I've got a friend that get me a very good deal on a set of S-Tune Nismo coilovers, but I'm worried that they may not be quite agressive enough for the occasional recreational track days that I run.

I was originally was going to go with the Tein Flex w/ EDFC.

Anyone got any insight?

Weird, I could have sworn that I posted this in wheels, brakes tires and suspension...

Nobody?

I would probably do a lil more research. You should be able to get the spring rates fro the Nismo and comapre. In addition, I am sure another major manufacturer makes the coilovers for NISMO as most of their products. I am sure someone here may know who makes the CO for them!

Courtesy of the above sticky:

Nismo S-tune (twin tube construction, uses progressive springs, especially in rear)
350Z/G35 Coupe
Spring rates 448/504
Stiffer then oem by F+43% R+48%
Transfers +5% roll stiffness to rear

Reasearch really isn't the issue, I just want impressions from someone who has tracked them. My biggest concern is the progressive springs.

I haven't tracked the NISMO coilovers yet but really enjoy them on the street. Flat handling, lowered ride (not too low or still too high ... just right) not too stiff on rough roads. The car does wander on uneven pavement but that is from the alignment specs, rather than the coilovers.

It was the best spring available that gave more of a firmer ride with a conservative drop. I'm very pleased with my setup. Next spring when I have more time, I will be tracking the car at some Solo 2 events.

The disappointing aspect of the install was having to install front and rear camber kits with the NISMO springs. It was unexpected but still a recommended install option, as my prefered alignment specs were not achievable with the factory suspension arms and IMO not recommended without the camber kits for any lowering spring.

I am very surprise to hear that you need camber and toe kit for the Nismo suspension kit. I thought you don't need one if the drop is less then 1"? Can someone clearify this? I was consider it until your post

I think that I can skip the camber kit since I am actually looking for a little bit of negative camber, say -1--2 degrees. My street tires will suffer a bit, but my RA1s will like it.

How far out of spec were yours G35_6MT? Or did you just go ahead and have them done at the same time?

Also was the drop on the front about the same as the drop on the rears?

Thanks

The camber was way out on the front and rear to the tune about 4 to 5 degrees. Looked great but I wanted a more reasonable camber to have a balanced tire wear and performance. With the camber kits, I achieved the best of both worlds. I'll have to look up the specs again (filed) but I achieved the best comprimise to handling and tire wear. I have posted the results and perhaps a search will bring them up.

Suspension search

I didn't realize that it would put them that far out. I was thinking that I cold maybe live with -3, but -5 would just look funny. Guess I have to consider a camber kit.
