Vogtland Lowering Springs
 

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?

About 10 years ago I had a 525i that was few inches of the ground - whole car. I know very well how to recognize suspicious ramps and how to go diagonally in order to minimize scraping, don't worry. Plus, I believe it's really common sense not to go straight whenever you're clearing such obstacles. So yes, I do go at an angle, 45° if possible.

According to OptionZero, "It a you problem, stop driving like an idiot". I disagree with him, I had the same problem.

I don't want to sound like an *******, but that's just an idiotic approach.
I'm not saying I'm the best driver on the road, but I've long ago memorized every pothole and bump in the road, if not for driving a car, it's because I do a lot of road cycling.

Regarding driving style, I'm a normal driver, keeping the speed limit, not doing anything crazy. Our roads in Slovenia are OK, I'd even go so far as to say they're not bad at all actually. I went over the speed bumps as well, if I stop the car and go very easy - no scraping. I did notice on some that I get the "front spat flap" scrape (not sure if that's the correct name of that part) - and there I have just 3 inches of clearance. So my first question is - can I just remove them, is there any specific function to it?

Otherwise I'll go to the garage todaay and measure clearance all around (bumper lip, front spat, sideskirts, engine undertray, exhaust pipes which go around the diff). I already checked the "usual" clearances for various other cars which are supposed to be fairly usable so that I'll know whether I'm in the idioticly low zone or I'm still in the somewhat normal zone.

I still have concerns about rubbing if I want to put spacers all around. The rear looks like it could handle 15-20mm spacers, but in the front the wheel arch plastics seem like they are just super close to the wheel - I can't imagine not scraping it in case of bottoming out (or just being close to bottoming out).

Sounds like you need an air suspension.

there's no reason to remove those spats. Just let them scrape. They give you an audible cue for places to avoid. Either they will wear down over time, or you'll learn to drive in a way that doesn't scrape them.
Grabbing a dremel and removing them won't hurt anything, but again, there's not much reason to remove them.
