just put on DMS 50mm on my 34gtr. its really nice coilover and i can go corner much better. my setting is

damp:F and R soft to hard 2 turn repound: haven't touch it yet.

only one thing make me unhappy. it make some noise, when the road is flat, the noise like birdcall (zi zi zi zi) not loud i can't notice it if I open the window or music on. but if the road is not flat. it make some knock, all the noise come from rear (I have cut the rear trim for easy adjust rear suspension).

anyone can give some idea??? is that normal??

Were they installed with new strut tops front AND rear? Skyline DMS 50mm need to be installed with new pillow ball strut tops front and rear, you can't re-use the existing tops at either end.

The chirping noise may be a dry shaft seal, prone to making the sort of noise you describe.

DMS used to supply a circular metal "top hat ring" to weld to the OEM pressed metal top spring seat, and a turned out DMS top spring seat to slip over the top hat ring. That way the OEM top seat / and damper shaft bushes can be reused. Pillow ball tops are not required given the design nature of the suspension.

i only have new strut top on front:( they didn't told me i need rear one:(

thank you for help

so the strut top is not required for DMS 50mm coilover?

i went to Neal lowe today (DMS dealer QLD). they reckon the valve make some chirping noise. actually the front and rear all make chirping noise, i just coundn't hear the front noise during drive. if i press the 4 corner of my car, i can hear the chirping noise on all 4 corner. so I assume its normal. but what the knock come from? :banana:

Pillow ball tops are not required given the design nature of the suspension.

Aftermarket strut tops are required front and rear for the DMS when fitted to the Skyline! We deal with DMS on a regular basis (ourselves and Neil Lowe are the only QLD dealers), and straight from the mouth of the engineer that makes them, they need aftermarket strut tops!

Things must have changed from just a few years ago then, when DMS supplied our ER34 Tarmac struts AND the above hardware to mate up to the OEM pressed metal tops.

The assembly was done locally by the DMS agent with instructions faxed by DMS, and is a good solution that does NOT require new tops.

We still have the struts although they are no longer in the car, unfortunately the instructions were sent on a thermal printout fax so somewhat faded but still clearly indicating they came from DMS.

    • Per Mark Roberts of Sonictune: Mark Robert Author At this time, no. No ETA either 2016-17 models. You will be able to purchase and install a 2018.5+ TCU though   TCU purchasing and pricing info! As we near the release of TCU tuning, I am going to answer some questions I get asked often.   What do I need for TCU tuning? At this time, you will need a 2018.5+ TCU to be able to tune. If you have a 2016-to early 2018, you will need to replace your TCU with the newer version. One good way to know if your TCU is good is if you have auto upshift in manual mode in 1st gear around 6500 rpms. If your manual 1st gear goes to 7k rpm and will hit the rev limiter unless you shift, you have the older TCU.   Why do I need to buy another ecu license/phone flash if I already have it on my ECU tune? The TCU is its own computer module. It is completely separate from the ECU. Because of this, you will be required to purchase a TCU license and, if your tuner has it, the phone flash license required to tune it via phone/bluetooth.   Do I need TCU tuning? TCU tuning is NOT required. However, the faster your setup, the more it will assist in track and dragy time consistency.   If I’m ECU tuned by (tuner A) can I get my TCU tuned by (Tuner ? Yes, since it’s a different module and a completely separate flash, you can have two different tuners. However, it is highly recommend that you have both tuned by the same tuner. For me, my TCU tuning will directly complement my ECU tuning style and features and running my ECU and another TCU or vice versa MIGHT cause some issues. At this time and for the foreseeable future, I will only be tuning my current ECU tuned customers TCUs.     I have a SYVECS AWD controller. Do I still need it? Yes! The AWD controllers main job is to control your AWD system. However, with TCU tuning, you will no longer need the auto-shift function as that will be done through the TCU. The AWD controller will still be very beneficial for racers looking to maximize traction on the launch.     Shift schedule changes: holding gears longer at lower pedal input as well as max shift rpm changes. Please note, the new ECU race rom coming out will address 90% of the shitty drivability issues these cars have through custom maps from myself and Racebox—as well as others I am sure.   Increase shift speeds: as seen in the videos I’ve been posting, the TCU shifts much faster once tuned.   Increased shift pressures: as also seen in the videos, much firmer full throttle shifts.

    • The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week
    • Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.
    • What ECU are you running? This is probably the biggest question. If it's a PowerFC, I'd probably change the ECU and get something newer that will handle the injectors in a nicer way.
