Attn CRZ owners with Ksport Coilovers

[Ksport]

Hey guys I just wanted to bring a situation that was bought to my attention by a forum member here on his coilovers.

First, customer emailed me with pictures the top exposed part of his strut was starting to get some surface rust. This was odd because we had never seen this issue before. We dug a little deeper and found out on the CRZ the drainage for the water off the windshield put the water right at the top of the strut mounting point (odd to say the least) so this is where the rust would have come from. Then we also looked back to see why Honda did to eliminate this issue. We realized Honda's portion of the strut that is exposed was a little shorter and they also put a small rubber cap over top to help with the moisture exposure. I bought this up to my friend that works at Honda and he mentioned the rubber cap will help in the short run but over a longer period of time the OEM strut that is exposed will begin to get some surface rust on it also.

Solution we came up with would be to add a silicone cap the exposed strut area to limit the amount of exposure it has to moisture and that will eliminate surface rust build up.

** I am not sure if this is also an issue with other manufactures struts being too long for the OEM rubber cap.
** keep in mind this is ONLY on the front since

Here is what OEM looks like (notice rubber cap)


Here is what Ksport looks like


This is the rubber cap I recommend purchasing
Stockcap Rubber Caps and Rubber Plugs | Rubber End Caps
** You want to get the EPDM caps for this application**

This may be an isolated case, I talked to another member here over the phone who has the same Ksport coilover kit, had his for a year now, and he has no rust issues.

Well the problem only persists where your in a heavy moisture environment ie rain sprinklers it seems. So depends if that member sees less moisture than you.

True, but I'm in Nashville average rain fall here. I wash the car every other weekend.

put a little bit of lithium grease on it to prevent it from rusting

UPDATE.

Ok after doing some research and trying to get Ksport to see if we can get my warranty to cover this (since the rust made it's way down inside the hole where the key goes), I talked to TEIN on the phone and they use zinc in the thread to keep this very thing from happening, because of where the strut tower is located where water will hit it they pre thought this problem, actually they do it to all their kits to keep rust away. Letting you guys know. TEIN is also concern that the seal will get damaged on the piston rod and cause leakage.

Here's Ksport response:

Ok we don't care about what other manufactures say about their products. They do not make our coilovers. What they make is always different. All our shocks are covered in anti rust paint and everything so it doesn't rust. Most the time people leave their adjustment knobs in the coilover at times.

Designer –

I apologise if the response from our service department sounded strange, but I will clarify. This design of the exposed stud on the upper mount is the same design we and nearly every other manufacturer use on nearly every single application we make. We have never had one incident of rust on any of these as every single one is electroplated to prevent rust. But on this application where you must remove the top nut and reinstall on the crz the coating can become worn, and the steel can be exposed, which may lead to eventual surface rust. As for tein using zinc to prevent this issue as you said they have thought ahead, doesn’t pertain to the hole that will be exposed if you remove the dampening knob, as theirs are not removable. But any rust should be able to be removed with a wire brush, we have never in 9 years of production seen one case of rust that was not cosmetic and only surface rust. As for tein saying our seal will get damaged, I really don’t know what that is all about, it makes no sense at all honestly and has nothing to do with the area in question as the shaft is not the relevant part, and wil not rust due to material and constant lubrication from the shock action. If you have any other questions or concerns feel free to contact me.
