Mk1 vs Mk2

Balancing weight fore and aft, I presume. Plus there is no space in the rear of the car for a battery. Plus Porsche loves tradition: my 1972 911 had a pair of battery boxes way out in the front quarters.

. Kind of crazy to have useless weight, but I guess it was necessary to tame the handling. Supposedly Porsche did that after a bad review of handling for the early 911 by Road & Track, though I have not verified that story.

Does anybody know the weight difference between identical configurations of mk1 vs mk2 ( e.g. 2wd 6-speed coupe mk1 vs 2wd 6-speed coupe mk2)? I've never seen that stat published. I would think the Mk2 is slightly heavier, but I would guess that the difference is probably pretty small .

There is a ton of great information about each generation (including year by year changes) in Adrian Streather’s 996 The Essential Companion book.

- "The 2002 six-speed coupe weighs 2,959 pounds compared to 2,910 for the 2001 Carrera coupe, which is an increase of 49 pounds"
- the cab gains 60
- the Carrera 4 gains 59 pounds
- C4 Cab is 70 pounds more.

Here’s a place to check weights: https://www.excellence-mag.com/resou...3#.W2Ge1BZOmaM
The Excellence Magazine article summarized above says exactly that (on page 64):
- "The 2002 six-speed coupe weighs 2,959 pounds compared to 2,910 for the 2001 Carrera coupe, which is an increase of 49 pounds"
- the cab gains 60
- the Carrera 4 gains 59 pounds
- C4 Cab is 70 pounds more.
I think the Mk1 is 2901 rather than 2910. So, if my math is correct, with 20 additional HP, the Mk2 only has to move 9.24 lb per hp (2959/320) versus 9.67 lbs per hp (2901/300) for the Mk1.

Thanks! Amazing data per model per year -- never knew this existed (now bookmarked in my browser)
Excellent!! (no pun intended)

I really wish Porsche would have continued the old super-light alloy wheel studs on the 996 -- would have been just enough to drop it (barely) into the 2800's (from 2901)

It's ironic you said that. I have had my 99 in the shop getting nearly all of the suspension replaced. My car had studs with aluminum lug nuts. The shop recommend I swap those out, which I did. They are super light, but the treads are easily damaged.

Speaking of light, last night out of curiosity I weighed my wheels with a bathroom scale.
The stock wheels on a '99 996 (option 408, technology turbo twist hollow spoke): Rear 50lbs, Front 43lbs.
This is with 265-35-18 in the rear, 225-40-18 in the front, Falken rt615k+ with about 2K miles. The front wheel is 7.5x18, the rear is 10x18, my estimate is that the rear wheels are 24lbs each, the fronts 19lbs each.

It's somewhat amazing to hear this. Never heard of the factory using those alloy lug bolts on the 996. Would love to see a picture of them if you still have them. If they are anything like the old lug bolts, it's absolutely crazy how light they are compared to steel or even titanium.

Partially correct...the bean counters had already gotten to the car and cut a lot of corners on parts, but the early production appears to have been done on established production lines alongside the last of the previous air cooled cars by skilled craftsmen...not by robots...as the new lines were not up and running yet. That's one of the reasons Jake likes 'em....still craftsman built.
I know Jake and other would have some stories about D chunk and other issues with the 99 model years - there are 25 modes of failure on this engine - but it still seems pretty reliable compared to all other 996s.
And yet, they have the lowest price. And coming up on 20 years old too, which could make them a classic.
BTW, an aside, Hagarty won’t insurance a classic unless I get a 3rd car.
