slotted rotors only! They said they would never run a cross drilled rotor as they are prone to cracking. So, i guess if slotted rotors hold up to the abuse they get on a race track, they may be good enough for my dd truck.

parabola said:I'm curious though as to why you need slotted rotors on a DD truck?
clownmidget said:Is there such a thing as too much braking ability?
I'll admit not yet pricing 80 series slotted rotors, but drilled or slotted rotors for my Supra were way higher priced than stock.clownmidget said:Well I dropped the coin, and I can say that braking is improved considerably over the OEM setup. Immediately prior to my purchase of the truck the previous owner had Toyota put in new rotors and pads so I bought the truck with about 1K miles on them. Once it was time to do the front axle rebuild I went with DBA's front and back and some Australian "performance" pads that came with them. That was a huge difference. Since then I've added 100 series front pads. Again, a nice and noticeable gain in braking performance.
I don't think the costs are entirely out of line with what new OEM stuff is either. Bottom line is that these are very heavy trucks and even though the speeds aren't as great (in some cases!) I would think the added mass really puts the braking system to task where venting hot gases and not boiling your fluid comes into play.
parabola said:I still don't think slotted rotors are worth it for trucks that are not extremely hard on their brakes.
Actually, I live in a region known as the 'Hill Country', a metropolitan area of over 1 million people, and it's TX so of course we are have plenty of lunatics.clownmidget said:And that's my point. These trucks ARE extremely hard on their brakes. I guess you may have a different experience, live where it is less hilly, less traffic, less stop lights, less lunatics continually cutting you off, or just drive it very little except for weekends, excursions, etc. But start driving one of these daily in typical big city urban traffic coupled with the general topographic relief of southern CA and you WILL go through brakes quickly and become intimately familiar with the limitations of the stock setup to the point that you start looking for larger diameter rotor/bigger caliper kits.
Gumby said:Two guys I know run cross drilled slotted rotors on a 80, and one on a 4Skinner.
All experienced very fast warping. None are happy.
Small sample. YMMV, literally.

Boston Mangler said:I ran the DBA cross drilled and slotted rotors on my 60 and loved them, no problems!
I can almost ASSURE you you friends experience warping and cracking are using cheap brand rotors! DBA's are made for abuse and are top notch!
