Nope, I've done about 20,000kms on my ds2500 and OEM disks and they fantastic. The first braking application of the drive is a little lifeless, but after that they are perfect... They only take one application to warm up and then they bodgy.. But cold or hot they rock.
Even when cold they'll stop you fast enough to rearrange your eye balls.
I'd suggest though that you apply copper grease or similar to the backing plates that will eliminate any squeal.. And if you do opt for them, make sure you bed them in as per the instructions - about ten hard stops from 60 mph to 5mph in a row. This will transfer pad material to the disks and takes them through some heat cycles.. during bed in, don't come to a stop, that will apply uneven material to the disk and cause brake judder.
They wear well too, I've used about 50% over 12,000 miles and they seem to play well with the disks too..
