Need help with sizing rotors 2012 WK2 5.7

I'm looking at some EBC slotted black rotors with green stuff pads. My question is what size rotor is on the 5.7 with 20' wheels? Options are 330 up to 380 and dealer says I have 330. Can I install larger rotors? If so will it create issues with calipers? Is there a benefit with larger rotor?

380mm is the SRT8 rotor and you'll need SRT8 calipers or a custom caliper mount if you want them.

Stock for you is 330mm or almost 13". I have a used set in my garage right now.

Re: Need help with sizing rotors 2012 WK2 5.7

you might have 330mm or 350mm.. if your rear rotors are vented the IIRC the fronts are 350mm.

As far as I can tell the calipers and pads are different for the different rotor sizes and can't be interchanged.

You usually will only have 350mm with the tow package.

There are no airlines/compressor. They are auto load-leveling so the only appearance difference would be the top half is fatter than a normal shock and of course it's a different part number.

Example of nivomat shock.
