Re: Aftermarket springs vs stock shocks. READ BEFORE POSTING

I don't want to lower the sled but I'd like some better springs and dampeners.
Who's making something like that? I'm mostly familiar with Penske when it comes to suspension...
Harsh ride? My other car is a Cooper S and I'm a long-distance motorcyclist; I put Traxxion Dynamics suspension mods on the bike.

Safety Fast,
Bill

A nice tidbit extracted about of the original post can also be attributed to what I believe others refer to as "Eibounce" (bouncy ride on Eibach springs...or other aftermarket lowering springs for that matter) where the car has a bouncy ride due to performance lowering springs being paired with stock/oem shocks and struts.

...this design damping ratio is a consideration when springs and shocks are picked for your Mazda3 at the factory. When a stiffer spring is installed. The original damping ratio is lowered. This means the system is under-damped compare to the original set up and the system will take more cycles before coming to rest whenever an external force is applied to it. This means all things equal, the shocks will see a corresponding higher number of cycles in a given fixed time period. However, all things are rarely equal in real life applications. Consider this, while the under-damped system is going thru its extra cycles, but before completing them, another external force is applied to it and this new force is completely out of sync of the vibration. It will actually stop (or cancel out part of) the vibration that is yet to be completed.


I think the moral of the story here is to have "properly matched" springs and struts/dampers so they won't be operating at different "cycles" in response to forces exerted upon them. OEM struts may be fine with aftermarket springs for durability-sake for most people, but they may not be ideally matched, rate-wise...imo.

so in response to this. which is exactly what i have sort of been looking for in regards to an answer..... i have some other opnions as to why mailed to me by a friend of mine.

the advantages to coilovers are that you can run much higher spring rates because the shocks/struts that come with it are valved stiff enough. you also get adjustable height. most coilovers also offer stiffer springs than you can find when just buying springs.

for example for the miata i'm running a 394 lb/in front spring and a 330 lb/in rear spring. the highest rate springs that fit the stock shocks are 318/233.

the next problem with running stock shocks is when you lower the car, you lose suspension travel. basically your drop is eating into your suspension travel. also depending on how high you go onthe spring rates it may not be able to handle it. basically you'll get a crashy/jarring ride and less traction on the track.

coilovers fix this, they have shorter than stock shock/strut bodies. so you maintain all your suspension travel while dropping the car. and design their valving to match their spring rates.

you can get just springs and run your stock shocks/struts, if you dont increase the spring rate too high over the stock spring rate and are conservative on the drop you'll be fine. since you are upgrading the suspension based on track performance, i would save up for a set of coilovers. skip the springs unless you can find some that have a high enough spring rate, but then there's the problem of finding a shock/strut that is valved firm enough for those rates.



my question here is... basically if you dont have a high enough spring for your stock shocks - you will actually get a bouncier ride due to the shock already being compressed and having little to rebound upon?

so. its almost worse to ride tuner springs depending on the stiffness of the original shocks?

texas, as far as im concerned, is definitley NOT for lovers....

According to Cobb, a fairly respected name in this business, the factory springs are overmatched by the factory dampers. Their replacement springs are 15% stiffer front and 25% stiffer rear if I remember correctly, and their testing indicates that the factory dampers are a good match for these. In fact, for purchasers of their suspension kits, they recommend keeping the factory struts.

Perhaps the gene pool could use a little chlorine.
