997 GT3/RS Performance Mod Thread******

[WildBill]

OK guys, if everyone is game, we can call this the official 997 GT3/RS Performance Mod Thread. Let's hear what you have done, what works and what don't, and would you do it again. Maybe a consolidated list of successes and failures will make it easier for those of us looking to enhance our cars performance. Approved Forum Vendors/Sponsors are welcome to post their hardware and performance claims but I would really like to hear real world results from those that have taken the plunge. Photo, Videos, graphs, dynos are welcomed and encouraged.

Thanx

Lost 15lbs by choosing the "tall" rather than "grande" Mocha at Starbucks and eliminating most bread from my meals. Not sure how much horsepower I gained with this mod, but it sure makes it easier to get in and out of my car.

i think you'll get the same intake between tall and grande. do tall non-fat. staying away from bread helps. i have trouble getting away from rice though.

Ok, I'll go first:



Carbon Fibre Aero - (CAD designed and Wind Tunnel Optimised) - Autoclaved - the front and rear spoilers are optimised to balance (front aero works a treat!)

Rear Carbon Diffuser (flat floor) - requires rear Cup S conversion.

Carbon roof (now available and fitted (not in this image)).

4Way Suspension System - (tranforms the car) - much more complient than OE system and the front end is now what it shoud be. We found 2.5s at Estoril (Spain) with cup car with this system.

Sequential - (ask Luis who posts on here)

Alloy Race Rads (+ cup grills)

380mm Oakley Design by Brembo brakes (on this car) Also have 400mm carbon ceramics using an 8pot light weight CNC caliper and multipad (Front) and 380mm carbon ceramic with 6pot caliper and multipad (Rear) - currently fitted to Oakley 997 GT2 (awesome is not the word).

Titanium 'Supercup' Exhaust system (removes 25+ kgs) with RSR pipes finish (Cup S rear style conversion available).

Carbon Wheel (you guys know all about these)

Carbon Rear Roll Bar (cage on the way...)

Carbon Seats (2.5 kgs each!)

and more...

Wow!

[sasportas]

Oh yeah, I also did the Intrax suspension from Oakley. Lost weight, gained composure from the car.

[GT3Ranger]

Oakley Design are you sure about those seats. You state seats that weigh 2.5 kg. Wow that's 5.5 lbs. Frankly I find it hard to believe, if not just plain dangerous.
I have Sparco DTM CF seats that weigh 7 kg. each and that's without mounting brackets.
BTW who makes these seats? Correct me if I'm wrong but from what I've seen Oakley Design does not make any of these products/components.

For the price, I think I would get the Hollinger 6 speed sequential transmission that they use in the RSRs.

Oakley's carbon fiber frame looks great, if I did not already have the half cage from the factory.

I have:

-Front grill radiator guards from Sharkwerks
-996 GT3 seats (leather, from 04 GT3)
-Fire entinguisher
-muffler bypass from Sharkwerks

No car wrapped in clear film for me.

- Real 16 pound weight savings (stock muffler weighs 20 pounds total) from the rear of the car
- 18 gauge T304 tungsten inert gas welded stainless steel

(4) Fabspeed

997 GT3/GT3RS Side Muffler Bypass Pipes $1,295

Superb sports car dual tone sound, throaty and deep at idle and medium speeds. It's docile enough for the wife/girlfriend, but strong dramatic sports car sound when you floor it and go up through the gears!

There are other systems, just a few presented here. Thanks in advance!

I know the bolt was down - just wanted to get a quick picture during the install. I can post fully installed pics of the whole set-up if anyone is interested. All I can say is "no" to PASM, and yes to good old fully adjustable set-up. An added bonus is the the four dampers are about 20 lbs lighter than stock.
