Carbon seats, magnesium roof and bonnet, cf fenders and engine lid. I'm sure all these contribute to the weight savings. And of course, weight of the wing.

 

Hi guys....i am struggling when it comes to choosing seat: The full bucket look amazing and 20kg lighter and I have heard they are comfy...yet I have a bad back! Does anyone have the experience on which to choose? Many Thanks.

 

I have to get the full bucket, i would regret it but this is a 4th car so, its not about comfort, plus they sit lower and i am 6'4 picking the color is going to kill me but i cant place an order till sept due to manual. i thought crayon, but now, no. Its gt silver or guards red at the moment. Maybe gt silver and wrap it later. mexico blue if i could get a PTS

 

I would be careful with those weight numbers. The requirements how to measure them are very chaotic, and although it says "unladen DIN" it might still have some differences. Keep in mind all these cars have 2 fuel tank choices and different weight have different fuel fill requirements, expressed as a percentage of max.

I don't think the gt3's wing matters since the 911R carries the mechanism to deploy the usual 911 wing.

I think the major reason why the 991.2 GT3 is listed as heavier is that some equipment that could be deleted on earlier performance cars is now forced on the customer, plus assorted gear for crash safety, possibly up to some structural changes that were required when the .2 gt3 was certified but not when the 911r came along.

If you have a bad back and intend to take this on trips long enough where that would be an issue, then get the 18 ways. Much more adjustability and comfort. If you plan to track the car more than once in a blue moon and that will be its focus then get the fixed LWB's. They look great, save weight, etc. You can't have it all, choose what is most important to you.

 

Most of the weight difference is just between things are are optional on the GT3 but standard on the 911R.

On the 911R, PCCBs are standard saving 40lbs and the LWB are standard saving 21 lbs, for a total of 61lbs.

So if you simply choose both those options when ordering a manual .2 GT3, you'll get a car that weighs just 29lbs more than the 911R. So 29lb less weight is the only real weight advantage of the 911 is due to the magnesium roof and CF front fenders, engine lid.

Personally I'd rather have a manual .2 GT3 with a motorsport engine and a lot more downforce, both of which more than make up for the extra 29lbs

I wouldn't buy a 911R over a GT3 if the MSRP/market costs were the same or even if the R was 30% cheaper.

 

+1
May not even be 29lbs if radio and A/C deletes are considered 'standard' in the R while unavailable for the GT3.

 

Makes me feel better about missing out on the R

 

Good point. Hopefully, a 911R owner can chime in here, but I thought I remembering that the radio delete was standard on the R, but could be added back in at no cost.

If radio delete was standard and included in the 911R weight, then the .2 manual GT3 in europe with the radio delete option (since backup camera are now mandated in US), might only weigh 10-15lbs more than the 911R!

 

Lightweight Flywheel probably included in R weight too...

 

Why not have both? For the occasion when you don't require the extra downforce, such as a short run to the supermarket?

 

A supermarket run makes no downforce for the gt3 either.

 

If you have the garage space and the cash to buy both, then sure just get them both.

Don't want to offend you as a 911R owner, but my point with the previous posts is that the 911R is only very slightly lighter than a .2 GT3 choosen with similar options, PCCBs, LWBs, etc and overall the 911R does not appeal to me over a 991.2 GT3 with manual, so if you have to pick just one, the .2 GT3 is the clear winner for me.

 

No offense taken. We wouldn't love Porsche as a company if they didn't forever push the technology further with each iteration of car. These are exciting times.
