king springs yay or nay

[theremm]

Any reviews particularly for 240z? Considering the 30mm low, just looking for a slight drop and street use, better wheel fitment etc.. Not interested in coilovers as don't want too stiff..

 

Have (new) KYB Excel G's in front and rear. Stock wheels at the moment although have 14x7.0 -3 watanabes which i am planning to run with 205/60 (or 55?)/14 tyres..

yay and locally made too!

I have then and I am very Happy with them

I got the lows but it hasn't dropped it any more than standard.

They are OK, I cut 1 full coil off the front ones because I wasn't happy with the ride height (it looked like a hummer) the spring rate seems pretty good for a street cruiser but prob not quite stiff enough if you were going to do alot of track work.

I had my front springs tested, they were about 185lbs/inch when measured at ride height (progressive)

As others have mentioned in another thread, you don't have much shock travel but I haven't heard my shocks (Tokico Illuminas) bottom out yet, I run the progressive bump stops from SWM which may make a difference, don't know

 

Also, the springs even at original length are not quite captive in the standard struts. I have put hose clamps round top and bottom to prevent them popping out. (Not very likely but I'm just a belts and braces kind of guy)

Cheers

+1 for the King lows.

Reason why the new ones fitted were about same height as old original stock springs was,,,,,

The old ones had, after 30+ years,,, sagged a bit!

 

Bit fancy using hose clamps to retain,,,,,

I ise two bits of fencing wire, at each of tops and bottoms,,,,

Well I'm not impressed.

I assumed their 'standard' springs would pretty much match the original factory spec springs (rate & length) so as to restore OEM standard ride height. And that the 30mm lower option would just be a little stiffer & set a car's ride height about that much lower, as a 'performance' spring. But no - BOTH versions are the same spring rate.!?!

I bought a front & rear set for my early-74 260 2-seat, opting for the 30mm lower. The rears are barely captured by the retainers, & so stiff that the ride height ends up slightly higher than the tired originals; just as well I didn't opt for the 'standard' ones!

Worse, the fronts are not captured at all, missing by about 10mm on full droop, & I'm already running the later shorter 260 front struts. I shouldn't have to wire them in place, that doesn't seem a safe fitment, wouldn't expect that to pass an inspection. They're quite a bit too short, as verified by my factory 260 manual - which gives a range of factory spec springs used for different markets, 2-seat, 2+2, standard or performance etc.

Springs are a function of length, wire diameter, coil diameter etc. IMO the ones I purchased for my 260 are too stiff & - on front - way too short to fit correctly, AFAIAC the specs are quite wrong. Their tech dept advice was that they measured off an actual car (goodness knows what); but why not just use OEM specs as a starting point? So I'm not at all happy.

Hi,

 

Have you stuck with them or gone with another make ?

 

Cheers

Perhaps someone else can confirm, but are early 260z suspension same as 240z? Reason I'm asking is that if you put late 260z low springs in a 240z you will get standard height-it will not be lower, and if you put 240z springs in a late 260z, they will be extra low-about 60mm.

 

I was wondering why my late 260z was so low compared to others with supposedly the same springs so I checked the part numbers-the previous owner had installed 240z low king springs so it's too low and blown the shocks as well. Not sure if he did this unknowingly or just wanted to be extra "hectic".

Hi PB260Z - they're installed, several months ago, but my car (which I've now owned 30 yrs!) has long been off the road in storage, gradually I find time to fiddle with it but other things like kids, house reno, & a Mustang, take precedence. One day...

I digress. Those springs will be coming off again as they don't suit & I'll get the original springs re-tempered but re-set a little shorter than stock, maybe 25mm or so.

 

Sydney mike - my car is an early '74 2-seat, has same suspension as the late 240, a bit taller than the late-'74-on 260s. I don't know if there were just 2, or more, 260-type struts. My Nissan 260 factory manual lists a whole range of different springs - lengths & rates - depending on whether 2-seat or 2+2, which market car sold in, A/C or not, & whether standard or 'performance'.

I bought my car in '84 & a little later discovered that one front stub axle was damaged. I went to a Z parts guy & he didn't have a matching strut but did have a pair of later 260 ones, which are shorter & fatter, so I trial fitted those (complete with springs) & they dropped the front down nicely, which looked & felt better. So purchased them, a quick fix for my only car at the time rather than chase around to find someone with the right gear to repair the damaged one.

 

My mistake was not doing my homework first on what I was getting, as soon as I got them out of the box I thought they looked a bit on the short side.
