GXP needs rotors - fbody applicable?

I've been searching and searching. Have yet to come up with much info.
I have an 07 GXP that needs brakes for the second time in 50K miles. GM really screwed something up.

Is this 12 inch "upgrade" to f-body brakes relevant to me? I'm seeing that the stock GXP's are a bit over 12".
I can get rotors for any one of my f-bodies but seem to be having trouble finding a decent price for the gxp.
Would the caliper bracket from say an 00 TA be all i'd need to fit the TA rotors on my gp?

Hopefully. Because I can get all 4 zinc coated drilled and slotted for ~$328.
 


Nope, they are definitely smaller rotors, 11.9" vs 12.7", IIRC. If you REALLY want to downgrade, you'd need the calipers and brackets, just like everyone else.

If you're going through rotors that quickly, there's something going on. Are you using a torque wrench on your lug nuts? Washing the car when the rotors are hot? Sitting with your foot on the brake after stopping from high speed? Seasoning the rotor/bedding the pads?
 
your GXP brakes are 13" (really 12.9)


I wouldnt recommend the F bod brakes because of the different pison size of the caliper, and that will give you a mushy pedal feel

ZZP has the GXP replacement rotors for a reasonable price
 
Right. Stock GTP 10.9 F-Body 11.9



If you need some decent priced rotor's I can give you the best price around.
 
I'm not doing anything different with the GXP then i'm doing with any of my other cars regarding the brakes.

At 40K miles, the rear left went from 1 squeak to grinding the rotor in 1 day. Those got replaced by GM with just a purchase of rear pads. I changed the fronts to Hawks HPS about 1K miles later.

Now at just under 50K miles, all 4 rotors are grooved, the crossdrills keep getting filled, they always have rust on them, and the rear left just started squeaking again.

About the only good thing about these GM rotors is that they're not warped.

I didn't see any GXP rotors listed at the ZZP site. You'd think these things were made of gold with some of the prices that i've found.

Your link lists the fbody upgrade which apparently I don't need. What can you do for slotted/drilled/coated stock GXP sized rotors?
 


That's pretty typical on those rotors. The brakes on those cars are ususally only good for 20k to 25k, and the rotors are then worn beyond the limit to remachine them. The rotors are soft or pads harder than most cars. They really wear out fast!

If you scroll down to the bottom of the first post you'll see where I mentioned the rotor's.


I'll get you some prices

If you're rotor's have grooves in the then you either have a pad problem (defective) and that is what caused the grooves or the pads were not changed soon enough and were causing metal on metal contact and wore grooves into the rotor.
 
Prices for you're car for front and back cross drilled and slotted with zinc coating (prevent's rust) with a lifetime warranty shipped to you're door is


473.02


I will beat anyones advertised price.

After actually looking these up for a customer for the first time, I must say, They do seem awfully high in price.

Personally I think the rotors are crap. Obviously the car came with stock GM pads. GM threw on new rears with a new rotor. I changed the fronts to Hawks HPS before they were needed. All 4 rotors now need to be changed.
When I say grooved I don't mean as in a rivet digging into the rotor. I mean more like a picturesque rolling hill scene. They're not flat but rather have smooth transitions from the lows to highs.
 
Do the rotors that you're looking to sell me look like the ones on the bottom of your ebay store? 2 sets of cross drills then a slot, repeat?

Sorry not sure why I was not subscribed to this thread. So sorry for the delayed response.


Correct. What you see in the pic's is what you get. I also added the regular slotted ones in the store. None are for you're model but I will be adding those soon. There's a lot I still have to work on regarding uploading stuff to the store. So I appoligize.


But again if you have any other questions please don't hesitate to ask.

Oh ok. So it's more of a warping type issue rather than what I was thinking of.
 
I don't seem to be subscribed to my own thread either.

Lifetime warranty? Against grooves not caused by rivets?

Do you paypal? If so, send me an invoice to [email protected]

Not a warping issue. It's almost like there are soft lines in the rotors. There is no pulsing of the brakes. They don't clean up with brake useage and they are not smooth from running your finger from the hat to the perimeter. It's up and down all the way out.

Apparently the Hawks pads are eating the fronts for breakfast as well.
 


Have you tried having the system flushed? You might have some air in the system causing some uneven braking maybe? I am by no means a brake expert but it seems like common sense. That and the fact that Hawk pads I thought were pretty rough and were meant to be beat on at the track...not for everyday street driving...

Yes I do paypal. Lifetime warranty against rotor defects. That includes warping.


Wich rotor's do you want me to quote you on? Drilled and slotted or just slotted?]


I would suggest going with a semi metalic pad. Those would give good bite on the rotor's and would also be easier on the rotor's.


Most of the pads with the exception of a few that offer a lifetime warranty for pads are ceramic. Wich basicly means longer pad life and shorter rotor life.



I sent a duplicate message to you're Email you listed above. Just respond and I can get these shipped out as soon as you pay.

If there was air in the line you would be able to tell. You would have a mushy pedal along with no brakes.



Hawk pads are pretty tough. But I would not recomend them.
 
I have them on my street/strip car to no ill effect.
I also installed them on a daily WRX with no problems.
Hawks that is.

No air in the lines. Been doing brakes for ~15 years. Simple really. I don't understand why brake shops try to rip people off so badly.
