Josh reminds me that the Blues are brutal on rotors. The HT-10a are easier on rotors but they're still not what I'd call "rotor friendly".
Good brake pads are expensive - there isn't a way around that. Having said that though, be thankful you don't own the newest version of the RWD Beetle - pads for those cara are in the $300+ range. - Matthew - On Jun 25, 2012, at 11:24, Chad Rebuck <[email protected]> wrote: > Thanks Matthew, > > My gli is a street car, but I don't really drive it a great deal anymore. > I have managed to rack up 4000 miles since finishing the engine rebuild > last September :) > > Wow, I checked out the price of the dtc-30 pads and they are just over $100 > for the front.
