Toytec ultimate. New UCAs a necessity?

[sport05]

About to order the Toytec Ultimate next week. Do I need to spend the extra $400 on the upper control arms? I know its supposed to help with alignment, but what else are the advantages?

Thanks in advance!

New UCAs also provide more clearance for bigger tires and depending on the UCA brand, better articulation and droop.
