Just turned 50k..what needs replacing?
 

I recently did:
Both front lower control arms
Both front wheel bearings
4 new tires
Alignment
Driver's side CV shaft


I was also thinking I should do:
Spark plugs (currently original plugs) Any suggestions?
Brake pads/rotors (still original ones) Any suggestions?
Belts? (Mine are original)

What do you think, did I miss anything?

Plugs, I use Autolite copper

Rotors I use R1concepts drilled and slotted with ceramic pads, 4 years now and still a lot of pad left.

Belts, gatorbacks are OK, better then OEM, but I like gates belts from NAPA

Check over all your fluids, brake, power steering, trans, engine. Change the trans filter if you have not had it done yet.

Oops, yeah, I forgot to add that I just did the transmission fluid and filter too.

So when it comes to plugs, there is no advantage to platinum/double platinum or any of that crap?

If your engine is supercharged, you don't want plugs like that in the engine. My opinion is the plugs are over priced and only worth while when plugs are a major pain to change.

unfortunately I am not familiar with the short star, but I really don't know if its necessary to change the plugs just yet. most GM vehicles have 100K plugs and they are good realistically until 80-90K. I would suggest running a good-quality fuel system cleaner like Chevron Techron Fuel System Cleaner through the car and change the fuel filter.

Also, changing the air filter may not be a bad idea. Your brakes should be inspected for wear but if they aren't worn out there is no purpose in replacing them.

Hope this helps!

yep my gm plugs always last to about 100k too. but your car is getting up there i would take the wires off the coil and plug and check for corrosion and put some more dielectric grease in there. i would probably change the belt too just because its so important and hard to see wear
