View Full Version : coilover settings


08-21-2005, 10:45 PM
i just installed my megan track series coilovers. i took them for a ride and it was really bouncy. im new to coilovers, so its the stiffer it is the less u bounce right? or if its too stiff it bounces more? not sure... but i was just wondering if u guys can tell me what dapening settings u guys use and how it is. and ideas for a smooth ride, but at the same time pretty stiff so i dont get too much roll... thanks

this is kinda off topic but i also had lotsa noise coming from my exhaust, kinda like it bouncing off the bottom of my car i think. i just had sr20 installed. is it cuz its straightpiped and like nothing holding anything back to keep it steady? does what i make sense? anyways if u got any ideas please tell me... thanks

um, its really bouncy because your using 12/10 spring rates on the street. lol.

so how do i make it less bouncy? stiffer or softer?

Softer. If you do it softer, it will take longer to bounce up. If you put it stiffer, the shock will bounce up faster.

you sell them and get some coilovers with more logical springrates ;)

I think what everyone is saying is that you have race coilovers that you are using on the street... the spring rates are too high to use on the street.

you'll feel like you're in a shaker. You'll get sick, and puke. Everyone agrees, 12/10 is too harsh on the streets. Get their 8/6 coilovers. Gimme the 12/10s!

High spring rates compress less, and expand much faster than lower rates. Because they compress and expand this way, this higher 'frequency' can feel more uncomfortable to the driver. You have to make sure that the car isn't continuing to bounce after the initial loading and unloading of energy of the spring (it would signify that the shocks are not properly limiting, or dampening, the spring from expanding and contracting too much)

12/10 is extremely high for the street, for a car under 3000 lbs. You might have much less traction over bumps because less energy is stored in the spring and is being transferred to the wheels + chassis, causing the car to 'jump' over bumps and the tires have less contact with the road.

8/6 is probably the best compromise for street traction + performance, and is what we offer on most of our Tanabe Sustec Pro systems, and 10/8 (DDs) has been very reasonable to maintain some traction over bumps and other road irregularities.

^^^ I would def. listen to them as far as tech specs and advice on coil-overs. You should have bought the reg. MR setup.

It also depends on exactly what kind of 'bounciness' you are experiencing. If you hit a bump, and the car continues to oscillate for a couple of cycles after the bump, then your damping is set too low. On the other hand, if by 'bouncy', you mean that the ride is too harsh and you are losing all of your fillings, then you can try to lower the damping setting to soften your suspension somewhat. However, the difference you will be able to achieve is limited since your springs are so stiff.

ps. The proper term is 'damping', not 'dampening'. Dampening relates to making something wet, or soundproofing. Damping is the reduction of the amplitude of an oscillation.

Dampening also means to restrain (the dampeners restrain the spring from continuing to oscillate), but it is true damping is the correct technical and physics related word. Both words are still useable... 'Dampening' although technically not as accurate as damping, is commonly used, since it is easier layman's term to quickly associate to dampeners aka shocks or struts. :D

We can't recommend using another manufacturer's products for obvious reasons, but definitely 12/10 should be reserved for nicely paved tarmac only. We do have custom springs rates, lengths and diameters, but we can't guarantee the quality of that suspensions valving, whether they are using the same dampeners for their 8/6 and 12/10 setups. I would imagine it is the same dampeners on both setups.

Track are for track, really bumpy on street. SHould have bought the other MR CO.

i use pro dd coils on the street and track and i am very impressed with the streetability of the 10/8kg setup, the valving on the shocks works very well with the springs when the shocks are set on soft it is very good for the street now on hard setting the car feels incredibly solid.

dds rule
have them on the s14
amazing coilovers.
very very streetable
run the softest front and 2 rear for street and track.
dont need anything higher, feels great

i'll be able to comment on that soon =P
