I only have 35k km (22k miles) on my 3 year old 10' RCSB 4x4,
and my front pads are due for replacement soon, within the next month or two (always do my own since I was 16)
... almost all fast City stoplight racing and hit the track on weekends.
I will also need a new set of 305/50R20 Terra Grapplers,
burned those off in just 3 years too.
