having some trouble bringing my car down from high speeds. yesterday i took the car for a nice highway run and there was a good stretch of road ahead so i put the pedal down for a bit got up to 150-155mph, when i started comming closer to the other cars i went ahead and applied the brakes. well by around 110mph it really didnt want to slow down any more. you could also hear the hum comming from the rotors. the wheels was fairly steady. on the other hand now, i was in my buddies evo and it stopped from 150mph like i was stopping from 75mph. im running hawk pads, stock rotor size and calipers, also stock brake lines. do i need better pads or is it time for a brake upgrade?

 

If you are just looking for more bite for braking, yes better pads will do it. I've said it before, and I'll keep saying it: Hawk pads suck *ss...

 

i would just like it to continue stopping, it seemed as if the pads didnt want to hold the heat. which pads do you recommed?

 

Depends on your budget. I like the Carbotech Pads. The Bobcats are a good street pad. Their old Panther+ now called AX6 is good for aggressive driving and AutoX, but still not a true track pad (should you ever do a lapping day).

I've had good luck on the streets with Bonez Stage I pads from RX7.com. Also, Porterfield R4-S.

 

Well, I'm not a fan of Hawk pads either but you have a mechanical problem of some sort to experience this. You don't need to "upgrade", you need to fix the problem. (Mechanical problem could be as simple as glazed over pads....)

 

i dont mind spending some to help the car stop. here is how i drive the car. weekends only, mostly normal, occasional 140mph+ pull on the highway. i just want them to stop from high speeds and not fade off the way it did. btw where can i find the carbotech pads? i did a quick search and they were only comming up for the dsm's.

 

I personally would take this time to "freshen", not necessarily upgrade, your braking system. I would go ahead and change out your brake lines (whether that's SS lines or new stock rubber lines), flush your brake fluid and use something more "robust" for that type of driving like ATE (Blue & Gold), and add in some better pads.

I wouldn't necessarily replace the rotors without examining them. Check for wear and see if they need to be replaced or not.

 

You can buy them from a few places. I get them from these guys: http://www.dpeweb.com/

They will be delivering the Carbotech XP8 pads for my M3 this week.

 

rynburg, any suggestions? i also figured it didnt seem right. what does it mean when the pads are glazed over? also how can i get rid of it. when i first installed the pads and rotors i did the bedding correctly. also why does it hum stopping from high speeds?

 

Hawk HPS pads are fairly easy to fade. I remember fading them with a single 130MPH stop. Try some different pads.

-Max

 

I would look at the Axxiss Ultimates also, those are really good aggressive street pads. Also, what tires are you running?

 

I'd also look into EBC Red or Yellow. The red's are marketed as their aggressive street pad. They can be a bit aggressive to the rotor material and will cause some grooving to the rotor. Personally I prefer the Yellow over the Red. The yellow is marketed as their race pad however it is perfectly acceptable to use on the street. It actually has better stopping power cold than the red does and only improves as they come to temperature according to EBC's own literature. It's a very rotor friendly compound and will not eat rotors.w

 

I am using EBC red and green..they are excellent, nice stopping power when I need it..

 

Given your rwhp, this wouldn't be a bad idea

I beg the differ. If he was actually running on a track rather than highway runs, maybe.

 

My tongue was partially in cheek....he did say he wouldn't mind spending some to help the car stop

 

ill give a new set of pads a try, if that doesnt work a set of stoptech's or racingbrake will be going in.

also rynberg i have potenza re750's on my 18's
