[SVT ZX3]

I've heard plenty of good arguments for both, but I don't know if any of its ture or not. Here's some "supposed" problems... Soloted- major increase in break dust on wheels, does not disperse water very well. Drilled- very prone to cracking, can't be machined, but disperses water very well, but more prone to glazing over than slotted. Apparantly slotted doesn't glaze over because it cuts a new surface on the pad every time it goes over it. I don't know much about brakes either, but after reaserching this to death, everyone seems to have a conflicting opinion. I agree with Puppet, stay solid. The breaking on your SVTF is so good from the factory, I can't imagine any need to upgrade unless your attending open track events a couple of times a month.
