So...

There was a minor issue with the parts needed to upgrade to monoblock calipers found on the GS350. Adamsrotors.com have graciously offered to resend the order with myself picking up the tab for shipping. I look forward to receiving the items and getting them onto my car.

 

*EDIT: the custom has drastically changed the OP, so to avoid our replies being taken out of context, we have edited them.

in short, a GS350 is not a GS430...and therein lies the problem.
the calipers (and pads) are the same yes...but the rotors are not.
this is a custom modification for his GS300, NOT factory fit replacements.

the customer ordered rotors for the the wrong application he needed for is custom OEM+ upgrade.
the error was on his end & not the the fault of AR

we can make them for you, but it's not what you ordered.
and even tho we are made to order/final sale, I'm willing to accept return the GS430's you ordered, you pay for shipping of the new ones back, & I'll swap em out for you to make you happy.
