Brings em out of the woodwork like roaches clamboring for cover when ya turn the lights on.

I'll relay to a link where it was talked about before some other, more dissentive people got on-board with insults and name-calling and caused the discussion to be conducted, and later concluded off-forum. And that situation still exists today. We simply cannot hold these kinds of discussions openly at a public forum on anything we might like to develop for ourselves or bring to market. A good analogy would be a camel being nothing more than a thoroughbred race horse designed by a forum or committee. It just doesn't work! "You can please some of the people some of the time... "

The one thing I will say up-front and openly is that the SOP differences between lightweight/motorsports and stock CV's are WHOPPING HUGE!!! Each subsequent set of lightweight CV's added exponentially enhances the previous pair. The more LWMS CV's you add the exponentially better the chassis responds. This is not a subtle, slight or barely peceptable modification. It's like driving another, far far lighter car!! The car accelerates and pulls away from corners HARD! But it is an expensive mod when using new CV's as they are expensive to begin with and lightening, lapping, honing, using higher grade (Grade 10) ***** and custom cages more than doubles their average street prices and I only use GKN/Lobro Glaenzer-Spicer "real deal" Audi CV's for conversion or rebuilding. And there's 8 of these on my car with inboard/outboard rear axles, inboard front axles and front/rear driveshaft. But I'm now machined &amp; tooled up to do "rebuilt" CV's and offer them on an exchange basis. This keeps costs down to right at "$100 per." But the friend that does the grinding for me on these is buried up to his eyeballs in a Hewlett Packard contract grinding printer/scanner guide rods for HP so here I sit amidst 200+ pair of new/used CV inventory ready to be lightened and no one to grind the weight off the outer housings for me. I tried doing them in the lathe but it's slow-going requiring over an hour each. Fine for doing my own but not for doing hundreds &amp; hundreds. Grinding should take less than 5 minutes each! Very frustrating!

But these have been in use for 2 years this month on my car and the Champagne AAN/A4 did win Pikes Peak Open Class Hillclimb in 2005 and every other hill climb it entered that year using these so there's at least an element of "bullet-proofness" associated with them. One in pic utilizes gun-drilled and head milled titanium fasteners for additional strength/weight-savings. Don't even ask ;-)<ul><li><a href="https://forums.audiworld.com/9080/msgs/327770.phtml">Lightweight Motorsport CV's &amp; Driveshaft</a></li></ul>

that it takes less energy to turn a lighter object. Heck, even my 6 y.o. daughter knows that from going to the science center. ;-)

Yeah John, but in all fairness your daughter does have 4 years on those guys! ;-)

You're and idiot borat, that all I have to say. These gentlemen have explained the rest. I personaly am glad somebody is working to make improvements on this engine.
