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).

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.

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:

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.

      Yeah, it's getting like that, my daughter is coming over on Thursday to help me remove the bonnet so I can install the Carbuilders underbonnet stuff,  I might get her to give me a hand and remove the hardtop, maybe, because on really hot days the detachable hardtop helps the aircon keep the interior cool, the heat just punches straight through to rag top I also don't have enough hair for the "wind in the hair" experience, so there is that....LOL

      Jacks that fit under GTR lips that can reach the subframe?

      On BMWs what I do because I'm more confident that I can't instantly crush the pinch welds and do thousands of USD in chassis damage is use a set of rubber jacking pads designed to protect the chassis/plastic adapter and raise a corner of the car, place the aforementioned 2x12 inch wooden planks under a tire, drop the car, then this normally gives me enough clearance to get to the front central jack point. If you don't need it to be a ramp it only needs to be 1-1.5 feet long. On my R33 I do not trust the pinch welds to tolerate any of this so I drive up on the ramps. Before then when I had to get a new floor jack that no longer cleared the front lip I removed it to get enough clearance to put the jack under it. Once you're on the ramps once you simply never let the car down to the ground. It lives on the ramps or on jack stands.

      Nah. You need 2x taps for anything that you cannot pass the tap all the way through. And even then, there's a point in response to the above which I will come back to. The 2x taps are 1x tapered for starting, and 1x plug tap for working to the bottom of blind holes. That block's port is effectively a blind hole from the perspective of the tap. The tapered tap/tapered thread response. You don't ever leave a female hole tapered. They are supposed to be parallel, hence the wide section of a tapered tap being parallel, the existince of plug taps, etc. The male is tapered so that it will eventually get too fat for the female thread, and yes, there is some risk if the tapped length of the female hole doesn't offer enough threads, that it will not lock up very nicely. But you can always buzz off the extra length on the male thread, and the tape is very good at adding bulk to the joint.
