G35 Couple with Brembo package.

OEM front pads lasted about 4 track days.

Porterfield R4S lasted 1 track day on the front.

Heard that Hawk was tough on rotors. True? Experience?

Does Ferodo make the OEM pads?

Looking for input from track day drivers. What kind of pads they use and pad life. Not too concerned about dust.

Thanks to all!

 

I do believe that Ferodo makes the OEM pads. I am gong to try Hawk HP+ front and HPS rear at the track next weekend and see how it goes. I don't plan on tracking enough to get a dedicated set of race pads, so hopefully the Hawks are a nice aggressive street/light track compromise.

Off topic... Since you have done a few track days, did you use the stock brake fluid? I am going to put in ATE Super Blue just to be safe but am curious how the stock fluid performed.

 

Have you thought about trying the dedicated race pad Porterfield R4-E? The R4-S are more of a street/autocross pad.

Other dedeicated race pads available for the Z/G I've heard/read of is Carbotech, Hawk Blue/HT10/HT14, Cobalt Spec VR, Pagid Orange.

 

Thank you for the info.

I use high temp DOT 4 fluid. Several good brands are available.

I live about 20 minutes from the track so I drive there. On rare occassions, take the car out for a leisure drive. My only concern with dedicated track pads is that they will not provide enough cold stopping power.

Anyone tried track pads on the front and street/track pads on the rear?

 

Oh, so it sounds like you don't change to a different set of pads just for race day and then change back when you get home. In that case, then no, race pads won't give you good cold stopping power on the streets. How did you like the R4-S pads for the track?

 

Your problem is tracking with non-race spec pads. High performance street pads are hardly up to the abuse of full track days. They are fine if you are new to tracking and not likely to be on the brake so hard. From the sound of it, that's hardly the case with you.

You ought to definitely consider swapping pads between track and street. It's a 15min. job for all four corner with Brembos.

Carbotech, Performance Friction, and Colbalt's all make pads that will stand up to all the abuse you give it and not especially harsh to the rotors. Hawk HPS is not particularly harsh on the rotor, but that is a street compound. I wouldn't recommend it for heavy track use. The HP+ is a light HPDE/autoX compound ... still not quite up to the full track abuse up front ... but enough for the rear. It is definitely more abressive to the rotor than the HPS, however.

 

did you change out fulid?

others, do you have opinion on if fulid change out is necessary?

 

Always a good idea to bleed and flush the brake fluids before a track event. It is also highly recommended to repeat the process after the track event.

Since his problem was chewing up pads ... it's not related to brake fluid.

 

The R4-S did not make it through 1 track day of 6 sessions. Very disappointed with them.

 

Thank you. I believe I might have to go that route.

 

Yeah, sorry to hear. I could of told ya that. The R4-S is not a 'track' pad ... the 'S' stand for street. The R4, however is a full track pad. It's a pretty lousy naming scheme from Porterfield.

 

Talk about reviving an old thread.

Anyone got a good source for the Carbotech or Cobalt pads?

 

No kidding ... grave digger!

Talk to Larry at Carbotech and tell him Clint refered you. You will recieve a 10% discount!

 

Thanks Clint. Good to meet you last weekend and thanks for the tip on the Carbotech pads. Hopefully they'll solve my fade problem.

 

Yup. All the other G35er that are now on it are all extremely satisfied at Spring Mountain. Good meet'n ya too.

Did you say you're on DOT4 fluid too?
