Lowering Springs Comparisons

MaysEffect

I should clarify on this, by saying tuning bump rates should be done professionally. Using original sized bumpstops as a way to tune bump compression is not ideal, certainly with progressive rate springs.

Wow! Thanks, this is amazing! Anyone running Ti2000 RS-R Lowering Springs? I never heard of them.

What's up Z nation? Quick feedback guys.
Want to go w/ a "conservative" drop on my Z. Thinking of going w/ the ARK GT-F lowering springs along w/ rear camber arms and toe bolts.
With this "conservative" setup will I need spacers? And if so, what size spacers would you guys recommend?
Any other information or advice on this setup would be greatly appreciated.

FWIW Vogtland Lowering springs are listed as 1 inch drop front and 1 inch rear (according to the manufacturer) but in reality the fronts are probably between 1.5 and 2 inches. Spring rates are 314 front and 423 rear.

Why (as to why on earth I even care) and how I came to know this info is a long story. But that information comes directly from the manufacturer.

I had the Eibach Pro Kit Lowering Springs on my 2015 Mustang Ecoboost and I was a big fan of them. I'm interested in them with the Z because in part, familiarity but it's also the least aggressive drop listed on the first page.

Could someone using these comment on the drop and more importantly the handling/daily drive?

Other than alignment, is there any other work that I should expect or is it a straight swap.
Sorry for the new-b questions. I'm new to the car and there's so much info to sort through since this car's been around for 11 years.

Called H&R. They said they dont release the spring rate because the way they test the rating is different to others. They include the bump stop to their equation. They did say it is stiffer then OEM.

Do the stock OEM Nismo springs have a drop compared to stock non-Nismo springs?

I have OEM Nismo shocks/springs on the 2016 Nismo 370Z. Never touched it yet, and yes I did remove the spring blocks that come with the car during shipping lol.

I could measure the height of the car from the ground to the fender on all 4 corners. Maybe someone can measure their Base/Sport/Touring Z with stock suspension and we can compare it. I know it's not exact science, but it's better than nothing.

I'm also wondering if the stock Nismo suspension lowers the car as much the S-Tune suspension (the red springs and silver shocks that anyone can buy). Supposedly the S-Tune suspension lowers the car 10mm (0.4"). But I'm pretty sure they are comparing this to the stock Z suspension and not the Nismo edition one.

Just for reference:
S-Tune suspension product number is: E3110-1EA00

OEM Spring part numbers:

2015+ Nismo
Front: 54010-6GA1A
Rear: 55020-1EA0B

2009+ Base/Sport/Touring etc.
Front: 54010-6GA0A
Rear: 55020-6GA0A

Since these are different part numbers, the spring rates are going to be different. However I'm wondering whether the spring heights are different as well.

Whenever I get to measuring the cars height, I'll post it here.

I think this might be a suitable thread to post and ask this...

So I finally managed to get the Eibach Pro Lowering Kit installed. It's supposed to be a drop of 20/25mm, but it seems to me like quite a bit lower. Can anyone give me their opinion? Pic below.

Also now I seem to scrape on everything with the front wheel flaps - don't know what they're called, they're behind the bumper, in front of the wheels. Should I remove those?

I kept the stock shocks and the ride is quite a bit stiffer, although not horribly stiff.

Thanks for any input/opinions.

That looks about right to me! What size tires are you running

Stock tyres, 19/275/35 and 245/40.

The thing that confuses me are the flaps in front of the front wheels. I measured them today and they're about 3 inches off the ground which makes them scrape on everything. Did anyone remove them? I don't think there's any real purpose in having them.

Do you angle in when entering or existing driveways, or go straight in?
