If your set on getting an adjustable trackbar then wait until you install it and then see if it hits. I recently have seen a similar setup not hit the trackbar. 2.5" ome lift, jks trackbar, no diff to trackbar hitting. I would however go with the currier or jks as it seems to have the most clearance out of all of the adjustable track bars.
If you stick with the stock trackbar and 2.5" lift you should only be off about .25" which if you go to bigger tires later on will be better. On 35's and 2.5" lift there is nothing really on the passenger side to rub, but driver side you will rub on the steering box bolts. having it offset .25" will help on the drivers side.
Myself personally I dont want to raise mine higher than 2.5" of total lift, but if I was willing to do 3.5 I piece it together. I think 2.5" springs, 1" body lift, relocated shock mounts with 10-12" shocks, outboard the rear shocks, of course get the adjustable arms on there if you want them too.
