Why not 2900? Or 3100?

Is it just some nice round number?

There has to be a balance between HP/Weight ratio and total weight of the car, otherwise you're just shedding pounds to meet some made-up line of demarcation of what's lightweight and what's not lightweight.
^^

...further to this, what is goal of the weight savings? Lap times? bragging rights? steering feel?

I don’t know, but my 997.2 GT3 was 2950 lbs with 1/3 of a tank (bucket seats, PCCB, full race exhaust, stock battery, no lift). It put down 432 whp with the Akrapovic race system, custom tune, and ran on E85. Aside from the performance gains and improved handling associated with sub 3000 lbs, perhaps the main reason someone us still chase it is because the newer cars have gotten heavier, and we’re just fighting it and trying to keep them lean like before...

Its just passion. Not everyone will get it and not easy to explain. It’s like asking “why replace exhaust, wheels, etc?”...

Some of us just do.

Isnít it a little incongruent to question the point of dropping 100+ lbs. while we all complain when new cars add that much weight?

My .2 GT3 tipped the scales at 3205 with just over half a tank (extended range) and no driver. Lightweight battery will be going in later this month so should be under 3200 after that. Not sure where else to remove weight with harness bar, exhaust, and track wheels already on board.

PDK and carbon buckets are the only options that really would have any impact on the car's weight.

For the most part, the only weight loss you will be able to really "feel" is off your own body.

I get that losing a little weight here and there is not a rational thing in terms of cost justification. But clearly Porsche sees fit to replace the magnesium roof with carbon on weissach cars to save a measly few pounds (albeit rather high up) so it's all in the same spirit!

While this is motorcycle-related, it's also weight-related.. and specifically unsprung weight. Check out these motogp calipers.. I'm putting them on a bike build I'm doing.. about half of the weight of a traditional monoblock.. even drilled out pistons.. this is where all the weight saving funds should go for your project, reducing wheel, rotor and caliper weight if possible-all unsrpung weight which is worth 4x any other reduction.

If you think car guys are bad, go spend some time on a road biking forum. People are looking to shed grams!

I may have the lightest large aluminum frame specialized diverge on the planet. Besides the frame everything is titanium, carbon, magnesium and ceramic. That was my 2017 hobby. Itís collecting dust now. I wanna say it weighed 17.1lbs. For a large aluminum frame thats pretty much as low as you can go.
