The weight factor

[Blastofo]

I got a few questions on my mind...

How much does a full trd kit weigh, and does anyone know how much it affects 0-60 and 1/4 mile times?

Also, the same with using 17 inch tires w/ rims that weigh the same as the stock gt-s ones...

And last, has anyone removed the back seats? Is it a bitch to do? If it gives significant gains, I wouldnt mind doing it since I never have anyone back there.

thx

Rear seat are easy to take out. I will be building a custom deck to replace the lower seat and make storage compartments. There is also more road noise.
