Anyway, I’ve just spent an hour or so Googling for a definitive answer with regards to oiling or greasing the threads on adjustable coil-overs.
I haven’t fitted mine yet but all the sites I’ve seen seem to contradict each other. Some say they need oiling to keep the threads from going rusty, Some say no oil because that makes road grime stick to them and then it gets caught in the threads, Another said use grease or you won’t be able to adjust the spring platforms when theres any load on them, And one says no to oil as the locking rings need friction to stay tight… ???
I just put a thin mear of copper grease on the threads of my aluminium Protec (P-5 Puredrive) shocks. Haven’t though noticed any corrossion on any parts of the shocks after 7 months now.
I’m wondering if copperslip would efect the friction needed to “Lock” the seats in place. Have you moved the spring seats in those 7 months and did they still feel tight?
I had a set of Cusco shocks when I first bought my Roadster back in 2000, and I must say that they were the best performing shocks of all the types I’v had since, however they started to leak and they cannot be repaired. Back on topic I used to put a thin layer of marine waterproof grease on the threads. If you need to adjust them, you have to meticulously clean the threads otherwise the collars won’t move. I used diesel to remove the grease. I did toy with making some boots out of soft rubber and a couple of Jubilee clips, but that never got off the ground
I have Cusco coil-overs on the front of mine (don’t ask about what’s going on at the back end). The threads are dry and have been since I got the car three years ago. No problems with corrosion and they brush clean with a few minutes effort. My car is used all year including on salted roads
However, this may not apply to your coil-overs as even a slightly different surface treatment could mean an entirely different reaction to salt and water and only the manufacturers will know what works best (unless they don’t do any testing in which case they are even more hugely unprofesisonal than not replying to your enquirey would suggest).
I sent an email when I received the coil-overs praising the speed of delivery, The quality of the machining/finish of the items and stating that if this is the usual level of service they offer I’d not question buying from them again.
I got a reply asking what else I’m looking for.
Now, It was late and I didn’t really put that much thought into my reply… I think I might have said something along the lines of “All the rest of your stuff is OTT for what I’m after, I want some 2 or 4 pot callipers and a sensible fast road clutch (Ie, Not one of the 3 puck ceramic “on or off” types)…”
I didn’t get a reply to this.
After a little googling I realised where I’d seen the name and logo “Apex performance” before… It was down the side of the s13’s and the yank V8 powered Skyline they built and use for drifting competitions…! It also dawned on me that there cars and company have been featured in all the jap car mags over the years.
I think I may have inadvertently said the equivalent of “I want a cheap family runabout” to Maserati !
As I said, I feel a bit of a pillock.
I’m sure if I emailed them with the coil-over care question I’d get an answer (They strike me as a very professional company, And as I said, The coil-overs are stunningly well made), But the embarrassment over my last message to them means that I don’t necessarily WANT to ask them.
