Damn so if someone on here ways 180lbs and gains some wieght and hits 200lbs they are screwed when driving on the freeway. How will they ever keep up with traffic after gaining that much wait?

We all need to stop eating fast food so we lose weight and get the full potential of our RACE CARS.

I think there are 2 key points to this debate people must remember. I'm sure they were mentioned here somewhere, but I just wanted to highlight them.

1.) Unsprung weight is different than sprung weight. Adding weight to your wheels is VERY different than adding weight to the rest of the car. I'm not sure the conversion, but to get you thinking about it, it may be that for every 1 lb of weight added to the wheels, its like adding 10 lbs to the car.

2.) Most aftermarket wheels are lightweight. Therefore someone who puts 19's on their car could actualy have lighter wheels than stock 17's, and someone who puts 20's on their car could actually have lighter wheels than stock 18's.

There is not one single 20" rim that is lighter than the oem wheels. So sorry but even forged volks weigh in at about the same as oem. There are a few 19" rims that are lighter than oem but most true lightweight wheels start at 18" and go down to 15". There are just types of enthusiars. People that do everything for looks (like the guy with lcd's in his headrests lol) or people who pay to put performance in their car (me nano etc). I also do mods for looks but they offer performance as well. I think performance is what makes a car look cool to begin with.

That is absolutely not true. In fact if the company doesnt list the weight of the wheel assume the absolute worst. I think you would be very surprised how much some of these expensive wheels weigh, i know i was when i bought my first set of rims on my old cobra doh!

3) moment of inertia. As I said...

the bigger the diameter, the more "effort" is required to "move" the wheel... exponentially.

17" 20lbs wheel does not require the same force to "move" as a 20" 20lbs wheel, even though they weight exactly the same the 20" wheel requires MUCH more force to be "moved".

someone should get 22" rims and wrap a bunch of rubber bands around them for tires

When I was typing that, I was thinking about all the wheels I've been looking at. I didn't even think about all the chrome wheels out there and such. Sorry, narrow viewing field with that one.

So, let me rephrase that by saying....some aftermarket wheels are lightweight....


Someone above said there is not one single 20" rim lighter than the oem's. I'm sure someone out there has a custom fabbed wheel that they made nice and light. Can I prove it...no...but I wouldn't make a statment saying there is NO 20" rim out there lighter than our stockers....I'm sure there is one out there somewhere.

Totally agree...but (know I don't know the answer to this, but maybe you do) what would be better....say a 17" rim that weighs 20 lbs or a 20" rim that weighs 15 lbs?

If that is a too exaggerated comparison how about a 17" rim that weighs 20 lbs and an 18" rim that weighs 18 lbs?

Just curious...

find me a 20" rim that weighs 15 lbs that isn't over $1000 per rim or some custom job


I think a 17" 20 lb rim and 18" 18 lb rim would be close to equal...

this debate will never end. SOOOOO...let stop and move on. Those that like 20", get 20". Those that don't like, don't be a hater. Just enjoy your 17". Peace out.

Man...this thing is still going???

Okay...I will have to agree that for "track" applications, the goal is to be as light as possible so that they can achieve the best time as possible around a track. So yes, you'd want to trim down as much extra fat off your car as possible. Now, for everyday driving...this simply goes out the window. You can only go so fast on the street & accelerate only so fast unless you are looking for trouble. Now, I can understand the "purist" point of view of keeping your car up to "track" specification on the street but it is not necessary unless you actually track your car on occasions. Don't you know that our cars at stock form have a lot of unecessary weight that's been added? I'm not here trying to say 20's are going to make your car any faster since most people, like myself, bought them for looks anyway. When the times comes that people like myself do track our cars, most will swap them out with the appropriate wheels & racing tires anyway. Now if you see someone trying to track a car with 20's, then that's a different story. I can see where you can get into a good debate there. One thing that people fail to bring up especially during discussions like these is that for every mod that you put that may potentially degrade the car's performance as in more weight, there is always something you can do to counter that. So if you put big wheels that take more effort to spinning, add a mod that will increase your torque. Like I said...this thing could go on forever. Since I'm sure some of you will still be here battling it out, you can also debate about the following topics which has no right or wrong answer as well :

13" BBK vs 14" BBK
Roadsters vs Coupe
NA vs FI
SC vs TT/ST
Bodykit vs No Bodykit

My favorite:
Brand A vs Brand B (i.e. Turbonetics vs APS, Injen vs JWT,...)

and the list goes on & on...

Have fun!!!

I would take these over any set of 20's out there, and they only weigh 19 pounds each. I am pretty sure this is lighter than 18 inch oem. wheels.http://weds.co.jp/products/wedssport/sa90forged_z.html

You guys have some AWESOME looking Z's!

"To each his own," is clearly something this person will never understand.

I guess i totaly ruined my supercharged Harley truck, by modding it, and slapping on 24's then huh?

Your car isnt a sportscar, its a truck. Therefore it really doesnt relate as truck handling is numb and plodding already. I mean yeah you just tied up a few of those horses you paid for and slowed it down but like i said, its a truck so who cares? Bling is important for you.

Your semi correct.. That was its last look, almost a year ago.. its completely different now, but still not complete. Im anti-bling now i guess you can say.

As for, "its just a truck, who cares" comment, do your homework on what an '03 Harley edition puts out, just say stock numbers, and I still have plenty of "horses" to run your Z... dont get me involved in the, "ill take you on a TRACK though" thing either.
