assuming he didn't lock up his brakes.

[lflkajfj12123]

BUT he wouldn't have to lock his brakes in the first place if the car didn't understeer with said better grip

[ILoveMyRHS13]

Or if he wasn't running 215/40s to be hellabroflush.

only thing wheels do for grip is make the tire wider or narrower, or dissapate heat. lateral friction has no effect on wheel weight. wheels don't rotate laterally.

a heavier wheel would be harder to lockup your breaks on.

I love rocket bunny, soooooooooo much.
Wish a company would make knock off or SOMETHING, 2g+ for fiberglass is not worth it on a track car : P

looooooooooool ok

go learn about unsprung mass and then come back and tell me that

[fckillerbee]

go learn about wheels. I know about laws in motion. Newton is my best friend. a front wheel only has friction (of the road (unless you want to include bearing friction)) acting as a force against it. when you turn left....it's the tires friction acting on the road surface....not the rim acting on the tire. while i agree a lighter wheel would be easier to stop...a heavier wheel would be harder to lockup.

turning a wheel left or right only acts upon the steering colums response.....that weight wouldn't justify a crash. there's inflation of the tire, tire depth, tread compound, inner casing of the tire, road surface, as well as brakes.....a wheels weight has very little to do with the response of the driver, momentum, and body roll of a vehicle, as well as outside environmental factors...

go read a fucking physics book. Better yet, go read physics essentals for dummies...it'll teach you the basics.

[fckillerbee]

and just for your amusement

In a ground vehicle with a suspension, the unsprung weight (or the unsprung mass) is the mass of the suspension, wheels or tracks (as applicable), and other components directly connected to them, rather than supported by the suspension. (The mass of the body and other components supported by the suspension is the sprung mass.) Unsprung weight includes the mass of components such as the wheel axles, wheel bearings, wheel hubs, tires, and a portion of the weight of driveshafts, springs, shock absorbers, and suspension links. Even if the vehicle's brakes are mounted outboard (i.e., within the wheel), their weight is still considered part of the unsprung weight.

Effects of Unsprung Weight
The unsprung weight of a wheel controls a trade-off between a wheel's bump-following ability and its vibration isolation. Bumps and surface imperfections in the road cause tire compression—which induces a force on the unsprung weight. The unsprung weight then responds to this force with movement of its own. The amount of movement, for short bumps, is inversely proportional to the weight - a lighter wheel which readily moves in response to road bumps will have more grip and more constant grip when tracking over an imperfect road. For this reason, lighter wheels are sought especially for high-performance applications. In contrast, a heavier wheel which moves less will not absorb as much vibration; the irregularities of the road surface will transfer to the cabin through the geometry of the suspension and hence ride quality and road noise are deteriorated. For longer bumps that the wheels follow, greater unsprung mass causes more energy to be absorbed by the wheels and makes the ride worse.

cause clearly....that amount of weight between one wheel and another...would determine this guy hitting a wall doing 80pmh.

sorry to go off topic, but here's a video of a zenki drifting.

[fckillerbee]

^^^ car looks good man.

[Persona]

Lol you guys are great.

[lflkajfj12123]

lol man you're a real idiot, the answer is right in front of you.

hey man i'm glad you know physics guess what i'm a senior in mechanical engineering at purdue so please get off your high horse

less unsprung mass means the less mass the spring has to act against when pushing the wheel back to the ground. the heavier the wheel the more momentum it has going UP and has a slower time to go back DOWN because the spring has to overcome the momentum. the wheel returning to the ground faster means more grip

you do understand how the basic concept of moment works right physics master?

anyways he was going around a corner fast and lost grip meaning he probably understeered into the light pole

please shut up now it was just a joke and you had to be totally gay about it

[kOOpA]

both of you go to your room without dessert.

[fckillerbee]

it's cool man. I did post it right there....cause it clearly showed the wheel had all the effect of it. I'm saying that the weight of the wheel....didn't have the major effect on it.

fucking high horse. just like engineering a car....there are more factors than just a wheel. I knew what you meant.....you just kept on adding to it.

oh hey...hows that horse over at purdue? senior right...means you do your homework....thanks. Say hi to Tim Sands for me ;x

[icedsole]

blitz 03's. he would have stayed on the road, no doubt.

This has to be the oldest joke on Zilvia since forever...

and you got all dumb about it and started arguing about physics because you don't understand unsprung mass very well

I can't tell if you're trying to diss me or not, mainly because it all reads as broken thoughts.

OT:

[Lukasss]

I passed up a great offer on some R33 wheels today...thats making me mad that i did so.

[lflkajfj12123]

I've owned two sets of mint R33 wheels and only to sell them both before getting a chance to mount them!

I regret it every day -___-

[Lukasss]

WEll, in that case, if i told you how much i was going to pay for them, id have to kill myself

LOL.

what size are those RPF1s? also the requiem for a dream music in that video was a nice touch.

im waiting on my friend to sell me his pair

[FantasticVoyages]

Im a Physicist, and in the hospital I work Sportmaxes have been proven to save lives.

I'm hoping I can snag them next week.

17x9.5+18, 17x10+18, 10mm spacers & 235/40/17 tires all around.

wtf does me not driving out there have anything to do with how shitty the place is?
you seriously took my comment toooo personally.
relax !

Lets drop 2k on a motor. Another 2K to build it. Now we're at 4k, with a stock turbo setup still. And still have a shitty block. Why don't you get a motor that won't have to be built to handle your power goals in the first place? Seems pretty logical to me... Oh. And of course you know, the rb/1j/lsx all have gobs more torque than a sr. Or even ka-t.

I'll take an RB over a 1J in my case. Parts for RBs out here are easy to find compared to 1JZs. Plus I've seen enough RB25s out here make 600whp, stock bottom end with just a HG, cams, injectors, manifold with a Holset turbos and PFC.

Its a ninja pole...Mike round it a couple months ago.
