I need to change the front pads on my 01' SS. The car has just over 40,000 miles on it. Do I have to put new rotors on too ? How can I tell if they need to be changed ? Since the car has the slotted & drilled rotors would I need to buy those somplace in particular, like from GM ?

Also any recommendations on pads ?
thanks.

I always change my rotors along with my pads since they are pretty cheap as it is.

no, you don't have to change the rotors. only change them if they are overly warn, warped, or cracked. DEFINITELY inspect them thoroughly for cracks since they're drilled and slotted, especially if you track the car or load the brakes up a lot. if the rotors are ok, you just have to bed in the new pads well before any serious use.

Agree. If you don't get vibration while braking and see no cracks, the rotors are good to go.

You should atleast resurface the rotors when installing new pads. Also make sure that the rotors are not below minimum thickness.

Here's the specs for the rotors:

Front Brakes

Rotor Discard Thickness*
30.7 mm
1.209 in

Rotor Maximum Allowable Lateral Runout
0.06 mm
0.002 in

Rotor Maximum Allowable Scoring
1.50 mm
0.059 in

Rotor Maximum Allowable Thickness Variation
0.025 mm
0.001 in

Rotor Minimum Allowable Thickness After Refinishing
31.08 mm
1.223 in

Rotor Thickness, New
32.0 mm
1.26 in

thanks guys. I was going to do this before I headed to the dragstrip next weekend but I don't think that will leave me enough time to bed in new pads.

Where would be the best place to get the same rotors I have on the car now?

Drilled and slotted rotors are good for nothing.

They aren't OE if thats what you're thinking

And they don't stop as well and plain rotors

If you really want to do yourself a favor, get brembo blanks or upgrade to a Corvette C5 conversion.

What makes a disk brake work is diameter and surface area. More diameter gives better leverage. More metal (by way of fewer slots and holes) actually dissipates more heat. The holes and slots don't do anything but wear down your pads quicker and make the rotor prone to failure.

I'm not sure of the exact rotors you have, but any parts store should have the stock replacements.

Many of our sponsors --> will have OE-sized upgrades, which is likely what you're currently running. They also sell plus sized upgrades and more.

I always turn the rotors when replacing pads. Just take the rotors with you to the parts store. If they cannot be cut, replace them.

This saves a ton of greif, time and effort. Do it right the first time.
