cross-drilled rotors & pads

[smokesho]

i have a place near me that will sell a front set of properly done cross drille rotors and their pads for if i remember correctly, just over 300 cdn does that sound good to anyone, or atleast average? i thought it was o.k. and i don't have to pay shipping as if i ordered from someone a thousand miles away

 

[94shoboy]

that sounds like a great price to me. i would do it for that cheap.

Anybody else want to see these cross-drilled pads?

That's a lot of money for neat looking rotors, but it isn't going to help your braking performance. High performance pads? Yes, that will increase the braking capability. Performance Friction Carbon Metallic pads will give you a noticeable braking performance increase for around $30 and a lifetime warranty. You may wnat to read the post on the Big Brake Myth and save yourself a few (hundred) bucks.

i do know for a fact that they help to dissipate heat quicker and more efficiently because of the increase in surface area. and i may be wrong but it's not a whole lot over the stock parts price is it???

I bought some cryo treated rotors and CM pad for the front of my '91. My braking performance increased greatly. Cross-drilling is for looks. Gassing was a problem with organic pads of the past. I know Porche, Ferrari etc have cross drilled rotors stock, but they are for looks too. Vadim once showed me a pile of cracked cross drilled rotors from SHO's. Cross drilling can help cool solid rotors, but just weaken vented rotors.

but when done correctly, the cross-drillling should not weaken the rotor to the extent of cracking.....maybe i'll get mine cryoed, i knew a guy a while back who was in sales for a cryo company.

Cross-drilling removes surface area of the rotor for pad to rotor friction contact. The purpose of cross drilling on very high performance cars is to allow the gasses that are created by very high pad temperatures to escape through the holes rather than interfere with the pad to rotor interface. The holes are not designed primarily as cooling holes. You really should read the "Big Brake Myth" topic.

Here's the url to CyberAuto's page on SHO stuff - note the KVR drilled or slotted rotors and carbon fiber brake pads.... I ordered a pair of the '96 rotors with pads to try the upgrade on my '95.

 

[smokesho]

cross drilling does increase the sirface area for cooling of the rotor which can help to keep compnents cooler, and if you increase the friction on the rotor and therefore the heat under braking this could be desireable......aside from looking neat.

Cross drilling will help braking so will bigger brakes reguardless of what whoever said that started the "Big Brake Myth" because the more brakes there is to stop, the faster you will stop period. Granted the tires help but what is slowing down the tire other than the friction between the tire and the groud but the f-ing brakes. Bigger most times better.

actually....simply put that is true.....bigger is usually better... however efficiency as sdpatt has been refering too indirectly is also key! on a slightly different note.....and i could be wrong, but i know slotted rotors eat pads quicker because they increase the friction because of the slots.....so, would it not stand that cross drilled do this is a milder way. because even though the edges of each hole has an integrated surface the friction should increase...???
