Weight Reduction (Gen1 & Gen2)

Thanks to John GTR from rdtiburon.com for this DIY.

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.
