Does any company make any linear springs for the G35 coupe?

 

Hotchkis, but the rear spring rate is softer than stock. Check out the specs at www.hotchkistuning.com

Linear has better performance correct?

Thanks - Joey Avino

 

RS*R's springs are linear I do believe.....

 

Any linear ones for the sedan? Hopefully around 8 kg's (kind of stiff). I would love to put those on

I think that I decided on the RS*R Spring for the 350Z to put on my coupe - the rear are linear, and the front is progressive (even though many have stated they think it is the least progressive a progressive spring can be - only one coil looks progressive) - the .6" drop is alos ideal for what I'm wanting also...

 

I have heard that the stock springs on the coupe are linear. Is this true? If it is I would rather get progressive springs as an aftermarket option.

 

The 350Z, G35 coupe, G35 sedan w/sport and the G35 sedan non/sport all use linear springs as the oem springs. The Coupe and Z use the same oem springs, the shock valving between the two is how they differ, with the Z getting much more aggresive valving.

Progressive springs can be identified by:

1. A specific group of coils visually grouped much closer together. Reason being, when the tigher grouped coils bind, they force a spring rate change where the whole spring get's stiffer. These tightly grouped coils will alway's be found at one end of the spring.

2. A portion of the spring where you can see the coil's constrict or narrow into a smaller diameter. Say the main body of the spring is 5" O.D. and it's 12" tall overall and the top 3" of the spring narrow's it's diameter to be 3" O.D. That narrower portion of the spring will be a softer part of the spring and theirfore progressive.

3. This is rare. A spring that is made in such a way that the size of the wire used to make it, actually changes diameter towards one end. I have heard this type of spring is extreamly difficult to get right and manufacture and I have never seen it actually used.

So, a coil springs stiffness is determined by the number of active coils, the wire diameter used to make it, and the wire diameter of the spring itself.
