Light Weight Parts & Savings: Minimizing The Heft on Your Turbo Regal

Drag racers (& savy street racers) know a lot of the tricks that can be done to get some of the heft off of these heavy G-body Regals.

Less vehicle weight = the faster your car goes, simple as that.

Someone sent me this list a long time ago, and I don’t know who made it or where it came from, but an awesome job & big thanks goes out to them!

Just check out how all of these small changes can add up to a big weight loss on your Buick Regal!
