I would like to see are there stiffer than stock springs that don't lower the car?

Everything I see advertises that they lower the car. I don't want the car lowered.

 

Call concept Z, there are a few that only lower a few mm, don't remember what the spring rates were on them. Most of the springs on their site do list spring rates but they might be able to help you quicker

 

tein s-tech are a very minimal drop .. but i felt they were soft

i had the eibach pro-kit, i felt they were perfect but its about an inch lower

 

just chatted with a rep for concept z. No joy. All their springs lower the car.

 

.3" drop
check these, very minimal drop, seems like there was another set that was close to it,

 

The OEM Nismo springs on the 07-08, NOT the S-tune nismo, are significantly stiffer and won't lower the car but are also probably your most expensive option. They need to be paired with shocks that can handle a stiffer spring like the OEM nismo shocks, Koni yellow, or maybe bilstein. Any stiffer spring should also be paired with upgraded shocks.

Nissan lists them as not made any more so might be hard to find or you will need to look used.
Front spring - E4010-1A33B
Rear spring - E5020-1A33B

A link to one of mic's old sale posts with pictures and a link to his review of the suspension, also in the FS post. Notice the OEM nismo front springs are linear. The S-tune front springs are progressive and the s-tune suspension will drop the car.

Rancor,

Read both threads. LOTS of great info.

I have a bid on some OEM Nismo springs, let's see if they accept my counter offer. Since I haven't received the B6 Bilsteins yet, I can install them after I get the springs. Maybe, hopefully.

 

2008 OEM Nismo Springs, got them used for $155 delivered.

Good deal?

I ran the VIN on the decoder - comes back as a 2008 NISMO 350Z - so the springs should be here this weekend, if the cows come home and the creeks don't rise.

 

springs and shocks assembled!

Bought this set years ago from Sears. They've been a Godsend!


Gotta love electric impact guns!

 

Rear springs swapped out. From wheels up to wheels down was an hour. Really happy with the results.

 

Like a Boss, great choices. You'll be very happy w the Bilsteins.

 

I got to drive Stitch a bit before my deployment. Much better handling between the shocks and the springs.

Hopefully, once I get home and everything returns to some semblance of normalcy, I will get to autocross and see how much better the changes affect the handling.
