corsa b coilovers to fit micra ( HOW TOO )

The other day i got the first few mods on the front of my corsa b coilovers.

today i got the most pics i could to explain in simple terms how to do it, this is what i done first.

first i tied up the micra spring to take the tension of the spring why i buzzed the top nut off.

then i took pics of the micra componants you will need to keep.

the micra top suspension mount, the bit that sticks up try to follow the same mesurements.

the steering washer that makes the suspension leg turn, you will need this.

as for the corsa b leg it self the holes were pretty close as you can see.

the top camber hole i drilled out centre to the bottom hole.

as for the micra top cup i forgot to drill that out, so tomorrow i will get it drilled and load pics of the legs all assembled together :p

that nylon thrust washer might be a bit short lived eh nippy :eek: on karls we used both cups iirc

when i looked at it i thought that, but i have had 2 opinions and they both said it should be fine, i was thinkin of getting a washer welded on to the top cup mount just so it sat the hole of the washer on but i still might do, but i will look more into it thatnk you for pointing it out (Y)

Hmm i will look into it more, do you have pics of what you done mate?

we fitted the corsa cup under the micra one nippy (else the nylon thrust bearing is,nt supported and will probably collapse under the weight of the car )

i see what you mean, how was both cups supported tho, or was they just sitting freely?

I think I might be inclined to trim the micra top mount down along the green line. In the pic it looks a little bit like the shaped section that forms the spring seat would prevent it from sitting right.

You have a lathe though so why not turn up a thick washer the correct diameter to suit the shaft and the thrust washer.

i had a think to see how i could get the thrust washer sitting nice, a little mess on windows paint and i came up with this.

it dont sit full frank, as i had it lathed down :down:

and i was thinkin of cutting the top off just to use it as a big washer mark (Y)

Is it not possible to lathe the spring cup more until the thrustwasher sits completely on it?

not really mate as its been lathed down pretty far as it is, any more and it might go through, but there is only about 2mm hanging over the sides, not much really, i have seen on a blog on the net, of a k10 micra that dint lathe his down at first and was running with the thrust washer hanging over pretty far the pics i done on paint, if i lathe down abit more nearer to the edge and get a alloy washer lathed up and taked in place just for the thrust washer to sit on should work

had another day with the coilovers today, so i took the top cup mount to my dads good friend, to see what he can do with the top cup to try and get the thrust washer seating abit better, also asked him to drill the top leg mount, and to file down the metal bush thing on the corsa rear shock, but today i had a little problem! i snaped a bolt :doh: trying to take the right hand rear shocker off.

clean SNAP :down:
Photo0173.jpg


not to worry tho as the bolts that hold the front legs on fit FTW!!! :laugh: and they fit alot better i think :wasntme:
Photo0174.jpg


i got bored after and done this.
Photo0175.jpg

Photo0176.jpg


i tryed the corsa b springs in with no shockers, just to get a look at what she would look like laying down :laugh:
clearly the springs dont fit.

Photo0180.jpg

Photo0177.jpg

Photo0178.jpg

Photo0179.jpg



But monday i pick my bits up from me dads good friend, then they will be all done, apart from cut springs, that should'nt be a problem tho grr

also with my car living its life on the north east coast, its rotten, so the nuts holding the panhard rod on, are fooooked, any tips on how to get them off with not another SNAP!

this may help. after a few days i got some bang up noises . dont know if it was up or down stroke on the front left suspension,
fiddled with it a few days then eventually thought to cut the sleeve down a bit, then thought naa first add 5mm to the 3.4 mm as cannot add once cut. now its gone back perfect. the problem was the spring cup spoilin on where the sleeve meets the bottom seating. must have cleared it now, smooth smooth all the way now better deal with balljoints/cv'joins what not

self centering ,,,,,,,,

centralized by top nut hole being caressed by franks circular file

the assembly, no helper springs.

where it was catching the top spring holder

where to weld
DSC02367.jpg


sleeve size , i would go for 3.9 mm to clear any trouble :grinning:
DSC02374.jpg


pipe i used to add 5 mm length, place at the very top after sleeve. gonna need a one piece as soon as,,,,,,,,,

job done ftw :grinning:

I used m12 washers instead of 1 long spacer, worked out well for me.

Can you use cable/zip ties to secure the brake hose to the strut, and pass mot, as all it needs to be is 'secure' isn't it?
And what's the benefit of removing the helper springs?

maybe , if the hose was held securely enough
whats the helper spring actualy helping? and where you put em top or bottom end

top mount holes on shocks need widening in a slightly downwards direcion
need a sleeve to fit over this

DSC02389.jpg


thickness of sleeve support, idealy have the sleeve that thickness

DSC02396.jpg


a round file to allow it through the top mount , not much fileing to do realy

DSC02382.jpg


brake line bracket
DSC02367.jpg


where the thread starts,

DSC02405.jpg


thats the minimum size you can have the sleeve - car at its lowest.
other than that you can have as many different sleeve sizez for the height you
choose due to rims/tyres, butinvolves removing the whole leg again and again and isnt
much height diference, this ones for the low i guess
dooable though so not a big pain.

this is what i missed putin in so was getting knock noises now and then

DSC02414.jpg

DSC02415.jpg


spring on - sleeve on
these here on
DSC02418.jpg


tighten top nut down, do spring up by hand first, lock it and adjust later if you want it a harder ride

camber adjust, flat screwdriver marked up

DSC02353.jpg


and just follow the pics realy ,using parts from your old micra leg

DSC02371.jpg



notice diferent springs on karls ( project charlie ) ones maybe why his has sag'd or
sumpthing but springs are gettable, these things rust big time the spring and body, is why i
hit em with some bitumin type paint that hardens slightly

DSC02411.jpg

DSC02422.jpg


the rides very decent , smooth like-- member malcolmt said it reminds him of the mini's when he had a ride

thanks to other members for taking the plunge on this one you know who you are, made it a posibility for me

the sleeve is like below he has used washers to bring it up to where the thread starts

No Issues

Hi all, Really do not see the problem with fitting these, either that or we must have a different corsa b kit to you lot, we have fitted two of these kits now and used the whole kit inc rear shocks and springs, When you get it all apart it all becomes clear.

Also the only issue we had was trying to use the plastic nissan top bearings on the front strut as these were binding up and every time you turn the steering it was trying to undo the top nut, you do not need these as the coilover comes with a bearing.

Once you have it all together on one side get a mate to turn the steering wheel and make sure it is not undoing the top nut, if it looks like it is then you have done it wrong.

pic of the bearing'd be handy
 
Shows how much you know then will930. both our micras have them fitted and both have been through an mot, but hey what do we know we are only a tuning/modding company.
We don't supply fitting instructions and walk through fitting guides as if you can't work it out and it is quite easy then we feel it would be a danger to show people with limited mechanical knowledge. Sorry. but safety comes first.

of course safety comnes first im not dumb! but i know for a face that the corsa rear springs are egg shaped type and the micra ones are stright and uniform

with different sizes at the ends that would cause seating issues from the start otherwise other people would be using them without cutting std springs
 
Similar but not exactly, also i'm not sure if i read it right but are people using corsa b top mounts? we are still using just the original nissan ones all be it brand new to make it all new. (another bit of information extracted from me lol) :glare:
 
i didn't say you are Dumb i just said we have used em and they have both gone through an M.O.T no problem. They are egg shaped but they can be made to fit really easily and by doing this you have a matched ride and height. and i must say and we use a road kit not a race kit the ride is superb.
