Over here it is approx. £885 / year.

I'm with sarnie on this one. Doing this to rays wont look good.

I think you ll be in for a surprise

asl?

Not being a native English speaker has its advantages ... I dont understand any of the "name-cruelties" here mentionned

Following the Top Gear news yesterday ... Anyone here up for it?

Get a proxy dude

My god, what an awful color for a nice car. Is there room to store a purse? Oh, and a real sportscar (what this is supposed to be) shouldn't be a convertible Sarnie has made the right choice with his car methinks

In a way its naive to protest. Ok, there is a lot of taxes on fuel, but the problem is way bigger. "Developing" countries (read, places where you can still exploit people without being hassled with social legislation... ) like India and China are demanding more and more petrol/steel/..., and this wasnt the case 5-10 years ago. So more demand for the same product .... what are we going to do about that? There is only 1 solution, that is to find solutions to decrease our dependence on petrol. If you think about it it is just hallucinating, our entire society is built around it .... So what will we do when there is none left?

Thats nonsense. Its not because the car is bigger that it is per-se safer. Check some crash test reports for that. And i d rather have a car that crashes into another one, than have a car which gets underneath another one. Chances of survival with 2 ton on tour roof ....

You would be surprised I don't think Nissan has actually ever "approved" 3rd party manufacturer parts, like brakepads and so on, except for the ones they provide on the car when it leaves the factory. It is not because in reality it didn't happen (yet) that they could not pull it off if they wanted to.

And what about ESP/TC cutting in? I know its not supposed to work with wrong tyre sizes, but how does it react if you have a flat tyre and put one of those odd-sized "space-saver" wheels on temporarily? I had this on my TT and I cannot recall having had any TC problems whatsoever.

:scare: on lucky guy

ok, so about the tyre size? Anyone?

Well, you know that if you tamper with your engine, no matter how or what, you loose your warranty.... And it is not up to them to prove it did come from that modification, it's up to him to prove it didn't. The only pieces "allowed" are Nismo S tune, and only if installed by an authorized dealer.

btw, i prefer to stick to bridgestones because i have a verrry good price on them

Hi I just checked with Bridgestone for wintertyres, to put on the (non rays) standard alloys. I asked for 225/45/18 and 245/45/18 they got back to me and said that they dont have the rear tyre size, and that they verified and apparently a 235/50/18 also fits and they have that. Now my question, is this ok? And secondly, arent the standard alloys themselves the same width front and back (rays are 8 and 8.5" if i am not mistaken), so maybe i can just put 225/45/18 at the back too?? help

And of all of you who replied to this, how many of you already smoked some of "the green stuff"

in the latest edition of Moto Tech magazine they explain this drag stuff, and how it relates to acceleration and torque. I ll see tonight if i can be arsed to summarize it a bit

Well, stuff in real life is much more complex. My guess is that even the amount of text already written by Sarnie on this forum wouldn't be sufficient to contain the full explanation of how to tune a racing car. And that says it all methinks

It also depends on the gear ratios. The gears (and the wheels) determine the torque which is transfered to the street. Bigger wheels/longer gears mean more torque is needed to accelerate at a certain rate. Considering the weight, if I recall correctly there was some formula that states F = m*a. So the force is equal to mass times acceleration, which means a = F / m. So acceleration equals the amount of force divided by the mass of the object you are trying to accelerate. Now this is hugely simplified ofcourse, not taking into account tyre grip issues and all that stuff. Why this gear ratio stuff? Well thats the reason a diesel engine with X torque will never accelerate as well as a petrol engine with X torque. Because the rev range of the petrol engine is bigger you will be running in lower gears for the same speed in the petrol engine one, giving you extra acceleration potential. Of course when magazines compare accelerations in-gear at a certain speed usually the diesel is faster, but thats just because those tests are usually done in "petrol-unfriendly" ranges. (imagine doing an acceleration test from 50-80mph with the Z in 6th gear .... ) So, supposed you have the same car, the same weight, the same gearbox etc. And you put in an engine which gives high torque from 3000-6000 rpm, redlining at 7k rpm, or you put a diesel engine with the same amount of torque but which gives it from 2000-3500 rpm, redlining at 4.5k rpm the petrol one will be faster. I drove a friend's A3 once, 170hp and approx. the same torque as the Z, but i spent more time changing gears than accelerating it, 2000 rpm of powerband really isnt that much

Great ride for the Michelin tyres. Wonder what Rossi was thinking after the race Anyway, apart from that, quite boring to watch. Reminded me of F1

Yeah, but not THAT kind of lambo doors

Interesting to see salaries might be higher in London, but that gets easily canceled out with the cost of living.

I have it, not played it for 2 months though..... Ditto. Got PGR4 on the go atm, but not touched that for a couple of weeks. Need to get a games room, XB360 doesnt see much action being in the living room Mine neither, 360 wii and my PS3 were all in the living room and had no chance of getting the nod over shitty soaps Didn't that problem solve itself recently?
