I am picking up a 520 next week. There are Couple left at a dealership in Dallas. In looking at accessories for upgrades (namely tires, skid protection) does anybody know if the 520 is different than the 500 (excluding the obvious) or are the subtle differences that will not allow the 520 to utilize same accessories as the 500? Lots of good information on the 500 but not as much out there yet on the 520. Any 520 owners figured out if the 500 components play well together? Do they utilize the same wheels? Etc. I know I want bigger tire size, probably 26”, seems safe for stock rims on the 500 but I don’t know if the same rim size holds true on the 520. Anybody going down this road with their 520? Thanks!
