These two items might be discussed before, but I am only be able to find the spec. on both......Anyways, anyone know what's the stiffness difference btw the Tein Basic and the 350Z H-Tech??

I know the H-Tech is a lot cheaper than Tein Basic, and still there are many ppl who appreciate the Z H-Tech very much!! So just wondering:

1) Will there be anything bad to the car, if I using the H-Tech for Z on my G coupe??

2) Compare to Tein Basic, how's their stiffness differences? Just a bit?

3) Is the S-tech for G, lower than /or stiffness than, the H-tech for Z?

Thx for all advices!

 

Anyone??

 

Here's a breakdown:

H-Tech springs
Infiniti G35C spring rate (lbs/inch): 325 F / 263 R
drop (inches): 0.6 F / 0.3 R

350Z spring rate (lbs/inch): 358 F / 375 R
drop (inches): 0.3 F / 0.2 R

S-Tech springs
Infiniti G35C spring rate (lbs/inch): 358 F / 274 R
drop (inches): 1.2 F / 0.9 R

350Z spring rate (lbs/inch): 386 F / 402 R
drop (inches): 0.7 F / 0.6 R

Tein Basic
Infiniti G35C spring rate (lbs/inch): 503 F / 503 R
adjustable drop (inches): 1.5 F / 0.9 R - suggested

350Z spring rate (lbs/inch): 503 F / 503 R
adjustable drop (inches): 1.0 F / 0.8 R - suggested

If you plan on getting the Tein springs, I would suggest going with an adjustable (damping) aftermarket shock. If you used the stock shocks, who knows when they'll end up going because of the higher spring rates. The drawback with going with the springs is that you won't be able to adjust the height of the drop.

I think I'll go with shocks, rather than just springs because this may cost me cheaper in long-term.

A frd of mine just told me that his stock shocks was end up after lowering w/ spring in a year and three months!

 

More info to my previous post:

Tein CS - MSRP $1760
Infiniti G35C spring rate (lbs/inch): 391 F / 391 R
adjustable drop (inches): 1.0 F / 0.7 R - suggested

350Z spring rate (lbs/inch): 391 F / 391 R
adjustable drop (inches): 0.4 F / 0.8 R - suggested

Tein Flex - MSRP: $1860
Infiniti G35C spring rate (lbs/inch): 671 F / 671 R
adjustable drop (inches): 1.5 F / 1.0 R - suggested

350Z spring rate (lbs/inch): 671 F / 671 R
adjustable drop (inches): 0.9 F / 0.8 R - suggested

If you plan on getting the Tein springs, I would suggest going with an adjustable (damping) aftermarket shock. If you used the stock shocks, who knows when they'll end up going because of the higher spring rates. The drawback with going with the springs is that you won't be able to adjust the height of the drop - some shocks may have some height adjustment with the lower spring perch; not all shocks have these, at least for the fronts on the G. With the full coilover setup, height can be adjusted. Tein Basics & CS only adjust for ride height whereas Flex can adjust for spring pre-load, ride height, and damping. For ride comfort, the CS would be suggested. If you're a performance oriented driver, then I would go with the Flex (if you can afford) or the Basics.

Also, if you wish to drop your car more than ~0.7 inches, I would suggest getting a camber kit. There are a couple of places that manufacture camber kits: 350evo, Performance Nissan, and Kinetix. Keeping the stock rims is no problem when lowering your car.

For me, I'm planning on going with the Tein Flex w/ EDFC & 350evo camber kits once I finally decide what rims to get. Install should be easy for full coilover & camber kits with the only thing I'd have to pay for would be the alignment.

Keep in mind, I only focused on Teins but there are so many full coilover setups out there: HKS, JIC, Zeal, Ohlins (expensive!), etc. Bang for the buck, you can't go wrong with Teins. Good luck with whatever set up you get!
