Dear BigJ “Josh”
SPC Performance (Specialty Products) has been in business for more than 40 years and has an outstanding reputation for standing behind its products. But as you can hopefully understand, due to the popularity of our products, the customer friendly warranty policy, and the number of counterfeits out there; we must also protect ourselves and our brand.
There have been several different reports regarding how many miles your arms have on them. We can tell by the picture that they were built and sold in or before 2008. There are many reasons why bonded rubber bushings will fail. However, even if you installed them wrong, (torqued the bolts while the car was in the air) our bushings would last much longer than 15k as you reported to the forum.
To your original question, we have three levels of kits for rear camber and toe on the 370Z.
Good; 72265 replacement cams will extend the range of the OE cams for both camber and toe.
Better; 72260 is an adjustable arm and a toe cam to give you max change and easy adjustment. The extended range cam will dial in toe.
Best; 72262 is a pair of Adjustable Camber arms, with lock out plates to make sure the OE cam does not slip, and two toe cams to dial in toe after the Adjustable camber arms change toe beyond what the OE cams can handle. This arm has an xAxis™ Sealed Flex Joint pressed in a forged steal receiver for maximum strength, the performance of a mono-ball and the longevity of an OE bushing.
