Will The Weight Of Wheels Make A Difference On 375 Rwkw?

[Phatboy]

My understanding may be incorrect, but I would think the HIGHER your HP, the MORE difference lighter wheels will make.

To take your example, if a 40fwkw civic changes to rims half the weight, then the drivetrain loss associated with driving those wheels is halved as a percentage (obviously the flywheel, transmission aspect hasn't changed). They may then appear to "gain" a few fwkw.

In your car, halving the weight of the rims will again halve, as a percentage, the drivetrain loss associated with turning the wheels, but as you have 10X more power than the civic, the effect will be magnified in terms of power-to-the-ground "kw gained".

Not to mention that lighter wheels are:

- easier to acc/decel/stop

- easier to steer

- provide better contact with the ground (read the above thread)

- give you kudos!

But then again, you have spent 40k to make a 375rwkw car - more than many GTRs (and probably ended up being similar price). Why exactly do you need more? Do you spend a lot of time on the track? If it's the street, then you won't notice much difference, as you will very quickly overspeed without any effort no matter what wheels you hve.

What do you mean by "you will very quickly overspeed without any effort no matter what wheels you hve"?

Yes it's JUST for the street and maybe an occasionall straight line quater mile.

I just performed a simple test today, I went to the gym, placed a 15 KG weight on the bar, and a 10kg weight on the other side of the bar. I spun both with my hand, and I can honestly say their was not much difference, and bear in mind, this was with my hand, not with a 375 rwkw engine spinning the wheels....

16kg per rim? Sweet jesus.

My 4 rims (18x8.5, 18x9.5) would come in around 30-35kg without tires..

[Turbz RB-25]

I just asked nengun, they told me their nismo LT GT4s weigh 11 kg rear and 10 on the front.

Is it worth paying an extra $2,500 for a wheels that are 4-5 kg lighter AND without tyres? Have a think about it.

[dezz]

10-11kg sounds wrong to me....

As for the tyre comment, all wheels are useless without tyres anyway, so the end result will still be Xkg heavier if the same tyres are used on both sets of rims..

[-Stokesy-]

In all honesty, on acceleration you wont notice a huge difference as you have that much power driving them. Where you will notice the difference is in steering response, ride quality and braking performance (were all that power counts for nothing).

Also if you want traction i think the tyres are going to cost more then the rims

$2500 more expensive? Pffffft. Shop around and you'll find some quality Jap wheels at a good price, there's some 2nd wheels in perfect condition if you look. I got a set of 17x9.5 +12 Volk TE37 with 4 Dunlop semi slick tyres for $3000 recently, all in awesome condition! I think they weigh around 7.5 kg a wheel

I would much rather pay a bit extra for some quality, STRONG wheels that actually come in decent offsets, unlike those Starcorp wheels that only come in ghey offsets and would probably buckle if hit a decent sized pot hole...

[DCIEVE]

Your 16-17kg wheels without tyres weigh almost as much as 32gtr wheels with tyres! Try to remember with bigger wheels the increase in weight hits you harder, inertia is a function of the distance squared.. I can certainly tell the difference when I switch between my 16" 32gtr and 18" ssr professors and thats with over 400rwkw.

You should be able to pickup some decent jap wheels for around 2k - and if you sell your stock wheels that'l get you the extra 500 you need.

"ghey" offsets? These wheels were designed to be used on the R33 GTS vehicles....

[br3ndan]

lol.. 16kg?!?!

Mine are 6.75kg from memory....

If your car is a performance car then get performance rims.

Simple.

try this: put 15 on one side, 5 on the other, get both spinning real good, then try to STOP them spinning. come back and tell us which i harder to stop.

with your power, getting them going wont be a problem. but like someone said before, braking doesnt take killawasps

[Beer Baron]

the starcorps are awesome. buy those. you won't notice it.

*this is what you want to hear. so far everyone has advised you not to buy them, but deep down you know you want to. just ignore the other posts and buy them.

Everyone....? Go back and read the thread again.

Anyway, it's too late, I just purchased the Lenso D1R Hyper Silver wheels in 18x8.5 +35 and 18x9 +32 deep dish for my R33 GTS-T.

I had the shop measure them up on a scale, and they turned out to be between 11 - 12 KG.

Considering nengun informed me their Nismo LM-GT4 wheels weigh in at 9 and 10kg respectively, I thought this was pretty damn good!!!

Thread can be closed now, thanks for all your opinions fellas, you kept me away from the nasty heavy star corps, 16 kgs is alot......

Cheerio

[joeyjoejoejuniorshabadoo]

if you are getting the D1R's get better offsets....

18X9+15

18x10+22

would fit with a lil bit of work

[Turbz RB-25]

Are u kiddin? 18 x 10 +22? That'll stick out worse than my dog's balls when he hasn't shagged for like 2 weeks.

My car is lowered, I still want to keep the tyre under the guard while having reasonable camber.......

[Turbz RB-25]

Can someone PLEASE attach some pics of 265/35/18 tyre on an 18x9 rim, I wanna see if there is alot of tyre buldge.....

If their is, I might just go 255...

Cheerio fellas

Yes, i did indeed say ghey offsets. Anything over 30+ is a joke really if you want it to look good without using spacers.

...and this is the reason that majority of Aussie modified cars fail hard. You could easily fit these rims under the car with minimal guard work and -1 deg negative camber.

[Piggaz]

275/35/18's on 18X9 inch

Excuse the size.

[TALBO]

Huh?

You're a clueless gitt...... I belielive looking good is down to personal opinion, some people like having +40 offset, others like having +15..

As I said before, those starcorp impuls were DESIGNED to fit the r33 GST vehicles, so no, they are not "ghey" offsets, they are what it should be.

I'd like to see you fit 18x10 +22 on the rear of an r33 (thats lowered) with "minimal" guard work and -1 neg camber... Someone one here PLEASE prove me wrong...

Actually, yeah they would fit....... if your car isn't lowered beyond the point where the wheel goes under the guard...
