Default Why the rear?

I have my '93 at my trusted mechanic's for a tech inspection before doing a track day next weekend at Pocono. Car has 95K and has been well-maintained. I'm the second owner and have put 10K on it since I bought it last year.

Anyway, he only found two issues from the punch-list:
1. Rear shocks (FX3) blown (they are originals). Fronts are fine!
2. Rear brake pads low. Only 30K on them -- originals lasted 65K per prior owner records. Fronts were done 20K ago and are fine.

I always thought front brakes and shocks took more abuse than rears, and I never heard of rear pads going that quickly. Is it possible something else might be going on I should mention to my mechanic?

Thanks

check your handbrake lite could be off but they brakes could be hanging up a little easy to have checked

Also the calipers could be dragging, hoses bad internally can also cause drag or possibly they just put POS pads on.

I'm no expert but I think I read in a thread recently that the rear brakes do most of the work with ASR. Could be that competitive driving with the ASR on is eating up the brakes. Shocks could be old age and driving style too. If somebody can back me up on the ASR thing I'd appreciate it, if wrong tell me too.

If everything is working equally well, brakes should wear about the same. On shocks, it's not that unusual to see the rears go first.

Thanks, all

Majority of comments suggest that 30K not too bad for the rear pads on these -- smaller pads, possible ASR impact, more local driving, etc.

Mechanic checked out handbrake and Kid's add'l thoughts and no problems found.

Perhaps the prior owner just forgot to document the first rear pad change.

Anyway, off to Pocono next Saturday!
