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!
(this list is a bit dated, and some newer similar parts may be even lighter, or perhaps a bit heavier, but this list gives you an idea of the parts that can be swapped out to gain an advantage on taking the weight off your Turbo Buick)
