I've got GT3 RS due YE. Went for black but with the standard silver wheels - orange wheels would have subjected me excessive **** taking. Plus look better with yellow ceramic brakes.

My concern was whether Press would slate RS versus GT3 in view of price differential. So far, RS getting rave reviews.

But is this in part because RS has different sports exhaust. All RS reviews comment on exhaust valve that opens at 4K rpm and can be over ridden with Sports button. Seen no reference to this re GT3 reviews?

Also I read somewhere that RS has different roll cage with more bracing?

Shame about the limited (and rather naff) colour range. Was hoping they might offer Gulf Blue if orange decals. Also the silver with option of black decals etc would have attracted a lot of punters.

Did anyone else read the very short comparo of the GT-3, GT-3 RS, and Cup? It seems the author wasn't too impressed with the differences between the GT-3 and the RS. And that was with the Euro version. There seemed to be only around a 40lbs difference between the two. He stated the price should be $123K for the RS.

Does anyone know if the suspension is calibrated differently in the RS? Based on the press it appears that it might.

So the differences that I can remember for US cars:

color and graphics
widebody
wider track due to wheel offset
yellow stripe on steering wheel
front hood is cf IIRC
split rear wishbones for more adjustability
rear wing
NO HOLE

it's 100% certain that we aren't getting the flywheel and lexan?

Isn't the RS-specific non-sunroof cage a bolt-in affair that takes place at the dealer?

edited to add fly, i thought we are getting this.

pretty sure lexan is killed for the us; there were detailed posts a while back showing PNA DOT waiver application and response.

100% certain
NO
Lexan or CF Seats (NHTSA regs)

Both the 997 GT3 and 997 GT3 RS use the same exhaust.

Press material indicates different calibration for the suspension. I bet the rear springs are different due to the modified geometry, wider body and different weight.

There is some bogus data on the press material. Porsche indicates the RS is lighter than the GT3 (at least this time they don't refer to the GT3 ClubSport). However, the regular ROW GT3 comes with the heavy power seats, contrary to the ROW 996 version. As soon as the RS seats are installed in a regular ROW GT3, the regular car becomes lighter than the RS.

The weight for the ROW GT3 RS in the Auto Motor und Sport Test is 3,141 lbs, with no sunroof, PCCB, CF seats, plastic windows and half cage.

The US RS will save close to 40 lbs on the cage, but it will gain 56 lbs on the seats, another 37 lbs on the steel brakes and 10 lbs more on the glass windows. That's around 3,200 lbs. Add sunroof, dual mass flywheel and aluminum hood, and it gets close to 3,270 lbs for the regular US GT3.

This is the reason for the 415Hp having a difficult time to show against the 380Hp on the old car in acceleration tests. The acceleration numbers were noticeable between the Mk1 and Mk2 with just a 20Hp increase. This time a 35Hp increase is not showing.

Yeah but the 997 GT3 looks and sounds nicer......

responding to NJ, I for one think the big difference b/t the 996 and 997 GT3 variants will be the superior 997 chassis, which uses what pag learned from the 996 gt3 rs, not so much the motors. (though I bet the lighter internals will provide a more rev happy motor). Less bumpsteer and nervousness, and more compliance over bumps for better traction under real world cornering. Also, linear rate rear springs vs. the 996 progressive springs (more predictable), and a revised diff for less understeer at turn-in. Stuff like that.

A 996 GT3 with RS suspension and Moton club sports would be a nice alternative to the 997 GT3 though, and you wouldn't have a hole in your roof.

NJ,

Where are you getting the fact that the GT3RS NA:

1. will NOT have single mass fly wheel
2. will NOT have a PCCB option
3. will NOT have CF boot
4. Will have sunroof

Your argument survives ONLY with a plethora of un-confirmed assumptions.

Re-read his post. I don't think he made any of those statements.

I'm with you on that. The biggest improvement comes on the chassis. Basically, we are getting an improved 996 GT3 RS with more power, a closer ratio transmission (still long geared), better aerodynamics, better brakes, active suspension and some extra weight due to more comfort-oriented accessories.

The rear bump steer in the 996 GT3 is bad, the front bump steer is bad, but not as dangerous as the rear one. Definitely the 997 GT3 will be easier to drive at a fast pace (and safer).

The new front and rear wheel carriers reduce bump steer. They have increased rear track. The uprights are lighter than the ones on the 996. 12" rear wheels help to put more rubber to the ground on turn exit.

In straight line the 996 and 997 might keep a similar pace, but once you start turning, the 997 will do better.

agreed

I was making the weight comparison between the 997 GT3 RS and 997 GT3 at the end (3200 lbs vs 3270 lbs), using the numbers from the ROW 997 GT3 RS.

Under the assumption that the US GT3 RS doesn't get the rollbar, but gets the glass windows, power seats , LWFW, carbon hood, no sunroof, the car will be around 60 lbs heavier than the ROW GT3 RS. With the optional PCCB, it will be just 20 lbs heavier than the ROW GT3 RS. The CF seats will make it lighter .

For the regular US GT3, compared to the US GT3 RS, you need to add 20 lbs on the dual-mass flywheel, around 30 lbs on the power top (my guess), 15 lbs on the aluminum hood, 4 lbs on the rear spoiler, close to 70 lbs heavier than the RS.
