I’m looking to get a new pair of coilovers for my r33 gtst, and I’m not sure what to get. I’m looking for the more budget friendly ones, and mainly for street use, but would be nice if they were able to do some amateur drifting/track aswell. Currently had my eyes on the Blitz ZZR’s, but also the Cusco Street Zero A’s and Tein Flex Z’s. Any recommendations? Maybe anyone got any experience with some of these? 

I’m currently on the Maxspeedingrods coilovers, so I don’t have a lot to compare with. Other than that, the car is properly built. The car is mainly used for fun when I feel like it, and is not my daily.

If there is nothing wrong with your current coilovers, I would not roll the dice on a upgrade to one of the coilovers you've listed above. I strongly expect that you would not be able to tell the difference between the two. 

I'd suggest that you keep saving up the pennies and pick up something from MCA or Shockworks.

Yep, I agree with the above. I was about to suggest BC's as they are absolutely the most tried and true budget option, but you already have....something, so unless that something fails, save up and follow the above advice when the time is right.

After having a look at dyno testing ShockWorks did, going to the Cusco, there would be an epic amounts of difference, especially daily driving a car vs the MaxSpeedingRods coil overs.

From a bunch tested in the below video, ShockWorks found that even a 20 year old Cusco coilover still outperformed all the others tested, and also showed how epically shit the MaxSpeedingRods coil overs are!

This was super interesting! I wish it was a little 'better' a video as I spent a lot of time pausing to compare the dyno graphs with my own printouts which I previously had no reference to...

Happy with my Bilsteins now very much and their handling characteristics which were previously a bit weird to me now make a lot more sense.

Thanks for your opinion on this. I’m just so sceptical to the Maxspeedingrods, and don’t really want them on my car. Was thinking that maybe some quality brand would be an upgrade anyways.

About the Cusco’s from that youtube video, I guess those are some more expensive ones from back in the day. The cheaper ones noe do have twin tube dampers, at least as far as I can read, and I’d like to avoid that. I see that the Blitz ZZR are monotube like the more expensive ones, I was thinking that those might be a great deal, at least from reading the specs. At least compared to the Maxspeedingrods. I do live in Norway, and we have shitty roads here, so I probably don’t want the car to be to stiff.

It's not that it's stiff. If you think about it, the shocks with stiffer dampening will unsuprisingly.. be stiffer.

The issue with the Maxspeedingrods in the video is that they were progressive. So under small bumps they would be VERY compliant, then the bigger the bump is the harder the 'wall' you would hit. The shocksworks and the other digressive brands have different characteristics going by the shape of their shock curve.

ShockWorks actually explain it really really well.

It had f**k all body handling capability.

And they took like 100mm of travel to build up the dampening you need on a fast action.

 

So it means hitting a huge bump in the road like a pot hole, the shock is doing basically until you've already fallen in. So basically, on a big hard bump, it does absolutely f**k all for a few inches, and then slaps you in the back with a sledge hammer.

 

Whereas for good control, and to absorb the bumps rather than being stupidly bumpy / bouncy, you want the really quick acting shocks so that they're able to control the spring immediately.

 

Basically, MaxSpeeding, terrible for track work, and useless on the road, especially if you have lots of bumpy roads!!!

Sorry yeah, by 'VERY COMPLIANT' I could also be referring to 'too compliant'. I wonder if all the springs were similar rates. Surely that'd have something to do with how appropriately damped they truly are.

The dampers with the higher rates would have to be coupled to springs with higher rates. Otherwise you just get massively overdamped suspension, which is no damn good either.

When I was a kid one of my coworkers had a 116 Alfetta GTV. He had Koni Ds in it wound to max. The Konis only adjust rebound. It had standard torsion bars. As he drove it would absorb bumps and get lower and lower and lower until it was essentially as compressed as it could be because the dampers were too much for the poor little bars to push back up against. Was funny as f**k to watch happen - no damn good to drive. I had the same dampers on mine, with stock bars, and only adjusted about 25%. They were great. Would compress and rebound exactly as you'd expect.

