I see a lot of the 2nd gen owners running 20"s which weigh around 30lbs or more each (unless its forged). I was wondering if anyone knows how much slower your 0-60 and 1/4 mile would be with the bigger size wheels?

 

30 pounds more per wheel!?

 

lol its like 10 pounds more per wheel i don't feel dif..

 

I meant they weigh 30lbs each compared to ~22lb w/ the stock

 

LOL oh ok - that makes more sense... I was gonna be like dayyyyyyyyummmmmm!

 

so larger wheels and tires weigh more which will slow you down, so you know what this means, it's time to add alot more power, lol

 

well if its 8 more pounds a wheel then thats +32

now i weigh 189lbs and if i have a full tank of gas that would be around 120 more lbs but if my gf is in the car and she weighs 120 then thats added 140 to the originall weight, but now i only have half a tank of gas in my car and i have been on a diet then that would add around 172 more pounds subtract the original 20 each wheel would have been and divide it by e=mc2 then that should tally my total at around blah blah blah

oh wait i forgot were driving a four door sedan and not a race car so deedeedeedee basically this doesnt matter!!!




j/k

 

A few bolts on's can take care of everything too.

 

everyone has a different purpose for their car...just because you want to roll around on dubs and pump your music, doesn't mean everyone else wants to Some people actually like the "Sport" part of "Sport Sedan". Not to mention the 07 sedan runs mid 13's in the quarter

 

so how do you know that someone riding on the stock 18's will pull a faster 1/4 mile time than i will rolling on "dubs" and pumping my music?

were talking a difference of 25-32lbs here buddy....and if he weighs more than i do and has a couple more gallons of gas in his tank than i do then the diff is obsolete...... right?

Basically what im trying to say is when you own a 4 door sedan that weighs this much a couple extra punds WILL NOT make a difference (IE. 3625-3655)in 0-60 and 1/4 mile. Unless your doing serious light weight stages.

 

I doubt it makes much of a difference, but keep in mind that rotating weight is significantly more then carry weight. I'd say the 32lbs of total weight under spinning load is the equivalent of 300-400lbs of carry weight on the engine. it also adds that weight-stress to the brakes. it's much more then raw weight.

As an example, have you ever used a gyroscopic hand/forearm exerciser? an 8oz ball under high rotation has the equivalent of 50lbs of weight!

I ride a road bike and dropping a few grams on the wheel weight means you work less on every rotation of the wheel... it's not the weight, it's spinning weight.

 

adding 300-400lbs on the engine? No way!

What about this....you add more wheel but you subtract tire....so it evens out

there has to be someone on here thats a techy guru that can put this old argument down.

Im sure this argument has come up plenty of times on these car forums.

 

Just in case someone wanted to know, the stock 18" Sport wheels with the Bridgestone Potenza tires on my 07 G35S weigh in at about 51lbs x 4= 204lbs

My current wheels 20" Chrome Neeper Moxy wheels with Toyo T1R tires weigh in at about 67lbs x 4= 268lbs. A difference of 64 lbs. I'm not sure what that translates into performance loss because of the extra 64lbs but I guess it really depends on the type of wheels you're running. Like someone mentioned before if you're running forged wheels I'm sure they weigh less then my current wheels therefore the difference in weight will be a lot less.

 

rotational weight is NOT the same as 'regular' weight.

having wheels that are 10lbs heavier per corner will have a noticeable impact, where having a 40lb weight in your trunk will have no effect.

This is why some wheel manufactures strive sooo hard to make ultra light weight wheels.

I'd say the assessment of 10-12lb heavier wheels per corner being equal to 300-400lbs of 'regular' weight inside the car is probably fairy accurate.

Unsprung weight is the devil.

 

OK, so I exaggerated there , but my point is that it's more then raw weight. and the extra required effort is only during acceleration. but like I said.. it's really nothing. this thread is on part with the one where they guy wasn't getting a sunroof because it slows the car down.
