Talk:FORD SHELBY GT350R R3 SPEC/@comment-31462314-20180224001844

I have this car at PR 70.2, 25/29, 5353432 and according to RR3 Upgrade Strategy you need FU -2 Engine (5454432), which in my case, means at 30% upgrade discount investing another 55 gold to get back 50 Gold sponsorship deald AND an additional 29 Gold for 100% completion as per the page on the Ford Shelby R3 Spec GT350R World Series, so I'd say this is worth it.
