You should probably drive a new brembo GT and a performance pack '11 Gt500 as it will be night and day vs the older Gt500s. The boss will have stiffer bushings (although we don't yet know how far ford went) and should be another big step up control wise. I think the boss is going to surprise alot of folks. You may end up going poly but there us little to no chance ford went this direction for a number of reasons. The suspension is not about parts but rather development/ tuning and it seems that ford has spent a bunch of time making sure they have it nailed. Time will tell.

 

Humm first off the 2011 brembos GT dose not under steer . They change the lenght on UCA on the 2011 mustang it now longer . Here a video from MT iam sure most of you have all seen it already but i post it for the people that mite not seen it yet. If you watch this all the way through you see when he talks about the 2011 GT with the brembos he says one of the best thing about the car was it did not under steer.

So that were ford started at when they when to make the Boss so iam thinking in stock form it should been good . If you look at what ford did to the Boss they work on all the bad points that were in this video about the GT

 

The "brake dive" is what I saw from the car I saw at the track last month along with excessive body roll. I wonder if you add the Boss suspension improvements and adjustable dampers if that goes away?

 

The Boss suspension will act to limit dive somewhat, the front end is already lowered by 11mm. The stiffer Boss springs will limit the travel under steady state loads, while the increased damping will slow down the rate at which the car dives. Roll stiffness is increased both by the springs, and by the stiffer rear bar, though I doubt the rear bar will visibly change the amount of roll. It will make the front end bite better than the stock GT. Again the increased damping will slow down the transition into roll, so it won't be as pronounced during the corner entry phase.

****, I need to get myself back behind the wheel and onto the track again. It's going to be a loooong wait until Spring.

 

I thank all of you for the input. I thought occured to me that maybe the Boss LS could have similar suspension settings to that of the Shelbly gt 500 KR????? Is this at all possible?

 

I just can't imagine not needing some adjustable coilovers. I lowered my GT500 1.5" in the front and 2" in the rear. There still looks to be a lot of rake on the Boss photos I've seen so I would imagine it will benefit from lowering. Of course once you go there, then you'll need an adj panhard bar to re-center the axle and adj UCA to fix pinion angle. I'm leaning toward just pulling the trigger on the regular Boss with the Recaro/Torsen diff option that my local dealer has allocated. I am hoping to just buy the front splitter and rear spoiler from FRPP. The brake cooling kit is an easy mod.
