I'm in jersey and was thinking of getting radiator upgrade myself. I didn't. I just got gtm 25 row oil cooler with spal fan. During late summer at around 90F whether, my oil temp wouldn't go past 200 even if I tried. Unless you are tracking the car, radiator upgrade is not really necessary for our east coast temperatures. I suggest to spent that extra cash on good monitoring and then upgrade in the future if necessary. At least that's what I did
