so you mean to tell me i can fit 15's in my car?

lol no idea.. probably though.. you'd have to check for clearances.. but considering the ex has 16's and has the same brakes (right?) i'd think squeezing down 1 inch should work but i dont wanna say definitely

 

[crock89]

yea they dont fit because of our calipers.

weight reduction, i had some friends in my high school days who would only race on an empty tank of gas - meaning when the empty light came on is when they would race.


now this is risky because some cars have fuel pumps in the bottom of their tanks (some have it in line i believe) and if its real hot out (say summer) you run the risk of over heating your fuel pump.


also take big dump before you sit in car, that'll be an easy ~3-5lbs.


Pull power everything, less power = more power, dodge neons srt-4's dont have power windows in the rear, one of the resons is because they say its for weight reduction (i dont know how true this is), but i know less power does mean more power. no ac, no windows, no cruise.

I dont know how practical this is but its just what i'm thinking when people wana do weight reduction.

And what is the reason for the wanted weight reduction?

Crock89, How much weight reduction have you been able to attain? Did you weigh anything for a before and after? It does sound as though you want weight reduction for racing purposes or is it for fuel economy?

Saves on gas and better acceleration/speed. The less the engine has to pull the faster it can pull it.

Assuming power and weight reduction is a direct relation:
Each time you remove 30lbs you gain 1% power.......
You're in a lot of job to gain significant power!!!

I see. Before you go spending money and taking things apart here is a no-cost to you experiment: drive from 0 to 60 with a 150 lb.passenger in the front. See how long it takes you to reach 0 to 60. Then do it again without the passenger. Now you can determine if you should be investing time in reducing weight or increasing the power of the engine.

my friends run in the 1/4 mile( 9 sec 1/4's) and they say for every 10 pounds its 1 hp. im in no rush to do any weight reduction but every little bit helps. and i would agree with the people who say reduce the rotational mass.... say start with the rotating mass first and go from there.

I never said it was a good idea....just stating why crock might want to do it.

Also, were driving a kia forte, not a ferrari, shaving those pounds and being half a second faster is not really worth it when we will still get beat by any real sports car. Just my opinion, no disrespect.

When painting calipers red today I weighed the stock 2012 Koup wheels with tires mounted. At 46.5 lbs per wheel and tire. Mine came with Goodyear Eagle LS2 tires that weigh 21lbs each according to Goodyear. So that makes the stock wheel 26.5 lbs. I am looking at a 17x7 wheel that comes in at 16 lbs saving 5.5lbs per. corner. I was changing to this wheel because I liked it and now it may have a small benefit. Next is to reduce the weight of the hood made like a ships anchor.

The cast stock alloy wheels are heavy, something like 10 kgs each.

Unsprung mass - Wikipedia, the free encyclopedia

It would be a more meaningful weight reduction if we were to change to a set of forged aluminium alloy wheels. Weight savings could be as much as 40%. But they are costly.
