Currently JKU '08 Sahara auto with tow package, 3.73 gears with Trac Lok LSD, use as DD, general off road, and some crawling

3.5 in RE standard lift with 33s, stock control arms, castor currently at 2.5 degrees (happy with highway speed handling currently)

If I upgrade to a Coast 1310 front DS next (as recommended by many here on the forum)

are there any later issues with an upgrade to adj. control arms (with what I assume would be a change in castor angle)

or an eventual regear and 35s

Thanks for your patience with newbie questions
