Hi everybody.

First, sorry for my english, Iīm from Spain

Second, Iīve been trying to search for this question and I have been reading theads for 45 minutes, and I donīt have any idea what to do.

After reading all of that information, my question:

I want to lower my 350z w/o hurting factory shocks. I donīt want to change my shocks soon, and I donīt want to break them.

I have read about two. Which one do I choose?


1. Swift Sport Springs 03-06 Nissan 350Z


2. Hotchkis Sport Coil Springs

3. Any other suggestion.


I hope you can help me. Thank you very much!!!!

 

No matter what, lowering your car on stock shocks will soften them up and eventually you'll have to swap them out. I say instead of the TVS1, go with a set of springs only and get some tokico's or koni yellow's. You'll be much happier and you can always add the sway bars later.

 

Thank you for your answer.

I suppose that tokico's or koni yellow's are shocks.

What are the sway bars for?

 

the springs are all going to be pretty similar, lots like tanabe gf210, I personally have Eibach and so far they are nice. But bugsbunny is rirght eventually you will have to replace your strut.

 

Out of those 2 options of springs you are saying i would go with the Hotchkis. Another suggestion i would say Tanabe but I'm biased Depending on how much punishment the shocks get once you drop it they should last you quite a while before giving out.

 

03-04, I would go with Hotchkis. 04.5'+ I would, and did, go with RS-R's (Ti2000)

The reason I put different names with different model years is the spring rates. The Hotchkis rates are pretty close to the 03-04 stock spring rates and the RS-R's are close to the 05+ rates (although I'm not sure about the 07 stock spring rates.)

 

swift sport springs are your best bet. im pretty sure they don't go lower then an inch. plus they are a reputable (sp?) company for making springs and coilover springs.

 

Neither one of your spring choices are that much stiffer then the oem springs or drop the car a great deal as to cause the oem shocks to wear out. You have made two great choices in linear springs. The Swift springs are more expensive then the Hotchkis springs, you'll need to be able to justify their cost. It should be about the right choice for the right reason's, not a popularity contest where well thought out choices aren't alway's what other's do.

Just to say it, it's my understanding that all european deliver 350Z's have the revised suspension, so I can't recommend replacing the shocks because you have a U.S. 2003 or 2004 car.

 

The hotchkis springs are very popular and a lot of members run them w/o replacing the shocks. Also because of the subtle drop, most people get away w/o needing camber kits. I'm actually getting my Hotchkis installed next weekend.

 

Sorry. I forgot to say that my Z is a 2005+ Z (300 hp). Does this matter? I mean, is there any difference between 280īs and 300 hpīs suspension?

 

No difference between 2005 and 2007. In the U.S. their is a difference between 2003/2004 and 2005/2007. It is my understanding that all european delivery 350Z's ride on the same suspension as our 2005/2007 cars. Of course knowing shock part numbers would be the ultimate test. In any event knowing you have a 2005 means you have decent factory shocks.

 

go swift.

 

Are you saying that all z's that were delivered to the US ride on the same suspension from 2003 thru 2007 oppossed to z's sent to other countries? In the first sentence you say their is a difference btw 2003/2004 and 2005/2007 I'm confused.I misunderstood your statement know need to explain I understand now

 

Because I wouldn't want you or anyone else to be confused, I'll clarify.

It is my understanding that all european deliver 350Z's ride on the same suspension, the one we know here as the "revised" suspension.

The difference between suspensions 03/04 vs 05/07 applies only to USDM production and was not ment to confuse the issue about european 350Z's.

USDM 350Z's for model years 2003 and 2004 have the original suspenison. Midway into 2004, Nissan did a running change where they revised the suspenion. This revision features new shocks with less compression dampning and more rebound control. Rear shock dustshield/bumpstops were also redesigned. Rear spring rates were increased 25% from 342lbs to 427lbs. And front sway bar strenth was upped 17% courtesy of thicker walls in their hollow construction.
