Thread went away. Don't know why... I wish the error message you get when you go to a hidden/deleted thread or whatever said why it was hidden or deleted.

My experience has been that there are adequate offerings in the front and rear to assemble a balanced program for whatever arena you are campaigning, however, the center diffs offered off the shelf leave a lot to be desired when it comes to building an extensible system that can scale well across environments. I run an S5 rear with the gold wrapped N11 center; this plays out pretty well in most environments. Notably it is the center diff that brings the system together, whether I am running Cusco tarmac, the Prodrive S5 or otherwise.
The N11 center makes use of extensive slip control functions in combination with gear-based mapping functions allowing the response of the center differential to be better tuned for both under-steer / over-steer control as well for corner speed.
The result is that the center diff control is optimized for a greater variation of corner types, i.e.
– being relatively free in slow corners to aid turn in but locking up quickly to aid traction out of the corner, having good response to over-steer/under-steer in medium speed corners and free again at high speed to reduce transmission drag on the engine ( this is an important conditional that has been missed by this thread thus far ).

The whole system is easily controlled, from the cabin, via a thumb wheel.

My current set up, per PD:
Position 1 (lowest ladder light – green)
· Road position - center diff free
Position 2 (second from bottom on ladder – green)
· Basic slip map equivalent to standard N11 position 4
Position 3,4 & 5 (3rd 4th 5th lights from bottom – orange)
· Gear based slip maps!!!
Position 6 (Top ladder light – orange)
· Center diff locked

The controller is a Pectel unit that can by managed independent of the Prodrive maps as well. A relatively inexpensive implementation would be a simple Cusco front and rear set up, stacked to your needs, and managed by an N10 or N11 center.

I am looking into the options for specifically for a Street Prepared Subaru

What options are out there?
Guess it depends on what diff you want to replace....
for the front...there are Helical, Suretrac, 1.0, 1.5 and 2.0 LSD's out there...

What are the advantages of either???

As for the Center diff..I Know there are about 3 different choices for the 5 Speed and couple of more for the 6 spd...

there is the factory Viscous 5kg Center diff, there is a Viscous Gymkana 12Kg center and a OMG Viscous (rally) 20KG Center....there are also options for the DCCD... with different lock up points....minotaurfightstore | minotaurfightstore

The Rear also has alot of options....along with the factory viscous has a 1.0, 1.5 and 2 way option also....

What would be the ultimate setup for tarmac....
how about AutoX....

What would be the ultimate front/rear bias????

thanks...I hope this stimulates some good discussion......

right now...my SP Setup is:

-Helical Front diff
-Gymkana 12KG Center
-Factory Viscous Rear

Plan is to swap out the rear with a mechanical 1.5 way LSD...then I should be pretty close to where I want to be..

Bill

Really cool. You can make everything good. I LIKE THE Narration.
