Ok, I found a new set of these springs for $99 shipped! So I couldn't pass that deal up for a 1.2" drop all around. But I looked in the lowering spring thread and didn't see anyone with these. Hope thats not bad lol. I just want to know if anyone else is lowered on these springs, if you had pictures and what do you think about them?


Thank you for any help
Justin

 

the eibach sportlines advertise the same drop

 

One of our sponsers will soon be here to tell you about your poor choice. And the sponsor will have a product that will better fit your needs. Price too low to mention of course.

 

I really dont think anyone could beat 99 bucks shipped. Yea I looked at the sportlines but I needed something now for IA and these fit my budget. If they aren't good I plan on switching out later on and going with koni yellow shock/ lower spring combo.

 

Dang 223 views and 2 people had something to say. That can't be good lol. Well I guess I'll test them and write a review about them. They make great coilovers so I would think there springs should be good too. I can't find any spring rates on them either so maybe I'll get that tested too.

 

"They make great coilovers"

With the above comment, I wouldn't be surprised if you bought them without knowing the spring rates. That would be a mistake.

Spring rate matters, you have several 1" - 1.2" drop choices on the market, a few of them I can eliminate based on spring rate alone.

The Ksport springs aren't a bad choice if you just want to drop the car. My roommate actually has them on his E46 and the ride is pretty good on OEM shocks. The car does handle a bit better as well.

Ksport GT lowering spring rates for the Z are around 5.5kg/mm in the front and 6.25kg/mm in the rear. Can't remember exact numbers right now, but I know that they're very close to what I listed.

 

VividRacing- Thank you very much, they should be here Friday or Saturday.

Gsedan35- Yea I'm not planning on tracking the Z so any spring rate more aggressive then stock and gives me the drop I want then the springs will be perfect. No I didn't know the rates thats why I asked.

 

shipping took forever but I finally got the springs in the mail on Thursday and put them on my car Friday.
Ride- The ride is very smooth yet a little stiffer than stock for sure.
Stance- The rear came down pretty nice already because I did the fronts last so jacking the car up from the front put all the weight on the rear for an hour. The front is still settling.

I will post pictures in a few days when it settles a little more. Is the darker silver on 03 not called silverstone? I was looking for touch up paint at auto zone and they had what I'm almost positive was my car color but called something else.

 

If you don't plan on tracking the car then why do you plan on getting Koni shocks / spring combo later?

Btw I had these exact springs on my maxima and THEY SUCKED!

 

I'm glad you're happy with your purchase! $99 shipped is a good price, but PM me next time. I'm sure we could have matched that.

Did you cut your bump stops?

 

But if vivid is correct with the springs he's mentioning, the springs are softer then oem. The Z does not have boat loads of shock stroke, dropping on less then oem spring stiffness is not a good idea. Not saying you'd want them sky high either.

Based on the numbers vivid gave.
308/350

For your sake, I hope those numbers are wrong.

But if your like all reviews posted on this site, I'm sure you'll say they're perfect and great. Until a few months from now you pull them and resell to get something that actually works. Sorry couldn't resist

 

Because I had koni yellows on my prelude and loved them. The stock shocks wont last long so I'll get the koni's. And if I don't end up liking the ksport springs I'll switch to sportlines.

 

post those pics

 

VividRacing,

PM Me. I'm looking for about a 1" drop all around, not really wanting any more but if you have something slightly more thats better priced/ better suited for a 03 350z let me know.
I'm wanting to stay close to 100 as well. No more than 150.
Get me a deal together and we`ll talk

 

I'll PM you shortly! Thanks!

 

vivid...

Care to define how you quantify "car does handle a bit better.."?
