Carbon Fiber A Arms
You might enjoy the attached pictures of a carbon fiber a arm for Type 964 and Type 993. The ball joint, by the way, is titanium as are the fasteners.

I mean "artwork" in the same sense as I consider a set of SSI heat exchanges "artwork"..elegant parts. Considering that the factory "A" arms are cast aluminium, I am certain the carbon fiber and the titanium ball loints are a major improvement.

Thank you for the compliment. By the way, have you noticed the titanium/aluminum drop link in the picture (to which will be attached a 4130 adjustable anti roll bar)? And, although you cannot see it, you might be interested in the attached pictures of a one-piece cast titanium upright with a titanium centerlock hub with integrated titanium driving pegs and a 300M center screw for a Type 964 and Type 993 -- the carbon fiber duct on the back attaches to a proper wheel bearing/brake cooling system. Although this is a work in progress, over the next few months, attached to it will be a titanium/aluminum track rod, billet titanium struts with adjustable dampers, two-piece (main and helper) titanium springs and lithium aluminum 8 piston calipers and carbon ceramic rotors mounted to a tianium/aluminum brake bell.

It goes without saying that these are both impressive and beautiful parts. My compliments to the chef.
My question is thus. The original parts, for example the lower control arm, is made of cast aluminim. Why do the new parts which are made of a completely different composite material with entireely different properties duplicate the exact look of the original? Wouldn't it be advantageous to chage the profile to take advantage of the properties of the new materials?

Mr. Linton,
I've read most of your posts, and clearly you are an expert when it comes to the things we have no way of getting at all. You shy away from people who asked you the price and availability and yet you kept posting all these pieces and claimed to have an EFFORT in which your were involved.
If they were technical to this board, I can not see how and why they were since you are not sharing ALL of your informations other than just luring us with your experties.
All talk and no action. So long "carbon kid"

JC:
As to your very good comments, several answers. First, these parts were designed to bolt directly on to existing vehicles and to work with all of the other existing front suspension components. As such, the mounting points could not be changed. Second, they were designed to be strong enough to withstand other than full race conditions. If this were not the case, certain liberties (e.g., pocketing) could have been taken -- and for short races, designs could be different than endurance races -- on the other hand, the forces exerted by different other components and by the aerodynamics of the vehicle, by each particular track, etc. could also affect the design. Third, although the design looks very similar to the original metal piece, the design is different in subtle ways --taking into account the properties of carbon fiber as well as all of the foregoing issues. Finally, if one is starting from a street car based racer (as, e.g., today's GT3RS), rules and resgulations might not permit you to entirely change the suspension design -- although a better design could, particularly for all out racing and being relieved of cost constraints, be achieved.

My understanding is that these pages are informational and people share interesting ideas and solutions. These baords are not a suitable forum to describe the engineering that go into components -- much the same as neither Porsche nor other manufacturers release technical drawings nor calculations. As to availablity and prices, these parts are not now available to the public and, if they become available at some point in the future, the channel(s) of distribution would not, I would think, include Rennlist as it was not set up for this purpose. Finally, should you and others rather I did not post what I thought would be pictures of interest, I will, of course, abide by your wishes. I do not, however, mean to annoy you and if I have, please accept my apology.

I have see Bob's car and it is one of a kind. We are all luck that Bob shares his passion with us. He is the only one in the world doing what he is to a 964.
Thanks.....Bob

PS: I will be looking in your trash bin for your cast-a-ways.

Robert,
Although I respect KC's comments, I would like to join Edward, Martin, and David in encouraging further Rennlist posts on your interesting work - and I think a lot of us would love to see some of these components become available for purchase when the time is right.
If you need another "beta tester", let me know!

Thank you. I will attempt to keep you updated. And, to be sure, certain of the components have been beta tested (e.g., metal matrix composite wrist pins at 17,000 RPM for 24 hours) and others are being tested for a variety of potential applications including for future professional racing. And while cetain of them (e.g., the one-piece cast titanium upright pictured above) may not be in the budgets of certain racers, if you were going to compete with, for example, the Audi R8 (which I expect to win for the third time at LeMans), they would be virtually required. On the other hand, certain of the components might well be within a budget of a club racer, e.g., a true carbon fiber strut brace with titanium bosses costing, perhaps, $800.
