Nm35 Bc Br Coilover Setup

[Daleo]

Ok, due to the number of people fitting these at the moment; I thought I'd supply my rough adjustment numbers for initial set up.

These numbers won't be ideal for everyone, but the aim is to have a ballpark setting to speed up the fitting process, as the fronts come set extremely low, and the rears rather high. You can then fine tune heights to suit your preference, or even go to corner weighting to acheive a perfect setup.

Front;

Free length of coilover assembly; 387mm from underside of top mount plate, to shoulder of lower mount (the part that makes contact with the forged mounting arm)

Spring length; 195mm from underside of top mount plate to upper spring collar (the part of the collar in contact with the spring and plastic washer)

This will give an approximate guard to hub centre measurement of 360mm

Rear;

Spring perch height; 45mm from the widest dia. of the machined perch to the outer spring collar (the part of the collar in contact with the spring and plastic washer)

The spring perch faces down; so the measurement will be taken from the highest part of the shoulder to the lowest flat surface of the lower spring collar.

You will still be using the rubber bumper from the spring cup in the lower control arm.

This will give an approximate guard to hub centre measurement of 360mm

The reason I haven't included ground clearance measurements is depending on rim diameter, tyre profile, and bodywork heights; these measurements will vary wildly if you're running 17x7s with 215/5517, versus someone running 19x9.5s with 265/35/19 and so on.

My car doesn't scrape on very much at all and with 245/45/18's on 18x8 V35 rims; has about a 12mm gap between guard & tyre when looking in from the side of the car; which is about spot on for my eye.

Have fun guys, and feel free to add any measurements and set up tips for others to benefit from.

Cheers, Dale.

dont forget to mention those measurements are on an RS/RX model. ARX will be differernt in distance to guard

Good point Iain.

I reckon they would still be fairly decent as a starting point as they are neither excessively low, nor particularly high.

[zei20l]

the ARX is way too high to begin with

good writeup mate!

[Daleo]

Posted in the "Awesome" forum too.

I didn't think anyone had fitted these to an ARX yet, would it be possible?

YES!!!

I wouldn't mind dropping it around 30mm all round (not too crazy)

[WAGON_BOY]

the other difference is i know i run a different diametre trye on the AXIS........ its smaller than the rest dunno why but yeah!

once i get my hands on mine ill post up results according to Dale's handy notes....... thanks again Dale

Mounting points are all the same, so there's no reason why not.

Possibly the only reason manufacturers wouldn't recommend, is because you may not be able to match standard height if you wanted to go that way.

30mm below standard AR-X height would be fairly straightforward though.

so far i have only put the fronts in but im sitting at around 352ish from the guard to hub centre,

i'll see how i go with the rears tomorrow and take it for a test drive but i think im gonna have to raise it a bit

Lol, that's pretty low , probably looks sweet tho', so the measurements didn't work for you Theo?

Edit; how far down over the metal guards do your plastic overfenders extend?

Also, are you running 225/45/18s or 245/45/18 on yours?

ok the front measurements worked for me but the rear was a pr!ck........ rear plate was 25mm not 45mm and i wound the shock all the way to the bottom and i think it was still a little to long........

but now its sitting 360mm all round

yep

Missus bought me some. fronts are in and the rears today

What a good girl!

Is she making sammiches to keep your energy up whilst working?

[Sunkist]

lol im the cook of our relationship.

she hated how bumpy the car was so she went and got them lol

[iamhe77]

Do you have one of those internet fridges Aaron?

[Sunkist]

dont get.aa

[Sunkist]

and the rears went it.

but they will need a 3mm thick washer to also go in between the fork as there is a bit of movement. once we pulled it apart and did that it all went perfect.

fronts are set up exactly as i want, but il need to raise the front a bit, fairly low out of the box

Absolutely right Aaron, I've posted that a number of times in other BC related install queries; that and the rear OEM top mounts needing to be re-used.

Probably should've put it in here; but it was more of a set up guide than an install guide. I've sent a bunch of PMs with more detail to those who've asked. I might have to cut/paste one of my PM "how to" guides into this thread so the info is all in the same place.

Get used to the improvement over stock that these provide; then (gratuitous self promotion) maybe point your GF to some Swaybars? After all; power is nothing without control...

lol nah she spent $1k on me i think thats enough.

ill do sway bars eventually but as ive made a dramatic improvement over the previous suspension ive had, i think ill just get used to these first..
