If you want some carbon core 8.5mm in red (the best) check these out...
They may not fit into stock wire loom clip holders as they are thicker than stock, but I have used these superior wires before. If I remember they were $65 for the set and the quality was superior to anything I have ever seen before, radio suppression superior too.
You can order wire loom clips from them for the 8.5mm (not included with wires set I dont think)
Never have to worry about replacing the wires again with these.
