I have to replace my front pads and rotors on my 98.5 E1. I've gone to three different parts stores and they all seem to show different rotors depending on brand and/or whether it's a 98 or 99. Many manufacturers will list the part numbers for the other brands and you can see the pattern in the numbers. This just makes it more confusing as what one place tells it is different from the next. As you can tell, I'm lost and have to change these ASAP. Is there truly a difference between SVT and non-SVT rotors? How about between 98, 98.5 and 99 SVTs? Any tips to point me in the right direction would be appreciated.
