Noisy Coil-overs

[Flyboy]

Are COil-Overs usually very noisy in operation?

[dotdog]

I had Tein Coilovers in my old GTiR and they were quite as, no noie what so ever

[Flyboy]

ive got Teins in the Trueno.... Theres lots of rattling and squeeking... the backs hiss when they go over bigish bunps...

[dotdog]

The teins rattled my pulsar to bits, but the shocks never made any sound

[Dr-X]

My mate has teins in his S14, fairly noisey over bumps and stuff, slight hissing, odd creak, etc.

[Flyboy]

Is it bad if theyre excessivailly noisy? I cant tell whether the teins are noisy or the rest of the suspension...

[Flyboy]

Found the problem..... Not the suspension at all... The engine mounts instead!!!

most coilovers are always going to be noisier than factory set-ups due to the simple fact that spring rates are usually a lot firmer and linear rate whereas factory springs usually have some form of progressive rate, also a serious coilover usually has little in the way of rubber isolation in it so you have a much higher level of NVH transmission through shock and spring and then through into car body. In a standard setup most top plates have a high portion of rubber in them likewise the spring sits in a rubber isolater top and bottom all of which is usually redundant in a set of coilovers
