I would have recommended the 764 pressure plate and the Genuine 964 RS flywheel vs the aluminum with metal friction ring.
The aluminum flywheel creates issue for higher than STOCK power levels on the track.

Since we are still waiting on other parts of the build to come together, I’m going to post about the power upgrades. This car is fast and powerful out of the box!
To get some perspective, here are the Porsche 996 turbo specs for a stock car:
these cars are are really light but make only 180-190 hp at the wheels. I’ve seen some really well driven cars haul the mail! Also, they are about $30-40,000 fully built and ready to go.
Spec carrera era is also a really cool class and here are a few stats on these guys:
I badly want this. But honestly I would just be a moving chicane out there lol.
But, and this is a big but (ala J Lo), Porsche gave us the Mezger engine with turbo chargers!! After being on this site for 16 years, I have seen more builds than I can remember that have refuted in crazy horsepower! To all the tuners out there, I have to say, what you guys have come up with is truly amazing.
so to level the playing field a bit and compensate with my “heavy” car....MODS are in order.
‘After asking a ton of questions, I decided to go with K16/24 hybrid turbos. For those who have read my thread on that, I will spare you the torture of going through that all over again. For those who are gluttons for punishment, here’s the link:
if you want your car to be fast and yes even nimble weight loss is the key. its not very hard to drop about 300 odd lbs off the car. from there it gets tougher but can be done
rear wiper
foam padding off the carpet
stock seats traded for race seats
lighter battery
remove all parts out of the frunk
lighter stronger wheels
main cross brace under the motor
window the front and rear crash braces
rear seat removal
these are the basics. if you want to go even further consider removing all the sunroof parts and install a non sunroof roof panel. theres a weight loss thread at the top of the forum

Hey 32krazy!
I think ink this is a great point and this is what we are going to do:
rear wiper — stays for now foam padding off the carpet — stays for now stock seats traded for race seats — recaro front seats being installed lighter battery — have interstate in it for now remove all parts out of the trunk — done lighter stronger wheels — OZ allegerita wheels main cross brace under the motor — stays for now window the front and rear crash braces — stays for now rear seat removal — these are gone to make room for the rollcage
i definitely think these will make a difference. I have read a lot about weight loss and it basically is free horsepower and reduces the work the brakes have to stop and cooking brakes is an experience I would like not to repeat!
I found a pretty interesting thread thread about weight loss for our cars and there is just a lot of information on it:
I’m curious to know what my car weighs and I will be putting it on the scale at my next opportunity. That said, the driver can lose a few pounds as well so I’ll be working on that as well.
yeah buddy! This car is heading up to the track this weekend fingers crossed! I literally bought it and left it at the shop so I am very excited to see what it can do!

Well....the weekend came and we still needed some more time. As a few have chimed in about the fitment of the 380mm calipers in front, i was able to go check out things a couple of days ago and I got things confused. The plan has always been to put 997 gt3 brakes in the car. In my case they are the 997.1 brakes and are 350 mm in size. The 997.2 gt3 and gt3rs have the 380 mm front rotors.
So comparing what a stock 996TT has to a gt3 997.1 the sizes are 330mm vs 350 mm. Also, the 996 TT has 4-pod front calipers whereas the gt3 has a 6-pod front caliper. I have read some very interesting threads on this site from some very knowledgeable folks about stopping power and heat dissipation as well as what happens when you change the brake bias. A lot of the stuff goes over my head.
However, for those interested in more details or thinking about changing things I have included a link:
Front disc Front pads Front pads Rear disc Rear pads Rear pads Brake pad front part number
A couple of observations:
1. The rotors are heavy!
2. They are unidirectional
3. They are pretty thick
4. The pads are yellow
5. The pads are very course and when I ran my finger across them, I got the sense of how grippy these things would get when they are hot and hit hard.
As a foot note, I could have gone with 380 mm front calipers and gained even more braking power. In the post I attached, there are some pretty poignant comments about how to do this.
However, if I do that, I would need some hardware adjustments and new wheels because the wheels that I have for this car just don’t have the clearance. The 997.2 gt3rs has 19” wheels and that makes it a lot easier to fit all this good stuff in to the wheel. I am hoping that I will like this setup a lot and I’m looking forward to seeing how well the car stops. So far, in my limited experience, I haven’t found a car yet that I wouldn’t like just a little more brake!
check out giro discs, it will save you some unsprung weight, I have RS29 yellows up front, and the P90 yellows in the rear and it's been a good combo, I have a set of black padgid pads thinking of using these in combos for the rears for slightly more added rear bias
i did have a great time this weekend! Even though I did not get my car done in time for the event, I was able to bring my other car. I dropped 5 seconds off my previous pb and had a blast! Great friends, great community, great competition, and great expert teaching! Look beautiful, but man, it was Hot!!! Mansell 3.4 mile course
p.s. In the background, in the pit, you can spot a GT3R. Those things are scary fast and more like low flying aircraft. Amazing cars!!
