Lowering Springs for an 08' EX35

Does anyone know of a company that makes lowering springs for an 08' EX35? Everyone seems to be stuck on this one. I took it to a local mod shop here in Houston, ASAA Racing, and they seemed to be stumped as well. Any ideas? I wonder if there are springs for other Infiniti or Nissan vehicles that will work on a EX35? Any ideas or suggestions?
 
I don't think there are any just yet. Could be a while before there is any in the market. Another option would be to recoil the stock springs. A shop with the proper tool can do this for you. Another maybe to look at maybe a the G35/G37 line and see if their springs are swappable with the EX.

That is an option too - LMS was gonna do that for me, before I got the Eibachs.
 
Again, thanks for the info. After reading up on this topic on the web, what is really the best way to lower a vehicle while preserving/improving ride quality and handling?

I've read that cutting the springs or just getting lowering springs would ruin the ride of the vehicle.

I've read that when lowering, you have to buy new shocks as well.

Which one is it? Please share your thoughts and opinions...
 
Lowered... never needed new shocks. Infiniti uses some beefy shocks to begin with.

As for RUINING the ride... you have to sacrifice some luxury for handling. In the case of the Eibach's, it is very stiff and you can feel bumps pretty easily, but handling takes a sharp turn in the positive direction :tongue:

I've never personally tried out H&Rs, but I've been tempted since they offer a much nicer ride. Probably not quite the same handling as the Eibachs, and that would be a very hard one to argue since they're obviously nowhere near as stiff as the Eibachs are, but still better than stock and give the lowered stance. I'd be willing to sacrifice a tiny bit of handling for a smoother ride, but I really REALLY don't want to do the labor of swapping from Eibachs to H&Rs.

Eibach must be bone jarringly rough then. H&R is definitely rougher than stock. I can't imagine how much rougher the Eibachs would be.

As Cube already mentioned, you can't get both of benefit. You either lose the luxury and get performance & looks or keep the luxury by just leaving the car alone.

Car looks much better when you don't have 4+ inches of wheel gap between the wheels and the fender. I thought lowering the FX was one of my favorite mods so far.
 
Correct you are Cube. Just got home from being out and about and since I got the EX and have been wanting to mod it, I seem to pay much more attention to detail when I see cars on the road. I saw two Porsche Cayennes on the road, a Cayenne S and a Cayenne Turbo, and they do have a lot of space between the tire and the body. You would think that if you paid that much money for Porsche, you would get a totally cool looking vehicle without having to mod it.
 
What's this I hear that when you lower a vehicle you also have to install a camber kit to ensure that the tires wear properly and evenly. Is this true?
 
It really depends on how low it goes. Usually you will not need a camber kit, but in some instances after a re-alignment some have gone over spec (but not by much). Not many on this board had to have a camber kit installed after lowering with either eibach's or H&R's. Look here for more detailed info if you have not already...

It's a slow morning at work so I decided to call all the major spring manufacturers (Eibach, H&R, and Tein) and unfortunately they DO NOT make springs for the vehicle as of yet. Eibach and H&R went as far as to tell me that it is not a vehicle even considered by their R&D Department for future testing and development.

Although, one of the technicians at Tein told me that they have looked into springs for the EX and he informed me that the EX is built on the same chassis as the Nissan 350Z and the Infiniti G35 Sedan/Coupe. He told me that fit would not be a problem due to vehicles sharing the same chassis, but since the load of the springs for the 350Z and G35 are specific to that vehicle, if I install them on the EX, there might be some "sagging" due to the increased weight of the EX.

What's the deal with "Sagging"? I take it that this is bad? Is there a way to correct the amount of sagging?
 
if the springs are ment to carry a 3,500 lb vehicle & you put them on a 4,300 lb vehicle it will be overloaded, that's what they ment by sag...

just because it's on the same platform don't mean there dirrectly interchangable either, the fx is actually on the same platform as well but doesn't share the exact same suspension, not saying it def isn't, just saying it might not be really... if it is I would try STOCK springs from the lighter car maybe, we used to lower v8 american cars by using 6cyl springs.. ...

Would it actually change the spring rating? ... Could sagging cause it to snap?
 
350Z with 4 fat people? YIKES! That's not good. Would the ride be rougher then and I guess a bit more sluggish as far as response?

If I buy the G35 springs and they don't ride well, can I go back to stock and have the original factory ride quality back?

If I don't find a solution, modding my EX will have to wait. GTO Dave, the illustration of the EX you made is still my goal and inspiration. Eventually, I will get there.
 
2007 G35 Sedan
Exterior Length: 187 in. Width: 69.8 in. Height: 57.2 in. Wheel Base: 112.2 in. Ground Clearance: 5.3 in. Curb Weight: 3538 lbs. Gross Weight: 4658 lbs.


2008 EX35
Exterior Length: 182.3 in. Width: 71 in. Height: 61.9 in. Wheel Base: 110.2 in. Ground Clearance: 6.5 in. Curb Weight: 3790 lbs. Gross Weight: 4866 lbs.


Looks like they are pretty similar in weight. 208 pounds (G35 sedan vs Ex35) Just 1 over weight person:marchmellow:

a bit hard to say, if the spring rate is too low then you'll hit the bump stops on heavy compression... not a good feeling really, I would start with stock g35 springs, prolly grab them real cheap on g35driver.com from somone who lowered & selling the old rather than throwing them out, should be able to get them really cheap...
