mechanics behind scissors doors modification?
Sorry for the mix-up. I thought for sure that hatchback meant sunroof. Anyway, I haven't seen the scissor door kit that comes with any kind of pump. The kits are expensive because the machines hinge piece is difficult to mass produce for various models and is (apparently) exceptionally well engineered. Somebody needs to get paid.

rwd requires downforce on the rear wheels at high speeds, more than a fwd car.
chmercer wrote:hmm. why would a street driven 240 need the additional downforce that would be added from a home installed, 50 dollar aluminum bookshelf? i dont see many 240s spinning their rear tires on the highway, they seem to have enough load to keep it on the ground. i guess if you like understeering all over the place at high speeds it would be a good idea to put a big ghetto wing on your car. who needs traction on the front wheels anyway? its a rear wheel drive car right? you only need the drive wheels touching the pavment, duh.
wow, you did a great job sounding like an idiot there, but good attempt at humor. in case you missed it, i was talking about a high speed car that i was theoretically building, not a street car. i also was not talking about a $50 cheap imitation spoiler.a big aluminum wing on the back makes you "understeer all over the place"??? what are you talking about??? if you put a wing on the back of your car for downforce on the rear, you better have sense enough to put something on the front also. and i really doubt that at high speeds you would even have the chance to "understeer all over the place" before you would crash and die.who's talking about a "big ghetto wing"??you only need the drive wheels touching the pavement? was that supposed to be some lame attempt at humor??
i think you're the one who needs to read up on aerodynamics if you truly think that a rear spoiler does nothing for a high speed car. i also think you should re-read my previous posts and understand what was intended before you try to attack something that is not there.

why? why would a rear wheel drive car need more downforce on the rear wheels than a front wheel drive car? do you understand weight shift at all? that is such an igornant statment.spitz7985 wrote:rwd requires downforce on the rear wheels at high speeds, more than a fwd car.
do all the other hopefuls a favor and delete your stupid post so that noone thinks that your stupid babbling is actually correct information.
chmercer wrote:why? why would a rear wheel drive car need more downforce on the rear wheels than a front wheel drive car?
i do understand weight shift. reading your very angry, insulting post has inspired me to research more into fwd high speed vehicle dynamics, which is when i realized that my pre-concieved notions were incorrect. i admit my wrongfulness on the topic of fwd high speed dynamics.
however, back to what was originally intended by my post in this thread- the term rice has come to describe too many types of modifications. i think if someone can go out to home depot and make his own scissors door modification for $40, more power to him as long as it looks clean. there is nothing rice about ingenuity and creativity. back off, guys.
the comment about the wing was to prove a point.
if you arent 100% sure of somthing, dont act like it. it gives people a bad impression, which is what probably prompted ivoryj30t's comment of "you sir are a moron". even if you are pretty sure you are correct, just dont act like a genious, that way there is no way you can dig yourself into a hole. sorry for being angry earlier, done arguing now

Funny story time: my friend has a cat that they started calling Shortbus, they call it Shortbus for one really good reason. If you hold it up to a door frame, it'll grab it with it's front claws and hang, it's too scared to just drop so it hangs there until you lift it up off the door frame and set it down
Unfortunately I think Shortbus has gotten smarter because he wont do it for me anymore

it takes little prompting to get a comment out of me.
especially when your trying to tell a person who works on cars for a LIVING [auto mechanic, electrician, tow truck driver] that he doesnt know what hes talking about.
ok, heres a prime example. how big is the rear wing on the Mercedes Benz S55 AMG, and the Ferrari 575M?
oh, i guess the engineers must have forgotten how important wings are. why dont you call them up and remind them.
Stop bickering..
I like the following wing:
http://cgi.ebay.com/ebaymotors...33638
"Ricey" or not.. looks good w/ the lights and all.. Anywho.. there are tons of body mods that look good to some people, and look horrid to others.. the point is it's their car and they can do what they like with it.. These forums are designed to help everyone in the nissan/infiniti community; we can all take some heat for doing something not widely accepted, and there is no way you can ever do anything EVERYONE will like but there is no need to sit here and write two pages of *****y comments to each other.. So maybe someone was wrong, or maybe they misunderstood something.. we can all learn new things and you can correct someone without sounding like a total jackass.
Anywho, look at the following picture and laugh because if there is more fighting I shall run over you with my poorly painted vehicle [I think it's macco!]

