Can anyone tell me the manufacturers that produce an in car adjustable suspension for the Z. I already did a search and couldn't find anything.

 

What are you looking to adjust the coilover dampeners or the ride height? If ride height are you just looking for airbags or something that will keep up with the suspension under hard cornering loads..
There are a number of companies that manufacture either one or both.

I personally use a TEIN setup with EDFC for my dampeners and am looking into a Top Secret ride height adjustment system.

 

that must be big $$$$.

 

Can I dare ask why you would want this? Can't imagine keeping your corner weights correct on a system like this, and you camber would be all messed up at anything > 1" adjustment.
Now if I could have an in car camber adjustment - that would be the bomb!

 

Yep, looked into the Top Secret setup as well. It's called the "Roberuta Cup Kit" & it's definitely $$$$.

"Roberuta has enlisted us as one of the few companies to carry their unique products. Roberuta is famous from their Ferrari products in Japan. Roberuta Cup Kits are an electronically controlled height adjustable system that fits directly on top of your coilover. They are NOT hydraulics or airbags. They do NOT suffer from the same limitations and performance reducing issues as hydraulic systems or air bags. We use the complete system on several of our competition vehicles.

Imagine being able to raise or lower your vehicle's ride height at the touch of a button. Steep driveways, flatbed tow trucks, and jacking up your vehicle with a standard jack all become effortless. Lowering your vehicle to the absolute maximum for your next car show is possible without readjusting your coilover at the show. Life becomes simpler and you can spend more time enjoying your vehicle."

 

That looks like a air bag system, same question - why would you want this?

 

Very nice and a little pricey. If you have a body kit like Do-Luck, you know the appeal of this system.

 

MoodDude: Ron is correct. My car is so freaking low as to be a royal pain in the butt... And I do not mean I have it dropped to the ground. I have actually had to raise my suspension 3 times to date (after dropping it about -.8" to start) If you see pictures of my car you can seen a very big gap between the tire and wheel well. My problem is the extended down-pipe, 3" dual exhaust, mid mufflers and surge tank in the rear. I scrape everything when I try to go over a speed bump (sideways or otherwise) I even crawl over it and can hear my pipes scraping as I go...

So, if I could have a setup that allows me to drive where the car is at a normal height with alignment and corner balancing, then when at car shows drop it for that show winning look, and later raise it to clear those stupid bumps and trailer ramps. That would be perfect.

I also asked about the effect on suspension and they have told me Ferrari uses this in Japan to allow them to negotiate all of the obstacles I have mentioned above and still race. This is of course not on the professional, but the privately owned enthusiasts rides. They have also told me this is not an airbag system. From what I can gather yes it uses a compressor and tank, but only as a means of powering actuators in the cups. Again I am not 100% sure.


GTNPU: that is cool you have seen this. I don't know too many people who have. I only know of one place that has installed this on a Z and he said it was a PITA... I have gotten quotes from the distributor and when I get the engine build done, I will be purchasing at least the front setup to help solve my height problems.

FYI, it fits right over my TEIN EDFC and will allow me to retain the ability to adjust my dampeners along with ride height from inside the car

 

Funny, I was also considering doing that with the TEIN EDFC or the Tanabe TEAS. I think ZEAL will be coming out with a similar system as well.

 

Cool,

I will be in the market in about 2 - 3 months for something like this... I will keep an eye out.

Thanks

 

I heard that Zeal was going to have an EDFC type of unit. Man im waitin on that. If they have the height adjustment then i think i'll need to save up some more money.

 

So will you selling your Tein w/EDFC when you get these?

Still don't believe this will not affect your Camber, but I guess if you have a show car - who cares about the performance.

I have dropped my car by 1" and don't have any problems going over speed bumps, but I do try to miss them.

 

In theory, you would set your car up at the height that you would like to do your normal driving on & correct the camber there. These (for now) would essentially just slam your car for shows & lift them to go up steep driveways/bumps. After the show or once you're over the driveway/bump, then you can put it back to your previous setting for driving. Like what has been mentioned already, it's mainly to avoid any damage to your car unlike standard suspension setups, you are pretty much SOL if you are forced to go up a steep driveway, bump, or ramp.

 

thats a pretty pimp system... that a kit specifically for the z? or can it be altered to fit other vehicles?

 

No I would not be selling my TEIN, this would fit on top of the coilover and EDFC controls..

GTNPU Z is correct. You set your suspension tune for how you would normally drive the car (a specified height, camber, and toe. Then you would only change the ride height for shows or for short distances like loading ramps, speed bumps, steep driveways etc..

I definitely care about performance, otherwise I would not be spending so much on the Tein, EDFC or other engine, exhaust and drivetrain mods. I have to assume if it is good enough for Ferrari, then it should be sufficient for my handling needs.

 

I would believe this system would work if it possitively hold the car on one height (like a Acme thread). I guess I need to learn exactly how it moves the car up and down, just won't want them to move when I am on a road coarse going 120 mph around a corner!!
I know you said that Ferrari uses a similar system, but like you said, it is a different system. Now, could we buy the Ferrari set up?

 

Brent, how far between your tire wall to the fender?

 

I agree, I have to say I have not gotten a straight answer yet. I will have to go up to Frederick Nissan and ask Gene exactly how it works in the next month or so.

I think if you buy the complete Roberuta setup that is what Ferrari uses. But again not sure.


Bubble: Not a lot, in fact I am rubbing now when I hit any type of minor dips especially when I am turning. I am having the fenders rolled and stretched a little next week before I drive the car to Florida from Maryland.

I do not have access to my pictures while in the office, but here are some from AAM

And you can see I have raised the front, but the backs are rubbing pretty bad. I can get a finger in the back I guess but that is about it really.

interesting..base on the picture there, i think you have more gap than i do and i don't have problem with rubbing and i haven't roll my fender either. I can't even get my pinky finger in. Like half of it. Would the offset of the wheel playing the different here?

 

Man that is pricey as hell
