What type of oil in dampers?

[H8NSKPAUL]

Hi guys,

As some of you know I am in the process of converting a standard set of suspension legs into coilovers. I have got stuck & need help with identitying the type of oil that I need to put in the leg? what viscosity to use? I am sure this is crucial to the performance of the damper.

Any help is greatly apreciated.

Many thanks,
Hans.

yeah transmision fluid is good, thicker the oil the harder the damper will be

How hard do you want it, I did the last silvia with gearbox oil and it was hard.
You can also overfill slightly to get them harder still.
Off the top of my head I think it's 280ml of fluid you need to put in.
