Nismo Coil Springs

[Bis-e Bee]

I was crawling around underneath the M35 having a bit of a sticky beak at what's at the back and found some nice red coil springs.

Upon closer inspection they are a Nismo product, they had 55320-RSM55 on them.

Can anyone shed any light on the specifications of these springs?

couldnt find anything, but there are calc's on the net if you can be arsed measuring them!

Bugger, I thought the product code might have shed some light on them.

Anyway, picture attached

If anyone else has these springs or can shed some light on them, let me know.

i have the same in my m35, they are Nismo S tune

you should also have matching s tune struts painted in gold with nismo stickers on it

they are a street orientated sus package, 20mm lower and stiffer then stock, but not track hard

my car came with full service history and documents so i should be able to take a pic of the sus paper work

hope you can read jap

Ross,

Thanks for that man, much appreciated.

I don't read jap but have saved the pics for one day when I run into someone who does

The leading product numbers are slightly different, mine 55320 yours 54010 but look very similar.

I havn't been able to get under the front end to find the suspension but I will when I get it on a hoist.

It sits quiet well and handles great so chances are it is a full nismo s-tune similar to yours.

Once again, thanks mate!

they pic i attached is of the front sus, the rear coil would have a different part number since its seperate from the strut assembly

id hazard a guess its the same set up as i have.

D'oh, silly me, I did work out that was the front strut but I havn't got under there yet as there is not much clearance and a million things to see when you do look under there.

I can't wait to see under the front and find out if the nismo gear is there too

[Ross]

just take a wheel off can access it it far easier then trying to slide under the chassis

I'll have a look in my Nismo Catalogue sometime today & post the spring rates.

I have a set of nismo shocks installed in my S1. I got them second hand and they were recond with new valves by a local Bilstein trained specialist. They are Bilsteins presumably made to order for Nismo and stamped "Nismo". Mine are front:

56110-RSC45 ENP and rear 53210 RSC45 ENP. My springs are Teins front F-SIN78-010311 HCC and rear R-SIN79-010382 HCC

Jelousy is such a curse!!

I'll go searching for more goodies later today and will email you personally to tell you about them

Nah, I don't think there is much more in the goodies department but there is so much to check out underneath and in the engine bay etc.

Yep, 20mm lower.

Spring Rates;

Front: 8.3kg/mm

Rear: 9.2kg/mm

They are a beautiful ride aren't they

[BensDR30]

OK,

According to my 2003 Nismo catalogue, the following is the full S-Tune kit for the M35 (4WD)

5300S-RSM55

It then has a parts breakdown as follows:

530FS-RSM55-R (FR Assembly)

530FS-RSM55-L (FL Assembly)

56210-RSM55 (rear shock)

55020-RSM55 (rear spring)

The specs for the springs are:

F: 8.3kgf/mm -20mm

R: 9.2kgf/mm -20mm

Hope this helps.

LOL

Thanks guys, sheds some light on it.

Although Ben's codes vary a bit to what my springs have them (55320-RSM55).

They looks like S-Tune's tho, and they handle pretty well.

When I get the front wheels off I will check for the Nismo springs & shocks and what codes are on those.
