Just thought I'd share with you guys... I guess I should be saving for some coilovers....maybe my next big mod.

 

hmm not something im gonna do...just b/c i know i'm prob. gonna sell the G or upgrade it in like another year or 2....just my .02!!

 

I slept with purias wheels. they are fantastic.

 

so many suspension threads rehashing hearsay such as "I heard such and such is bad" or "on my civic, i did such and such" - check out these good resources:

^^ good stuff vic!!

 

I have an idea of how linear vs progressive works but please correct me.

Eibach designs and manufactures both linear and progressive springs and progressive spring systems. Progressive systems use two or more linear springs of different spring rates called main and tender springs. The tender springs have a lower spring rate than the main spring and are made from a special wire with a trapezoidal cross section. After winding, the coils of the tender springs can collapse flat against each other providing a stable platform for the main spring to bear against.

Off-road racing vehicles use this type of suspension for soft spring rates rising to higher rates as suspension travel increases. Race cars with aerodynamic downforce can utilize the main spring to support the car at speed and the tender spring in slow corners. Formula Ford suspension tuners install small tender springs in the rear suspension to prevent lifting the inside rear tire in slow corners.

I read this but cant quite make sense of exacty how it works.

 

My layman's understanding is that progressive springs are more comfortable because the lower spring rate portion compresses over minor bumps, etc., whereas the higher spring rate portion absorbs major bumps. Linear springs are arguable better from a performance perspective, because they are more predictable at turn-in, as you don't have to wait for the car to "set" through the lower spring rate portion. Just my two cents.

 

you should go shocks or a coil over set just in case. My friend with a 03 350z went with eibach springs. It was fine at first, but after about 5 months, his car was bouncing all over the place. His stock shocks/struts gave out, and he ended up going with a coil over system.

 

I didn't read any of the threads posted, but not sure understand why people sweat coilovers? would a shock/spring combo not be as good for much less? I get the feeling most coilovers are super stiff, such as the tein basic. I doubt most people lowers and raise their car that often (if ever), unless they have an allignment check machine in their garage. Just not sure I understand the hype. To me, the d-spec, 350z h-tech seem like a killer combo. Am I missing something?

i think that the tein coil over system with edfc is awesome, but it costs too much for me. I'm happy with my tokico's and htechs.
