ill have to take some good pics of the set up togeather but ive got my two way hight adj. kai office coilovers and ive screwed the strut about 20mm up from the bottom of the base of the coilover and the spring perch screwed about 50mm from the top... which makes about 550mm (hub to top of camber plate)

has anyone on here droped there soarer 100mm odd?

heres a doggy pic... on up side is i dont think postive camber is a problem with this set up... i measuered the hub lengths between the two and its 10mm shorter on the s13 hub.


notice lca...

[japlish]

i think my lca's are almost horizontal as well and it seems ok.
the outer rack-ends even angle upwards.....

[Johnzoku]

but is that when its in the air? if so ill be sweet then... i jsut need some c spanners to sort this out properly.

thanks japlish.

[Johnzoku]

hate waiting on parts! heres some better pics, it looks the good to me jsut have to redrill the strut top and im done.

[japlish]

yeah that looks like it'll be ok.....just

[Johnzoku]

finished my suspension up grade.

as follows.

S13 kai office height and spring adj. with 9kg springs on front.
S13 kai office camber tops, Mz11 redrilled to suit.
S13 stub axles
SR20det brakes and disks
R31 tie rod ends (14mm thread)
MZ10 272mm long rack ends (14mm thread) - RE879 (SV11, MA70, MA71)
S13 strut bar
all sitting on Orginal MZ11 LCA's with orginial ball joint.

positives
*biger brakes
*cheeper coilovers than custom ones
*can still use orginal LCA's
*more lock

negatives.
*due to the design of the S13 gear you lose about a MAX. 10mm each side of track.
the next step from here might be trying MX62 LCA's or even S13 LCA'a
*the max negative camber you would be able to get would be abount -2.0 before changing LCA's
*i'd make sure you get two height adjustable coilovers, makes things easyer altho they can be slightly more expensive
cant use under 15" rims and cant use stock soarer rims either.

problems.
*the kai office camber plate studs were wwwaaaayyyy to long to fit when the bonnet was down so i changed them to the orginal ones of the soarer.
*with the brake lines, i read a few ae86 -s13 coilover threads that said using the stock S13 lines would be fine... but when i used them i found that you couldnt get enough thread it to them (say 4 to 5mm...) so i got some new ones made up where the line going from the hard line to the strut was the same only about 2.5" longer and the line going from the strut to the brakes had a banyo joint on the end rather than the stock screw in type on the mz.

TOTAL COASTS
S13 stub axles with sr20det brakes and disks (pair) - $300
disks machined (pair) - $40
new pads - $40... ferado... pov spec.
rack ends (i needed new ones anyway, might be able to get away with your orginal ones if there 272 long) - $50
R31 rack ends - $50
S13 strut bar - $100
brake lines (again needed new ones anyway) - $80
and finally Kai Office coilovers 2nd hand off yahoo auctions - $330

TOTAL - say $1000

So in the end it could of been cheeper to convert mz11 struts to coilover but when you consider, the cheepest coilover tops i could get were about $250, $400ish for some adjustable TRD 4way shocks and then getting some threaded sleves, top hats, springs and getting someone to do it for me as well... say $300 - $400ish. = $950min.at leased for a bog standard set up.

for a $1000 i got a better choice or coilovers, bigger brakes, and if need be going from sr20det brakes to larger brakes shouldnt be to much hassle (i.e. S15 R33 i guess?)
and for someting that had been done just a few times in ae86's i didnt see why it couldnt be done in a mz soarer or ma61 etc, i havent seen many ppl tread that path yet so i hope this might help ppl out.

[The Real Roadrunner]

have you checked how much bumpsteer it will give you?
is there enough droop with the s13 coilovers (70mm min) or would it have been better to use s14 as there about 35mm longer?

cheers
linden

[pisso001]

Sorry if you covered it earlier but whats the length of your Stock LCAs Ive got MX62 LCAs in my corona and they are a little too long.. Also when you have it on max height how low is it? I found it too low with the S13 coilovers and like linden said not enough droop.. Im now looking to fix that some how, probably S14 coilovers...

Thanks,

Chris.
