What kind of affect would say a 11 pound wheel have on my 94 GSR, as far as handling, acceleration, braking, 1/4, etc.. I know they would all improve.

But how significantly. What's your best guess and how a 60', or 1/4 time would change.. stuff like that.

 

Probably, nott much.

 

It also depends on the diameter of the wheel. If it's a 15" 11lb wheel versus a 17" 11lb wheel. I dunno if there is a 17" lb wheel, but I'm just giving an example.

The moment of inertia (I believe that's the term) is increased. It takes longer for it to get up to speed if it's a larger wheel.

All in all, if it's a smaller/lighter wheel, your launches and initial 100ft or so of the drag will be improved. At higher speeds, it doesn't do too much.

 

The term moment of inertia is correct.. strictly speaking, it doesn't necessarily take 'longer' to get up to speed, but rather more energy..

But, yeah, I understand what you're saying.

 

There you go, that's what I was trying to say.

 

yea man. for instance, I have an ITR wheel on my GSR. I can decelerate faster, engine brake more efficiently, engagement is a bit more chattery.. which isnt too bad I like to feel a clutch. The ACT HD/SS is nice on it. The diameter is the same in keeping with the current convo, on 5lbs of less rotational mass I have noticed a nice improvement over stock in transient response as well as engine braking.

 

u feeel that much of a difference with only one wheel on ur car?!?!!

 

oh yea.. sorry for the double post... but ummm only 1 hub of ur car is a 4 lug conversion

 

why dont you pass what yer smokin bud! I aint braggin, I am just illustrating a point of something that worked for me.

my $.02

what information besides knockin do you have to share?

Depending on the your suspension spring rates lighter wheels offer better ride quality and handlig since they don't load the springs as much when you hit bumps.

I had the ligher 94-95 GSR wheels and switched the slightly heavier 96 GSR wheels and it was like night and day(got worse) even though I could not detect a weight difference by hand.

 

BIG difference in handling going from 21 pound 17s to 11 pound 16s for me...
The car responded to road conditions much faster, allowing the rest of my suspension to do what it was made for - such as driving over bumps/potholes in the road. The prior wheels would bounce along sluggishly and make the car jerk, but the light wheels would react quickly, allowing the shocks to absorb most of the bump.
A pretty big difference in acceleration for me. Not sure if the difference would actually show up on paper, but it might be good for .1 to .2 in the 1/4 mile if you are coming from extremely chunky wheels.

Tires are really going to make the biggest difference in what you asked. But I say, pair up some excellent tires to some lightweight wheels, and you have an awesome setup.

 

somewhere in there people failed to realize when I said "the ITR wheel" we were/are talking about flywheels. in my post I eluded to the wheel having an ACT HD/SS clutch kit on it. if I wasnt COMPLETELY clear and steered this thread off course, I apologise. I can imagine having lighter wheels and the lighter flywheel... wow now that would be superb.

 

I dont know if you know this, but if you check vtec.net in the integra section it lists the weights of the GSR wheels:

94-95: 16lbs
96: 15.5lbs

there is a wheel weight table, check it out:

Just wondering, but you do you have one wheel with a five lug conversion?

 

That's weird. Maybe that's why I could tell the difference by hand.

 

no, I have a GSR to ITR flywheel conversion. why would I mention my clutch.

some people.



have a few of these,



and a couple more of these while you are at it.

 

Not too much improvement for straightline performance, but you will definitely feel a noticeable difference in braking and handling.

 

sorry doo... i stand corrected....

i saw the second post sayin 15" and 17 " so i assumed the original post was about wheelS.... and yes i have an ITR flywheel in my trans.. couldnt feel much of a difference... felt 10 times more of a difference with my 4.785


sorry bro

 

hey man,

hows that 4.785 on the highway in 5th? Whats your cruising RPM/speed?
normally I am looking to shift again in my GSR at 4K at 80mph... that
final drive may accelerate well, but damn... I'd want a lower 5th gear ring
or a 6th gear! did you compensate for this>?

Mike

 

fifth on the freeway is koo.. its mainly the other gears that i have grown to love now 4th feels like 3rd 3rd feels like 2nd and 2nd feels like 1st aslong as the RPM's are above 2500 in any of those gears it rips and i can definetly see why you should not have a JDM final drive with boost cause 1st gear on my car gets me out of the hole with a quickness


freeway cruising is at 4500 at 80 mph..... and if u can believe my gas mileage has gone up because of the fact that driving around town im most of the time in 4th gear cruising at about 3-4 grand at around 40-50 mph.... ive also noticed an influx in my speeding tickets though


oh yea... on the original post whether it was for flywheel or wheels i have the Racing Hart CP-035's and i can tell a major difference in all areas, braking acceleration and looks
