Not only is that excessive for an entirely street driven car considering OP stated they're never gona track, but girodiscs alone are more than triple any oem equivalent rotor..
It doesn't improve performance, at ALL, on the street. In fact, it could be worse, depending how those pads work. AND now he'd have to flush his brake fluid on an annual basis. Also: steel braided lines were super useful, back in the day. Modern lines hold up just fine unless under extreme conditions. Unfortunately, nothing on your list would benefit OP in any way. A track rat, on the other hand? Now we're talking.
Whether they are or not, they are great for track use, so will be more than suitable for the street. Many of us have tested them.I believe I read somewhere on this forum that upgrading the brake lines is unnecessary, since the factory ones are already steel braided, just with a rubber overlay. Someone can probably confirm or deconfirm this. I'm not going to cut up a perfectly good brake line to find out if this is true
You guys are replacing a two-piece rotor with basic rotors? Are OEM rotors that expensive? Such a bummer, but I totally get it. As long as the car stops LOL
The OEM rotors aren't actually 2-piece. They look like it, but are one continuous piece. I believe some trims of the Z4 have 2-piece rotors, however. The fact that OEM rotors from Toyota dealer sites are $200 or less a piece is further evidence they aren't real 2-piece units.
Ah, that must be what I was seeing while i was researching rotors this week (due for a replacement myself); if that's the case then my bad @kaj !
