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?

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

Anyway, picture attached :P

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

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 :P

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 :P

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

im seriously hating your car more and more bis-e-bee :D

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.

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.

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.

      Wife wanted basket things in the wardrobe in our temporary house. Thought about ripping our the wardrobe and fitting the entire IKEA set, but it's a temporary house and we want to move in a few years. So IKEA advertises this as a 50cm unit, however the actually basket and rails measure 46cm wide. Only issue was depth, IKEA stuff is quite deep, where as the builder special junk is super shallow at less than 40cm. Send it, chopped the rails, then offset the mounting holes, job done, happy wife, less shit scattered all over the bedroom. Did the same to the other side too. Also drove the Skyline shit box today, dropped off oil at Supercheap Auto. I didn't realise they only now take max 2x bottles per visit. I visited 2x Supercheap Autos.

      I've seen similar actually in my situation. You never know what tables are attempted to be used when the car thinks it's -99C or +200C. The fail state is not usually that extreme but you know what I mean - it was in my case though! This is where being able to read all the sensors is useful cause you see this stuff really quickly.

      The above is very important. However as long as you keep timing relatively low, it's plausible to make your own knock ears and plausible to learn to tune with a modern ECU that can do wideband O2 correction like a boost controller. I mean if you only have one viable road to even drive the car on, learning to tinker to this level may be worth doing given you can't do much else with the car...?

      I find the fact that the rear plate has to be bent inwards at the rear not so bad: but the front is just awful: It's like come on. (these are my very old, now retired/turned in plates) TBH it is a lot of money to fix a minor issue, the fact I said "I'll never really spend the money on doing this" is why people ended up buying them as a gift for a 'car guy' who can be hard to shop for.. for car guy things.

      I just bent the ends of my premo plates. It even went through Regency like that after the engine conversion and the inspector (a great bloke!) just squinted his eyes and said "I didn't see that". Plates, and how they look, are just something that have zero importance to me.