I have HSD Dualtechs and would not recommend them. I always planned on replacing them and I've been more so bothered by their excessive stiffness recently. Their time is limited. On another note, I will have a fantastic set of HSD Dualtechs for sale soon 😂

      I'll just leave this quick tip here after reading your joys of getting the car in the air. It should take no more then 10 minutes to get the car safely up on stands.  So for the front, jack on the tow recovery points (marked in red). Put the jack stands under the lower control arm mounting point (marked in yellow). This photo is of a R34 GTR, however the process is the same. For the rear, jack under the diff (marked in red). Put the jack stands under the rear subframe or where the lower control arm mounting point (marked in yellow). Which point you use will depend on your stand, pick a nice stable point.  You've probably already read this but it's worth repeating. When jacking up the car or using stands, stay away from the chassis rails/pinch welds. Even the factory jack point, stay away from that too unless using a factory jack. I used those jack points for years without issue until I turned into an old man and bought a QuickJack lol.

      And this is where the leak is happening: https://www.dropbox.com/scl/fi/7h1vlmg2j5aa7rksvsjc9/IMG_9982.jpeg?rlkey=d3bnpau5f615zmxqmca0llvr7&st=kquvdxvs&dl=0   Apologies but it seems adding an image from a link does not work when the images are in Dropbox.

      Hi all, From the western suburbs here. Just got my 2000 R34 GTT registered today! Got it imported from Japan through a mate who is doing them and managed to find a decent one. This one has only done 110,000 Km and had no body rust etc. so was very happy. I used to own a 25Gt back in 2015 (ate Ramen noodles for years to save up for it), but unfortunately, it got stolen TEN DAYS after I bought it!! Came back from Uni and the car was missing - cops found it in Springvale a month later with a lot of needles  😒 It was too late by then and I had moved on to a different car (300ZX), and after that one got broken into around 2018, I was in a very bad place and decided I would never buy a car again because it was just pointless!!! ~yeah, I have some very bad mojo~ 🥺 But now, with a stable job and a secure garage, I thought I'd get the R34 4D again but not as a daily! I love the R34s but a GTR is still a bit off my pay grade so settled for the GTT instead.    The first step for me is to get this car serviced and have all fluids, belts and spark plugs changed. I might do the brakes at one point too but atm they are fine, the fluids are what I want changed since this car probably sat in a garage for a long time. I'll then get some coilovers since the suspension needs to be changed anyway (the dust cover kit is disintegrating). I'll also upgrade my car alarm to a Viper system and then look at rims and tyres (I'm a sucker for TE37s - might have enough saved in another 3 years for that).   Today: I was planning to do the oil, coolant, air filter and fuel filter change this week. Started on the oil change today and MY GOD what a pain!! I used to think the 300ZX engine bay was cramped - oh I was so wrong! 😂 I've done the usual services on my cars before so it was not like I was going in blind. I looked up all the forum details about what oils to use, what coolant to use, what points to use to jack the car or place stands etc but I did not expect it to be this hard. Long story short - all I managed to do was the oil and filter change. I think I might end up taking it to a mechanic for a coolant change because my SCA stands and trolley jack just can't get far enough underneath to the cross-member and I don't want to be crushed under my favourite car....yet. Side note: In Dandenong, there used to be a shop that lets you hire their hoists - does anyone know if they have those around? I can't seem to find the Dandenong place anymore. I contacted them off FB almost 6 years ago and I'm not in it now. If anyone know of one, that would save me some time going to a mechanic for the basic services. Oil: Dark and gooey but no metal pieces. Oil Filter: Was a b***h to take off but no red flags Air filter: Yucky! Was black (Smells like fuel which makes me think it may have been running rich? - am I way off?)   Concerns: I have but one concern atm and that is that there was a very small amount of oil leaking where the engine and the transmission connect (Automatic). It may be the rear seal? It's not a massive leak and it does not affect the oil pressures or leak oil all along the driveway. It's been falling into the cover this whole time. I've taken the cover off so I can check the garage floor from time to time.  I also have not seen my engine temperature gauge ever sit at cold and slowly move up to the right spot, but that might be because every time I saw the car today, it was running. I'll check that again tomorrow. ATM it just sits right in the middle. I may just be paranoid but I don't want an overheating engine while my gauges say everything is fine. 🙈 Other than that, I'm very happy with the car! Feels like it's about time I went back to spending my weekends driving or cutting my arm on stupid sh*t in the engine bay.   PS: I will post a pic later on because I underestimated soooo badly today and it was dark by the time I finished! PPS: I broke the two damn plastic pins that hold the intake funnel section to the front bar. This is the piece made to bring cold air to the airbox. The connection to the airbox is fone, but the two clips just broke off! Should I be worried? Anyone else done that?
