Hey,

I'm looking for some Springs for my 2008 Touring.

I saw over at mynismo.com
NISSAN MOTORSPORTS Race Spring Kit

$420 for set.
Here is what is listed.


NISSAN MOTORSPORTS race spring kit for the 350Z/G35. Could be used with OEM dampers. Spring rates are 690lb/in each. Please allow 30 days for delivery after purchase as these parts are special order only and not in stock


99996-65Z30US NISSAN 350Z 2003-2006

T2 Nissan Motorsports springs are used by all the SCCA T2 350Z racers. I believe some are actually running them on their street cars here as well.

I was like they look like race springs.

690lbs that would be very stiff riding.

I have them on mine, but not with OEM struts. I have TC Kline double adjustable Konis and it's stiff, but the ride is still better than most JDM set-ups.

Oem rates are
314/342 for 03/04
314/427 for 04.5+

Ask yourself why you would need to go up to 690/690

Plus,..... DO NOT RUN THEM WITH ANY OEM SHOCK OF ANY KIND!!! Saying you can is flat out wrong.

Koni rebound adjustable sport shocks don't have enough control range to run with them and Tokico D-specs have a 450lbs rate cap so those are out as well.

The Tc Kline shocks were made for them and the only shocks that should be used. Koni SA's can be revalved, but going with a product that was designed from the start is the best thing. They still might be on a group buy for $1000. Truechoice phase III and IV shocks would need to be revalved to run with the springs just to say it since they were R&D for 500/425 rates, course the Phase IV units would give you additional bump travel.
