I found these on ebay. I was wondering if anyone had experience with these. If so what do you think?? Good deal? Good quality? Good fit? Good performance? Just let me know what you think.

 

honestly i wouldnt trust anything on ebay that has to do with safety for your truck but also look at the ebay page, their business phone is a cell phone number and they dont have any other number kinda weird to me but thats just my opinion.

 

Good point. Before I make any kind of purchase I do as much research as I can before I buy.

 

i know its tempting to buy them because they are so cheap but sometimes its better to pay a bit more and stay on the safe side

 

It it's too good to be true, it probably is.

If you are doing a brake job, then just get some new stock replacement rotors and some better than factory pads that give off less brake dust. If you after better braking performance (i.e. shorter stopping distances), don't bother. These crossed drilled and or slotted rotors do very little for improved braking, so little you won't notice a diff. You probably could not even measure a difference between them and stock. There are 3 things that will give better (shorter) braking, larger diameter rotors, larger surface area on the pads, increased clamping force from the calipers. Most big brake kits combine all 3 to improve braking, those cross dilled/slotted rotors are stock diameter, so they do nothing more than empty your wallet.

 

Great post!

The only advantage (sometimes disputed) of drilled/slotted rotors is that they may reduce heat-induced fading of your brakes.

I've also heard that they allows gases from braking to escape so more of the pad actually touches the rotor.

Uhh... whatever, tell it to the fart can crowd, they might actually believe you.

 

Most of the new pad designs take care of that problem, so that isn't even a big benefit anymore. I would spend that $300 on something else.

 

azfordby4,

Have you noticed a difference in stopping distance when you added wheels and tires??

It feels as if it's harder to stop my truck now with the new wheel/tire combo.

Should I look into a "big" brake upgrade? IF so, how much do these run?

 

Years ago, brake pads may have produced gases that would cause fade under extreme braking (due to the gases being trapped between the pad/rotor).

As years have worn on, technology has improved, and brake pads no longer create gas, even under the most extreme of conditions. Drilled rotors crack, and slotted rotors pose no braking advantage over a blank (or stock replacement) rotor.

Anybody ever noticed that F1 cars use blank rotors? No coincidence, folks.

 

The brakes suck and the rotors won't make a difference in stopping. I bought a set of drilled and slotted rotors for mine (all four wheels). They also came with those same Posi-Quiet pads, Let me add that I soon found out they produced just as much brake dust as the factory pads. I bought mine from G-Force Brakes in CA. The front rotors warped after 2 months and NO they wouldn't warranty them even though they stated when I bought them they have a 3 month warranty. I ask why and they said it must be the way I drive. I just had them turned last week and they seem to be ok. I don't usually turn rotors but I didn't want to totally waste my money if they could be saved. Anyways, I took the Posi-Quiet pads off and put on some ceramics, that made a difference in stopping for me. Far better than what it was like before with the simi-metallic pads and no more dust.

I won't buy my rotors through the mail again. That way if I have a problem I can go talk to the person that won't honer the warranty they say they give.

Here is the front

Here is the rear

 

I have these rotors on all four corners of my Firehawk and Formula (and had them on my WS6 Vert before I sold it) and they are just as good as any replacement rotor (factory LS1 f-body rotors are known for warping so I would say they are better than them.) Infact I beleive they are duralast rotors (autozone) that have been drilled, sloted and zinc plated. The only benifit to drilled and slotted rotors are during extream road racing type driving...the holes do allow them to cool better and the slots actually shave the pad to keep it from glazing over. So its possible the pads will not last as long and the dust will be worse with these rotors. With that set I have less than a 500 miles on either set and only had 2,000 on the ones on the Vert...so I can't speak to how long they will last.
The only reason I these on my cars because I like the way they look (and I needed rotors.) There is no other real benifit for them in daily driving.
As for the pads...I use Hawk pads so I cant say if these are worth a crap or not.

 

I have to staunchly disagree with you.

I went this [almost] exact route you speak of on my 2004 GTO [BAER Crossdrilled, Slotted & Zinc Washed Rotors which were same size as OEM, upgraded Ceramic Pads & PBR 2 Piston Calipers] and it DID make a difference. It wasn't ginormous, but, I tell you what, it was enough that I DID notice a difference in all braking conditions [particularly short], overall "feel" and I certainly COULD measure a difference between them and stock.

In fact, this left such a sweet feel on my right foot that I'm going a very similar route next week on my 2005 Lariat 4X4 fitted for all four wheels.

Frankly, I'm quite fed-up, disgusted and sick-n-tired with these bullsheet brakes that Ford have [literally] thrown on there to get these trucks out of the production line.

 

Ceramic Pads & PBR 2 Piston Calipers is why, not the rotors. I did the same upgrade as he is asking about with mine. I never upgraded the calipers like you did and It wasn't until I changed the Posi-Quiet Simi-Metallic pads to a set of Ceramic pads that I could see an improvement in breaking.
Just changing to drilled and slotted rotors are not going to make a noticable difference, you need better pads and those Posi-Quiets are NOT any better than stock pads.

 

I don't think the ceramic pads [alone] had a thing to do with the improvement in braking.

I've had ceramics many times in the past - as well as on my current truck - and a ceramic upgrade has done nothing for braking. It's always improved the brake dust problem [which was my reasoning for upgrading], but has done not a thing for the braking. Now, if you're claiming ceramic pads with other upgrades, then I agree.

I believe it was a combination of all things considered; but to claim that "crossed drilled and or slotted rotors do very little for improved braking" like 05RedFX4 did, well, I just don't buy that.
