Brake rotor choices... which one? - Page 2

JL1RX7 · 06-28-2008, 04:07 AM

So far I have not noticed any cracking or the like on mine. My car is a DD not a track car so I know the rotoars are more show than anything else. But What I have noticed is a sharper intial bite, shorter stopping distance and better brake pedal feel. I did the SS brake lines, new master, new fluid, Hawk HPS in front, ceramic advance auto pads in the back. So other than rebuilding the calipers my system was reworked.

So you're telling me that brake fade or "gassing," as that guy calls it,is no longer a factor in modern (60s+) cars? I don't believe that for one second.

Everything I've been reading the past couple of days (trying to reach a decision on what to buy) agrees with that guy saying gassing really isn't a problem anymore.

You're allowed to believe whatever you want to believe.

What is indeniable is the fact that drilling removes metal.
Removing metal lowers heat capacity.
So you have the same amount of heat going into less metal.
This just concentrates the heat more.
This is how heat risers and cracking develops easier.

If you want to pay for cross-drilled brake rotors, go right ahead.
It's your money.

I think I'm just going to go with blanks.

I went with the Beck Arnley's. I hope they work out because they only have a 90 day warranty, compared to the 2 year on the Duralasts.

i got the slotted rotors from rx7store.. i cant tell much difference from stock, but im still breaking them in, so no really hard braking yet

My5ABaby · 07-02-2008, 08:05 AM

There's a need to break in slotted rotors?

just seat them though, right? Get up to speed (25mph) and brake fairly hard to get them seated. Or is there another procedure that's more appropriate?
