+1 to surfingfreeman. This idea of vented rotors only being necessary for the track is the exact opposite of the truth. On the track you will not see any puddles (hopefully), which can quench (in effect, unevenly tempering) your hot brake rotors, potentially causing dangerous warpage. This IS an issue on the street, making vented rotors maybe MORE important on the street than the track, particularly if you enjoy spirited driving on twisties. Thus NO company makes street cars (or vans, or busses, or 18 wheelers) with solid rotors anymore, to speak of.FulviaHF wrote:I can’t directly answer surfingfreeman’s question. But I’ll say that Mark’s right that vented rotors make no sense on the street. Drilling and slotting doesn’t do much of anything there either, but I won’t argue with anyone who wants the boy racer look. Frankly, on the street keeping some heat in the brakes is usually a bigger issue than dissipating the level of heat that will fade the pads. And if retaining heat is the bigger problem, the very last thing you need are vented rotors that dissipate faster. So I’d say stick with solid.
@ Fiatmonkey: sorry, but (as maytag put less delicately) accusing a vendor of dishonesty isn’t any better if you do it indirectly.
Really, tell me Peterbuilt was thinking of using the boy racer look for marketing big rigs.
Or those 18 foot tall Dodge Sprinter cargo vans. They have vented rotors, too. Not drilled/slotted, but vented.
