Great write up, but I assume you only plan to run your cup in club races?
I believe since you have used non PMNA parts your cup is no longer legal in IMSA or Pirelli Trophy Cup West.
I truly believe you have built a better box and I feel bad for Guard as their gear sets have been disallowed from a couple of sanctioning bodies.

Don't feel bad for me, though I do appreciate the sentiment. I've got plenty of gears in PCA,POC, NASA, Grand Am, World Challenge and other series around the world.
PMNA threw their weight around in IMSA claiming they couldn't have an "inferior" product damaging ther marque with DNFs. We all know it's because I was cutting into their profit margins. But IMSA isn't the only swimming pool around.

"When I decided to get a GT3 Cup car the biggest mystery to me was the sequential gearbox. What do I know about it? Almost nothing......"
Mikymu, I was glad you bought a cup because I knew great threads like this were coming. Thanks!

Hey Mike!
Thank you for sharing this! Our 2008 is going to have the engine (currently ~70h) and the box (~40h, 2009 spec) rebuilt and updated to latest spec @ Porsche Motorsport in Weissach next winter.
The parts still feel nice and sound good and healthy but we want to have maximum security and lower cost then repairing a broken trans or engine...
Loose-fit is already much better then '06 & '07 but 2012 gears are the way to go if you want to get the sealing on the engine to keep the car legal for the Sports Cup or GT3 Cup-Challenge here in Germany. That's why we can't go for aftermarket-parts like Guard or others even if we'd like to...

Thanks Matt, I did not realize you gave me the fastest gearset from your shelf
I knew the rebuild gearbox will be better but I was not prepared for an easy 3 seconds shot in the arm![thumbup](https://rennlist.com/forums/graemlins/thumbup.gif)
I guess one of your GT LSD will be in my wish list next. What kind of LSD ratio does Cup car use?

Thing is that there is almost no other supplier for Cup-parts than Porsche itself over here.
If you decide to sell the car here everyone wants to see the Porsche-sealings on the tranny and the engine.

Maybe karlleonard can also tell you some stories as he sells this things here very often...

Spent my morning in a meeting with some very nice German gentlemen and have to get after it with respect to today's orders and customer inquiries so I don't have time to hang out and chat. However, I promise to come back and comment both about your 3 seconds a lap and the LSD. Probably be some time over the weekend...
I hope so! ![Smilie](https://rennlist.com/forums/images/smilies/smile.gif)

My parts are available in Germany. I sell to a number of people over there. And shortly one will even be able to purchase them trackside at The Ring.
