High speed ride now getting dangerous

hopefully there is a unlimited Autobahn in the near.

Look forward to hearing your comments, thanks

personaly mines coilovers are way to overpriced. i would stay away!

they are a great set of gear, but not needed showing that there are other cheaper alternatives that are just as good if not some better, and even some that are just as good that dont cost as much.

mines knows what they are talking about, but first and formost they are sales people.

are a really nice set. AUTECH TSUKADA ATTKD's Web Site made a custom set for the R35 ATTKD Suspension and Tuning

Ohlins Suspension for Nissan GT-R garage saurus say alot of good things about this setup, and its much cheaper!

the Quantum T5-RS are really nice aswell. alot of people want, really want these. they are quantums "standard" coil over.

these are all well under the 1mil yen mark and its not like they dont know what they are talking about. mines is great and has alot of money to do research. mines is great and i wont say anything bad about them. its just that they are expensive compaired to others and others are just as good but at a differnt cost.

The VX-ROM is properly programmed to take into account the removal of the limiter.

They have close ties with Nissan and wouldn't do something as stupid as simply removing the limiter without considering and adjusting all the other parameters. That's something you'd expect from a budget piggy back device that you have to hack into the wiring loom.

Kanzen, I understand we've discuss this that if we're to go ESTA suspension by mines, we'll be always stuck in the R mode. And this high speed nervousness will all be solved. And the ride height will be lowered 40/20mm. Now the question is will the ride comfort improve or stay the same or worse off? I just dont seem to understand how can lowering a height of further up front by 40mm can improve the right. Surely it will be even stifter and less damping? I could be very wrong here. That is my only concern.

And this is not related, supposely the checklight came on, I assume Mines engineer will be able to reset it? Also could you check GTR Mods thread with the poll one? Theres a question there for you regarding Mines carbon spoiler.

[JackyN]

Even you reset it the light will come back on. I think the best way is talk to mine's and do something on the ecu but i'm not sure if mine's will do it because they play safe!

Reading feedback from Tokyogtr is really great. Appreciate him taking time and effort to post such useful information...

But FIRST, i think you should really drive your car before you start going amok... Maybe its not as bad as you think? so it bounce alittle on high speed.. but i dun think its a dire straights situation where by you WILL crash right? I mean Tokyogtr is still sharing his vid and all..

So its a hairy situation for him because he did not expect the additonal bonuce.. but now that he knows.. he will be ready..

likewise for the rest...

just my 2c worth

Very much noted on your points King. I am not at all that too concern of the harsh ride actually but I am rather concerned regarding the nervouness above 180km/h. I travel around 30km to work everyday and there is a stretch of perfect straight road with high speed bend that last around 10 km of length which my 65AMG always took it over 250km/h in many instances. With a GTR, I am sure i will be pushign around the same speed. Thats why i'm rather nervous. But true, I should just shutup and drive the car first and feel it. Hopefully my car doesn't show those kind of unwanted traits.

My car kept getting delayed (doesn't everybody?) Now I am surely to get it by late next week. We'll see then. I'm just doing some pre-emptive knowledge here

[Kanzen]

In that case could you check how extensive are the geometry/allignments to be changed? And what kind allignment machines are needed? Will any series of Hunter works? And the Mines engineer will decide what kind of geometry to put set in for you right? I hope I dont have to give any inputs since I have no idea what suspension settings are or what my preference drivings are.

Also with ESTA its said to reduce front by 40mm and back by 20mm, that front drop is too much for me. As in I think i'll scrap the carbon lip all over the road and become the world first GTR municipal sweeper Is there a way to lower it less? Perhaps like 15mm front and 10mm back and achieve the same stability results? Malaysia roads have lots of illogical hump/bumps.

The last time we spoke on Email you said you were now going to talk to Mine's through a friend, so I would have expected all your questions to be answered by now.

I'm happy to answer general queries, but you have a number of questions which are specific to your car and as you are already in discussion with them then you should also ask these questions too.

Comfort and performance is always a trade off. You need to detail your requirements and then discuss the spring rates and settings to ensure you get what you want.

[GTRAM]

SwissFrank . Apologies if you're just "blag surfing" and having a bit of fun in which case just ignore me. If not here's my two penneths' worth.

Many cars with 4wd systems take years to find the right balance of tyre and a lack of tramlining at low speeds, never mind at high speeds. (Mostly Haldex based). Once they have the right Michelin tyres they are fine. This will happen here too.

"Unsprung weight" is more of a problem for the ride comfort of passengers in vehicles on rails (trains) where there is no choice of route, whereas with a free vehicle the heavier and faster the spinning wheels the greater its straight line stability (Why do you fall of a bicycle if its not moving etc...) . If Tokyogtr is concerned at cornering at 180+ then weight is a concern but unsprung weight is still less of an issue than overall weight.

Always happy to learn if I missed a lesson.

I've lower 20mm front and 25mm rear. The roads in HK are not too good and i've laready scratch the front lip a little so don't go any lower than this. The rear is higher than the front so you should lower more on the rear not the front.

[Phoenix]

This thread was a good conversation to have..thanks Tokyo.

We all have lots of fine tuning to do to arrive at our particular interest for this vehicle. As always, appreciate your contribution.

[dec55]

I wonder if the US version will have this problem, it's Speed limiter is going to be
set higher than the Japan version...so I imagine high speeds for the US version
will be more stable in this sense...

Congrats on you gorgeous GTR...hope you get the high speed performance
fixed....

My first GTR drivingexperience:

Yesterday i could do a 1 hour testdrive in the new GTR

I dont need to write about the good things,just maybe the from my point of view "bad" things.

The suspension is very stiff when going normal speeds,you can really feel every small bump in the road. It did feel very nervous on changing road conditions(b-roads with changing tarmac surfaces),but i think thats just till you get used to it,i mean i had just around 1 hour to drive it

The car was still limited,but driving with 180km/h max didn´t make me feel im "unsafe" in it,it was more boring,as the car was very good balanced and you could easily do this with just one hand on the steeringwheel on a not super flat road. I was thinking,the faster you go,the better it works....

The car had the Bridgestones on,no mods made to it yet.

I would really like to take it to higher speeds,but thats at the moment not possible due to the speedlimiter.

Steering felt great,very good responce,brakes are great......awesome car,can´t wait to get mine next year
