Hello all.,

a few days ago there was a guy on here claiming to have a stock camaro on 20's that beat a new supercharged mustang. now I know that's crazy, but you all implied that the 20' rims would have made the car slower.. Why is that, considering the Bugatti has 20 and 21 inch rims?

Oh my God....you should stand back and read again the idiotic post you just have come up with. First, how much HP the Bugatti has, not to mention aerodynamics, weight distribution and suspension setup. Please....get a clue. Get a ******* clue.

Putting it a bit nicer lol, if u have a car with 20" rims go to 24" rims, it WILL get slower.

Cuz im lazy-

Sorry, Im too honest. LOL!

thanks for that warm reception Mr. Chaman. Looks like your trans am has rims larger that the factory 17"ers. If I am correct, did you lose speed by switching to larger rims?

I didn't mean that the camaro should be anywhere near as fast as the veyron, I just meant why does putting larger rims on a vehicle necessarily mean it will go slower? increased rotational mass?

Ya he can be a real dick The larger the wheel, the more rotating mass you have to overcome. Heavy wheels slow your car down and can actually effect your cars performance more then say an extra 50-100lbs in the trunk. The wheels are part of the drive train, the engine has to spin the extra weight. At the same time a 17" rim with a smaller side wall will corner better then a lighter 15 with a big sidewall. Depends on what your looking for, lots of ******** on this site ( including me )... if your a noob its gonna get worse! LOL , Cool pic BTY, Slys the ****!

Thanks Sweet C5. I know it was a noob question but I just wanted to know for sure. I haven't posted much on here but I've done a lot of reading and one thing I've learned is that you have to show respect and have thick skin on LS1tech!

And yeah Sly's the **** lol

it also depends on the wheel.. just because its a 20in doesnt mean its heavier. i have lightwheight 20's on my V and the handling has improved drasticlly, plus with 500rwhp i dont think my wheels are slowing me down much. And those camaros come stock with 20's FYI

Arctic

5th gens might, but 4th gens didnt come stock with 20's

im only assuming it was a newer one..never saw the original thread

Arctic

ok, it was a 4th gen, guy was saying he beat a supercharged 5.0 with his stock 4th gen running 20's. it was a whole bunch of win in that thread

homerz28

if a 5th gen can spin a 20" just fine, i dont see why a fourth gen would have that much of a harder time doing it.. especially since i hear rumors that an auto 5th gen can dyno less than a stick 4th gen.... ?

Arctic

its not just about spinning em. the more weight the motor has to spin the less power you will make. its like pushing a 50lb box up a hill vs pushing a 75lb box up the same hill. yeah you can get em both up the hill, but it takes more effort to get the 75lb box up the hill.

homerz28

I understand that. But since so many cars these days are coming with 20" rims stock (many of which make less horsepower and torque than an LS1) why was that guy laughed off the stage for having 20" rims? Could it make THAT much of a difference?

sweetC5

YES... they do make lighter 20s but there NOT light. My car came with 20s and they look nice, but a light set of 18" would take a good .2 off my 1/4 as is. I would like to get a light set of 20s and a 18" dr setup on the rear for the track. Personally I dont think 20s look right on a 4th gen anyway, 18 is as big as I would go for alot of reasons!

A taller wheel will add height to the total tire height, which means if you start off with say, a 3.42 gear, it will drop...to what exactly depends on the exact tire height.

Hey Homer...btw..welcome (if you are a noob). Secondly, Don't ever feel ashamed or allow other people to put you down for asking for information about a topic that you are not familiar with. There is no shame in asking!
Most people who would not ask a question usually have to much of an ego and afraid of what other people might thing of them. People such as those will usually be the ones that will continue to say the wrong things or make the same mistakes over and over again. I give you repect for asking that question on a car forum such as LS1Tech. Good for you man!

homerz28

Hey Mach32V, thanks for that. I guess I should have posted this in the "Noob" section, but since I was referencing a story that was just in here, I posted it here. And you seem real cool for a Ford man Haha
