Disc Brake upgrades

[offrovering]

i would argue that some cross drilled or slotted rotors work better, and could possibly even lengthen the pad life. the weight of a heavier vehicle can really benefit from brakes like this, then again, a lot has to do with the driver, but if you are a moderate driver on the brakes, you and your vehicle can benefit from cross drilled

Like I said before, unless you are hot lapping on a road course slotted or cross drilled rotors are pointless. You won't heat them up enough to need them.

You must not drive much,or tow anything.After a day on the trail I can see the heat waves coming off my rotors(god I need them lower gears and 4.3:1 t-case) or a trip with a 4000lbs trailer.When I do my SFA swap I'll have vented and crossdrilled rotors F/R with a hydroboost setup,at least then I'll have brakes(will need all the help I can get to halt a KJ that will weigh 5700lbs on 35" tires).

Towing I can see, I didn't think about that. But if you're just doing daily driving you're not going to notice a difference.

Some quotes from a friend on a race team (LG Motorsports):

Holes are for bling, and less unsprung weight. Nothing else. They are outlawed in most series because they do not last at all.

Powerslots are decent. DBAs are better. Brembo blanks are nothing like the rotors in the kits they sell.

If you want bling, get holes. If you want function, get slots.

Slots are for gas release only. Nothing more. They do clean the pad a little bit, but thats it.

There is actually a layer of material that is expelled between the rotor and the pad. Slots get rid of this.

Slots do not eat pads at a rate any quicker than any other rotor.

Vanes do the cooling, as well as some highly engineered Hats and bobbins.

The amount of vanes per rotor is soley dependent on the type of application.

Race car has slots only. Had drilled in the rear, but oh, they Kept cracking!

They provide a path for the gasses. That can be accomplished by the slots too.

Better wet braking? Water doesnt build up on rotors son. One stop in a 3 mile trip will get them warm enough to burn off any water.

Porsche runs them because the are heavy, and no they dont last in racing.

This was from a slotted or cross drilled debate when I was at Purdue 3 years ago.

Yes crossdrilled rotors don't last as long,under repeated high speed braking and they are not just for bling.But under low speed braking,I'll be only doing maybe 5mph) there is a added benifit,the crossdrilled holes expose more surface area of the rotor which helps in quicker cooling since I'll being going to slow for the vents to have any cooling effect.Non-slotted and slotted rotors will take more heat but will also take longer to cool.After my SFA swap 70mph is going to be the fastest my KJ will ever see and I'm not to concerned about cracking a crossdrilled rotor under low-normal speed halts(a very slim chance it will ever happen).


But I will say they sure do look pretty,and yes in the right appilication they have great benifits that outway the negitives.
