New Yaris !

[Yarisagos]

Hey guys,

Just got my Yaris, its a meteorite metallic. I wanted the blazing blue, but the sales manger went nuts on me and told me take this car home now for -200 invoice or wait 6 weeks for the blue and for more money, they won! I hate those guys, lol.

I done my home work, well i hope so. Please check my data for any errors and better ideas.

My stock wheels are 15" steel, tires-P185/60r15 84T, Bridge Stone.
I am guessing wheels weight at 16 lbs and tires 17 lbs.

My new rims are Sportmax 001 weight in at 20.5 lbs.

New tires are Falken Ziex Ze 512, 205/40R17 weight in at 17.6 lbs.

Stock weight is 33 lbs total.
New setup comes in at 38.1 lbs total.

Does the 5.1 Lbs make a big difference ?
I try going to 16" wheels but it only lower it by 3 lbs.
Also i will be installing NF210 springs.
Anyone see anything wrong with my setup?
Thank you guys, your insight is greatly appreciated.
