930 2piece Rear Rotor

[bob barnes]

Want to know if there is a Market for a 2piece Rear 930 Rotor at a cost of $1650?
Barnes Motorsport has been trying to replace the rear factory rotors with a lighter rotor that does not support the rear brake shoes. Being trying to lighten up the former IMSA GTU-930 Chassis. Finally, we developed these direct replacement rotors without having to make any changes to the rear 930 Calipers. These are direct bolt on. Billet Hats with ARP hardware mounted to a rotor that requires no changes to your brake system. let me know if a 3lb weight savings/wheel has any value to you guys who are running 930 brakes?

Picture showing my feet shows a stock rear 930 rotor to the left and the two piece unit to the right.

Billet hat and steel rotor to save some weight. Expensive but trying to get rotating weight to a minimum.

I have similar set up from VCI i bought years ago can’t remember the price or the weight savings
But I’m sure it was a little lighter then the stock rotor

Blue,

Thanks for the reply. Checked VCI's web site and they show a price of $1850. for a similiar setup but I don't see a picture showing a cross-drill or slotted rotor. I do see a charge for $200 for Cross-drilling which would take the price to $2050.

No 930 Qwner interest in saving rotating weight on their rear end?

Bob, when I bought my 930 almost 20 years ago, on any given track day there was many air cooled 911s who would have been interested in losing 6lbs of unsprung weight. Today... meh. These cars are nosing into classic car status. Guys are still using them and modding them with aftermarket performance and comfort goodies, but not tracking the daylights out of them anymore or looking for that performance edge, at a pretty penny, and at the cost of their parking brake. Most of those guys today should push away from the table earlier and lose those 6lbs that way anyway.
I think here in 2020, you have a very narrow addressable market. My .02 cents, anyway. Good luck nonetheless- I’d be happy to be wrong.

Next set I need for the race car and I'm a buyer.

Perhaps if there was an option to retain the e-brake ??

I think VCI offers that as an option.

Otherwise, if my car was track purpose only, I'd be a buyer.
