Over the course of the last few months, my coilovers had gotten pretty noisy over small bumps. Once at speed (hgihway speeds) they were silent, but over small ruts, there was a sharp clunk that I could not eliminate.

After doing some research, I decided to order the Cusco std mounts for these coilovers. I have the Zero2 coils, but had purchased them with the pillowball mounts. These new mounts use a rubber inner cushing with a metal sleeve (where the threaded up portion of the damper fits through).

Install was relatively easy - we had to take each front strut out and swap upper mounts. The nuts on each side were very stubborn, but we eventually got them off. On one of the nuts, the nyloc portion hadstarted to sheer off onto the threads, so we decided to retap the threaded upper portion on both coilovers for good measure. The new mounts include the dust boots and new nuts and washers for all around, so we were good to go. We also had to redo the rideheight up front, since there is around a 2 inch difference in the heights of the mounts between pillowballs and the non pillow versions. Usually, pillow mounts are taller than rubber ones, but these were the opposite. On the Zero2 rideheight adjustment can be done via the whole lower mounting bracket or via the spring perch. Since this was a pretty major rideheight change (around 2 inches), we did the adjustment via the lower mounting bracket. All in all the fronts took around an hour and half to do.

They have now been in the car for a week, and I gotta say I am LOVING them. For anyone considering these coilovers, they are fantastic, though the non pillowball is probably the way to go simply for the noise that can be produced down the road. Cusco sells the coilovers with and without pillowballs and the non pillow version, and the non version is a bit cheaper as well! Granted our NY roads stink and I drive quite a bit in NYC, etc, sot he car can get a workout sometimes. I am sure this contributed to the noises eventually rearing their ugly head.

The great thing on the Z is performance wise, I really cannot see what is lost, since camber changes are not done at the mount. Only thing I could see is the steering response being slightly quicker with the pillowballs, though I have yet to notice a difference.

Now and has a even over large ruts, these are totally silent - not a squeak, or clunk to be heard.

so its basically pillowball upper mount with rubber cushing?
were you using stock rubber mount ?

 

Glad your happy with the change.

The guys in Japan warned me the pillow-upper mounts were nosiey and I hate noises like that, so I got the std mounts.

Adam, Can you get replacement bump stops for the Zero-2s?

 

Yes I am sure we can get them - I'll check into it today

 

Thanks alot.

 

any chance these would fit the JIC coilovers? I would love to put an end to the noise.

 

No they are only for the Cusco's

 

Hey Adam, Any luck?
