Has anybody lowered their car themselves? I would like to lower my car, and I am pretty automobile inclined. I have never messed with a suspension before thhough, and I dont know what it entails. Also, what are your thoughts on using lowering springs? What else will I have to modify if I just get springs?

Thanks.

Andy.

 

Yup. Importriders, Aloha Racing, and I put in our Tein Flex ourselves. It's not bad, just takes patience and some time.

If you get springs you'll need to get a compressor to remove the old ones. Also supposedly you're suppose to replace the strut bolt which holds the spring there (I forgot the exact name of the bolt). This applies for the fronts, the rears you don't need a compressor.

Then after you lower it, you should go check your alignment.

 

Yes I have.

I have created a how to in the G35 section on freshalloy. But for some reason montypics killed the pic files I used for the how to, give me sometime to rebuild those pic files and I'll repost the pics and text here. BTW, I thougt it was really easy to do.

My thought on lowering springs is this. This car come's with a type of coil spring called linear. Yet all the lowering springs I see are progessive. Progressive mean the springs have a softer portion of the whole spring that is designed to lesson the impact of small bumps and impacts. Linear springs have no such soft portion, they give out their full spring rate the moment weight is applied to the suspension. Linear has the advantage of offering better responce and quicker reflexes, something that belongs on a sports oriented car IMO. I would NEVER use progressive springs on a sports car. BTW, all coilovers offered for the Z use linear springs, not progressive.

What else? I'm not a fan on running lowering springs on stock struts, usually the springs are almost always stiffer and you end up being under dampned. Koni sport sturts will be out this fall to take care of my concern on that.

 

Hey Gcoupe 35,
I think that the Nismo S-tune and Tein Flex both use progressive springs. I thought that with progressives, the harder you turn the stiffer it gets? With linear, it's the same stiffness no matter what. Am I correct?

Also, could you explain about struts? How exactly are they different from springs and shocks?

Besides, I hear alot of talk about the Koni's. What's so good about them?

Thanks.
