Weight Reduction

Thread Starter
The stock Tiburon weighs about 2633lbs.
Reducing weight contributes to lower 60' times and less strain on the drivetrain. To reduce weight in your Tiburon, you can follow these steps. They are only suggestions and some are NOT legal on public roads and may NOT be safe. Use your own judgment when following these steps. Some are only for the weekend/track car. They are not in any particular order.

Some thing to buy, too expensive for me, but titanium bolts, I think some people with evos lost about 20 lbs or something, also if you can make a titanium IM, or cf but I tink titanum is lighter because some people replace theirs on the 340r or some kind of lotus I remembered

Most of these mods don't interupt the luxury of the daily driver.
I like to drive "fast with class", so I didn't do things like remove the seats and carpet.
But there are a couple things in there that most people would forget about or never knew before.

Another thing you can add... the Tib's wiring harness is covered in foam up under the dash to keep noise down.. you can spend several evil days removing it.
Personally, all those ideas are great for a full on race car.. but not too practical for a daily driver.

are aftermarket radiators lighter than OEM's? I would like to buy a bigger radiator but would also like to keep the weight down as suggested...
<div class='quotetop'>QUOTE (JonGTR)</div><div class='quotemain'>Lighter radiator</div>
Do you mean smaller, or aftermarket?

I thought I had added that already, but after looking at it for a while, I knew I was forgetting some things. I also forgot the firewall padding. It's just there for road noise, which I heard isn't much worse than stock.
<u>Mods:</u> Can you add "ECU covering" and "Firewall insulation"?
