Are the cheapest rear rotors ok from supercheap

[GK813]

I need to buy two rear rotors for my VS ute non IRS and the cheapest one from supercheap is $49.99

There's not much spec difference from the more expensive ones except a 3mm height difference so are these rotors good to use, has anyone used them but found they wear out too fast and rust out?

Personally i don't know the brand Guardian but it would be a SCA brand like ToolPro, so it is up to AU standards.
I would say use them as standard replacement but if you are a bit of a rev head they will prob warp, buckle or break under extreme use.
They prob will rust on the hub and sides a bit as they have not been coated for that price. Simply use some black paint to protect them a bit longer.

For $49 try it and see.

I got mine from these guys in keysborough 3 years ago , haven't had a problem. Also on ebay.

If they are spec'd for the ute ..use em... theyre brake rotors and they are rears..so wont be doing as much work as the fronts . Just check the 3mm doesnt cause any problem run the wheelnuts in to firmly hold the rotor in place and fit the caliper check theres sufficient clearance by spinning the rotor... one thing I did notice about cheaper rotors is you can sometimes get brake squeal for a few weeks to a month while the pads bed in (fronts usually...old or new pads makes no difference).... it does go away...just a pain in the butt for about a month sometimes...you can get pads that have a composite that speeds up bedding...but they tend to cause the disc to wear out faster...

I was on the phone with supercheap and I decided to buy the next cheapest ones for about $80 but guess what even the guy on the phone said using their website is problematic at the moment me and him couldn't find the ones I needed on supercheaps web site they all showed for IRS, mines not IRS but he could see them on his buisness pc, I couldn't buy them online because they just didnt show in a search soooo with his help I bought a $50 gift card online to use as a deposit because they need the buyer to pay for them first he was very helpful and I'll pick them up when they are at the store
