Any 6speeders have a LSD installed and what kind? Driving Impressions too please.

 

Have a Gen1 2008 CS with a Quaife TBD, the car is about as close to perfect as it can get, the car rotates much better.

Used to own a bone stock 2006 Boxster S while also owning the CS and driven back to back you could really tell immediately the positive effects of the TBD.

Guard makes both a TBD and clutch based LSD for the Gen1 Cayman S. Quaife makes a TBD for the Gen1 Cayman S.

Well worth the $$ IMHO.

 

Hi 2slow,
thanks for the info sounds like it really makes the car rock!

 

Let me know if I can help answer any technical questions for you. I will also mention that even though I haven't managed to get a posting up yet, 6speedonline members get a 5% discount off of retail pricing on all of our products when they are purchased directly from us.

Kind Regards,

Matt

 

Thanks for the kind gesture of 5%! I was thinking 15% discount would be more appealing. Yes any technical info would be great along with some pictures would be helpful.

 

Guard makes the ones that we sell. The best for the Cayman(we trick em up a bit) but out of the box they are still great!

 

Hi Casey thanks how do you trick em up? BTW i love your turbo kit for the Cayman!

 

Well I want a 934, but I don't think I'm getting anytime soon. But in all seriousness, that's just the standing discount all the time on anything for members. You'll have to watch the classifieds for special offerings and group buys that will carry deeper discounts. They're coming. It's just not going to be everything we make

ps. That discount only applies to GT made products. Porsche OEM parts that we resell like bearings, synchros, slider and hub assemblies, etc are not included in that 5%. There's not enough margins on things that aren't our own products to offer it on everything we sell.

 

Thank you Matt, i will be looking out for your specials.

 

Guard makes great Diffs. They are adjustable units, that is what makes them awesome. We adjust them to work with our suspension systems. Definitely the one I would recommend.

 

Interesting sounds good! Can you PM your price for the LSD? Whats the labor time on something like that as well?

 

Talk to Guard, we dont get a deal either But it works!

 

RUFone,
The Club 987S LSD runs $2295
The Pro 987S LSD runs $2595
The TBD for 987S runs $1795
That's list. So with the 5% off they are each +/-$100 less than that.

Casey,
You've got a PM.

EDIT: most shops charge about 4 hours labor to install. Depending on the shop rates tend to be $80-125/hour these days. It's all over the board in my experience

 

Excuse my ignorance. Is there a way to get Porsche's new original kit to an old model?

Would love to know how are the custom settings done for various situations and its effect on gears. I drive in heavy traffic during morning commute max about 30kmph and while coming back I take the freeway at late hour to enjoy the car. Please help how can I change the settings etc.

Much appreciated. Great thread for newbies.

 

Hello,

To my knowledge the new LSD that Porsche is offering on the '09+ Caymans is not something that can be backdated to an older car. Though I wouldn't be surprised if they released a product at some point. It's not a unique gearbox. The same basic design is used in several Audis, as well as some VWs and Skodas in Europe.

With respect to setting the differential it's not something that is ****pit controlled. It's mechanical and has to do with how you set up the ramps on initial installation. Even though there are two settings (45/65 and 50/80) 90% of people are going with the 45/65 setting. This includes professional racers who are running these in cars. It's just the right configuration for the mid-engine design of the Caymans.

However, a more "adjustable" product for a street car is the torque biasing differential(TBD). I say "adjustable" in quotes because it does the adjusting itself. They are also known as torque sensing or torsen style differentials. They are not a "true" LSD because they don't have a mechanical limit on the difference in speeds between the two wheels. For a street car this is actually a good thing. It means when you are driving into your neighborhood making a tight right hand turn, or backing out of your garage in the morning it's got no bind. It's also substantially more quiet than the clutch type locking LSDs. Lastly, they are service free. Because an LSD has clutches inside of it, they wear out, just like your regular clutch or your brake pads. It's a friction surface. A TBD is gear driven to transfer the power from one wheel to the other. These gears are just as durable as any other gear in your transaxle and should give you many years of service without special maintance or rebuilding.

Does that help answer your questions? If not, please reply with more inquiries. I'll be watching the thread and am happy to contribute to the knowledge base around here.
