THE LIGHTWEIGHT PARTS THREAD by Kingofimports.com

**KingofImports.com** · 07-02-2004, 11:44 PM

Goal: To create a comprehensive thread listing the weight of various parts, both stock and aftermarket, for the STi. This should save us some of the headaches in finding answers to the common questions related to how much a performance will save in weight or how much weight one can save by removing a stock part.

This of this effort takes a significant amount of my time. Please be patient as this is a work in progress. Keep in mind that I have a business to run and bills to pay. This will get updated over the course of a few weeks. I will try very hard to get a significant amount of work done in the next few months.
