January 24, 2011 - Here's our differential. It looks used because it is - it's the one originally used in Elvis. That car has a new rear end in it and this one landed in a box awaiting the Targa Miata. It's a Getrag rear originally used in the Cadillac CTS-V and has a 3.42 ratio and a Positraction clutch-type limited slip. It's a very effective package. tags: differential |
