You really only have 2 options. Add a ton of cooling mods....and cross your fingers. Or ask for a full refund.....then either buy another car..... or continue modifying the 2010 Roush car. There is plenty of room below the Ford OEM tranny cooler for another cooler on your 2010.
The stick axle cars (05-14) don't have rear diff heating issues. I had the eaton / detroit tru-trac LSD installed at the same time as the WL watts link. The WL watts link comes with a new aluminum diff cover, with 5/8" thick flange..and new SS bolts. I bought a... 'lube locker' diff gasket....works superb, zero leaks. Some portions of the al diff cover are 80 mm thick.... to handle the 60 mm long bolts.... for the 'spider' assy. AL diff cover comes with magnetic drain + fill threaded plugs, makes swapping the gear oil a simple, fast job.
AL conducts heat 3X faster than oem steel diff cover. More overall surface area too. The eaton LSD uses either 80W-90 dino oil.... OR 85W-140 dino oil. You can't use synthetic and /or friction modifiers on the eaton lsd. I changed mine 2 months ago....and swapped from 80W-90 to 85W-140.
The watts link negates the short comings of a pan hard bar. I also installed a catch can on pass side of rear axle. Heavy 2 piece oem DS was replaced with a light weight, 900 hp rated aluminum DSS-DS ( 3.5" OD). Zero vibration on the dyno at 163 mph..(6500 rpm in 4th gear with the 3.31 rear gear + 27" diam rear tires. DS comes balanced from DSS to 9300 rpm.
If you opt to keep the new car and modify it, find out if the mods actually work...esp with the 10 speed auto.
