Arizona Z Car Coilovers

[600Z]

Hi Guys,

Well the time has come that one of my shocks has bleed its oil out into the strut tube, no wonder it was starting to handle a bit funny  

Arizona Z Car use to use HSD shocks with their coil overs and I'm wondering if anyone might know what model/part number they are through HSD. HSD have changed there housings now to a larger size by the looks of it which doesn't help.

Otherwise, does anyone know what other shocks might use 50x2mm housing to save me from having to cut the welded tubes off.

 

Cheers,

Justin

Give MCA a call it’s quite probable they will be able to either re build what you have or supply you with replacements.

Hi Jeff,

Thanks, I have sent them an email with pictures etc to see if they are able to help me. If possible although not the cheapest option but it would be nice to run a set of there's for sure, nice gear. I use to deal with them a little bit back in the early 90's (showing my age now lol) when i was building a 2.1L with a rare 219 cylinder head and they have always been great.

Do you know if Murray is still alive? I had a set of webers that Iain Stewart (his co driver) did a lot of work on to get them to run better but then changed to 48mm dellortos which were sooo much better. Hopefully they will be able to come up with something though i might have to cut the welded tube i have on off and start again.

His 1200 coupe was a weapon, a friend of mine at the time ended up with his cylinder head and 55mm webers from that on his 1600 drag car and i still have one of their ported heads from back then collecting dust lol.

I don’t know Murray well. I have chatted to him a few times at rally’s over the years. Last I spoke to him was at an APRC round in QLD when he came past our service park to see Phil from PCD Engineering and had dinner with us. 
I am running a set of Reds on my Z and are very happy with them. 
I hope he is still kicking as he is not much older than me 🙂. 
His 1200 was a rocket, as were a few other cars during the Group G days. Like rotary powered 1600s.

I don't know Murray apart from saying hello back then as i was dealing with a guy called Dave who has a dark green 1600.

With the Reds you have what spring rate do you have? and me being in Tassie the roads are not the best at all, sometimes i feel like i should wear a kidney belt lol. 

My zed that have the coil overs is the orange one with the 6.0L in it but from what i remember there isn't too much difference in weights so I'd be thinking I would get away with the same or similar spring rate.

Oh and Murray Coote Automotive don't do any that will fit into my welded on tubes so i would have to cut them off and start again, which may not be a bad option.

Bugger. 

From memory (Not as good as it once was) the rear springs are 5kg (280 lbs) and the front are 6kg (335 lbs). The spring rates are as per MCA. It is quite stiff and you feel the bumps but man it’s fun and corners on rails. I run the adjustable one click from full soft.

Thanks for that, talking about memory i had my strut out just the other day and you think I can remember what springs are in the front of mine 😆 bit it's sounding like yours are firmer. I know I have to preloaded my quite a bit to get the ride height in the middle of the shocks travel.

One click from the softest you don't have them bottoming out?

 

Justin

[CBR Jeff]

Haha

No they don’t bottom out. The soft setting is for road driving around town. Faster speeds on rougher roads would call for a harder/slower setting. The sag is about 30% +/- front and rear. I don’t run any preload at full droop to speak off just enough to secure the spring.

I'll have to check my spring rate tomorrow but if i didn't preload them I wouldn't have any travel up left or very little I think. Just enough preload to hold the spring sounds good.
