Lol. For spares I bought front and rear towers, arms, hubs, axles, castor blocks...basically bags from a kit someone was parting on the bay....I paid 224 shipped for my kit from Tower and paid 260 shipped to have a spare 1 of almost anything that could break.
Spares are going to be out of stock for awhile and this was my only option.
Sucks but "had to have" kinda deal.