i'm sorry dude, but being an auto mechanic/tow truck driver gives you zero credibility when it comes to high speed racing. my uncle is a nissan tech, has been for 30 years, he knows jack about racing.
there are different kinds of high speed cars, requiring different size/shape wings. some have to take turns, others just go straight or run an oval.. the original comment of "if i were to build a high speed car, it would have a giant wing..." and its purpose was to challenenge people who call everything rice to reconsider their quick judgment. so back off. i don't even know what you're trying to prove. that high speed cars don't have big wings? whatever. i could give a hundred examples. who cares? like i said earlier, you're attacking something that is not there.

i started getting out of my league when the conversation/arguement/discussion/whatever shifted to fwd vs rwd high speed dynamics. i have done research into high speed dynamics, they happen to be all rwd cars and i took what my friends said about fwd cars as true. when ivory called me a moron, or whatever, that was uncalled for. i had said nothing untrue at that point.
spitz7985 wrote:high speed cars don't have big wings? whatever. i could give a hundred examples.
And there are a hundred other examples that say otherwise, for example: (A bonneville top speed car that undoubtedly, goes very fast)Or: (No giant wing on the back of that bad boy for downforce and it does 470mph)Or: (That one is Bob Norwoods 288-GTO that went 267 mph at Bonneville)
I guess my point is that whether it has a wing or not is not solely based upon top speed alone but on several other factors, an important one of which is how the REST of the body is designed and what kind of racing it will be doing.
fyi: i heard that lambo doors are scissors-type because the doors would swing out too far to be practical in say, a parking ramp. a lot of low-roofline coupe suffer from this. ex. new celica's. damn those doors are sooo long. but if they made them shorter, entry/egress would be impossible.not that anyone remembers that this was about lambo doors.cheers-Enzo

congradulations!!!! you the proud new owner of a deeper hole!!!
ok, instead of me flying off the handle on this one, im just going to stop arguing with you. this is obviously going nowhere, and your just going to continue to tout what you consider "right" no matter how wrong you are, and you refuse to be reasoned with.
I dont claim to know everything, but if theres something i dont know im open to learn. your just completely seadfast in your ignorant statements, and theres no getting through to you.
you fail to back your statements up with proven facts, and since i disapprove of rear wings, i "know nothing about high speed stability" in your mind.
ok, i aknowledge that wings have their place, but they do not serve nearly the purpose that you think they do. and with mordern technology, there nearly obsolete.

Back to the door question, I have seen this kit on a 95 mitsu eclipse. The door opens a few inches like normal then you just lift up on it and the hinge pushes the door back then up. Pretty trick piece and it bolted on the car in the same loction as the stock hinges.. When you lower the door swings down and a little forward kinda like a slight arch and ends up open a few inches you just push the door shut on the factory strikers.....
Just buy the kit, copy the hinge, send kit back. There a simple solution to the 1500 dollar problem.
As for the wing, why again doesnt a FWD top speed car need down force on the rear wheels???? Maybee to push the entire car down to the road rember they are light in the rear end. RWD is the same purpose, the faster you go the more weight is pushed on the front of the car, and the rear more times than not produces lift. Now imagine a FWD car with oh 60/40 weight distrubution. Going some where over 150 the back end becomes very light due to the lift of the car, so a wing will keep it planted. RWD the same thing happens but at a much higher speed.
But on a street car going 70-80 on the interstate it does nothing but make everyone else say, "hey look at the grocery cart driving down the road, or look he brought his own pick nic table to the party.
Another thing to consider if those super go fast wings were even going to provide down force, do you think the rear trunk lid sheepmetal that they screw them too would be doing much of anything at all???
things that make yo go HMMM!!!!!
:rolleyes

how did lambo doors turn into trunklid wings talk. If u wanted a wing that even did any good at all instead of just adding drag, like 99 percent of the ones u see, will cost u at least 2 grand and will mainly just stop the lift that the rear end of the car makes. AND furthermore lambo doors arent all that riced out id say because they dont really hurt the cars performance at all and do have some function i suppose.
