We are.

 

What inherent problem?

I have EBC Yellowstuff on my XJR and I cannot fault them. And I have hammered them at the track. They just need to be "burnt in" I mean the first session out cooks them and they fade out, but after the first heat cycle they are fine, have taken plenty of abuse.



I also have the EBC Redstuff on my Land Rover, and ran Redstuff on my old X-Type as well. I'm very happy with EBC pads.

However, I do think that EBC brake rotors are pathetic and I would not touch them with a 10ft pole. They are awful things. The rotors in that pic are from R1 concepts, but it seems they are not offering their "Premier" rotors for the F-Type yet...

Just my 2c...

 

Since there currently isn't a decent track pad for the V8S, the EBC Yellowstuff will have to do. But once something comes out that's better, I'd recommend staying away from the EBC.

The inherent problem with the EBC is they have of mu of 75% within the first 200*F of operation. IOW, from 400*F-600*F, torque drops off 75%. A track pad needs to have a mu of less than 10%. Carbotech, PBC & Pagid are examples.

Also, while EBC claim a maximum operating temperature of 1400*F, independent tests show they have a maximum effective temperature of 1200*F. A true track pad needs to operate effectively up to 1600*F.

This is all from my brake engineer friend who has designed brake systems for many Continental Race teams, championship winning Daytona Prototype teams & many, many others.

Surprisingly, the OEM pads & brake fluid put up with a decent amount of abuse this weekend. However, I did not drive her as hard as I would have my race car. When I left the TrackDSC on, it overheated the brake fluid & I ended up blowing through a brake zone on entering at 116mph. This is because I was over-rotating the car so often & making the DSC intervene so much, that the brake fluid was boiling even before I tried to do any braking. Once I turned off the DSC completely, I didn't have any more brake issues. And then the hooniganism REALLY started.

I've come to the conclusion that this car is a really, really good street car. It is a hoot on the track but not a very good track car. It's a hoot because you can hang the tail out at will & for a loooooong time -- if you know what you're doing. Trying to make a fast lap is difficult because it is very hard to get the power down without having the rear step out. While power sliding is fun, it isn't fast. But it also garnered lots of attention from even the most jaded track rats. Everyone came over to take a look at the car &/or ask me how she was on the track. And everyone though the exhaust note wa just simply glorious.

 

Yep . . .

 

From everything I've seen the AWD models with carbon ceramic brakes make the better track cars. The RWD models have the issues you mention with traction and the standard brakes aren't really ideal for track use.

However, the FTR isn't really meant to be a serious track car, IMO. I thought about this quite a bit before I purchased my FTR since I was debating between the FTR and a 911 (GTS or Turbo.) I came to the conclusion that the F-Type is a great street car that works well on a track, while the 911 is a great track car that works well on the street. Since I care more about street use than track, I ended up with the FTR. They're very close other than when you look at track performance (where the 911 wins) and road comfort (where I felt the FTR wins.) Either way, the FTR exhaust note blows everything else away, and it looks a lot better too, at least in my opinion.

I will probably take my FTR on the track at some point so I can legally open the throttle more aggressively, but only for fun. But I won't be taking it to far to the extreme, particularly since I didn't go with the carbon ceramic brake option.

 

It seems like you have done exactly the same analytical evaluation as I have done, and come to the same conclusion. That was the reason I chose the F-type R rwd.


After almost one year of ownership, but only half a year of experience (due to the long and cold winter where the car is not being used), I have only been strenghten in the feeling that my conclusion was the correct one for me.


However if my intentions had been to regulary track the car and/or use it during the winter, I think the awd with carbon ceramic brakes would have been a better choice.


And if my intensions had been to regulary track the car in order to set the best possible track times, I think a 911 would have been a better choice.


But I am still very happy with the choice I made, and I would have done the same again

 

To be clear, I only took the V8S on the track to explore its limits. I don't plan on tracking her regularly as I have a dedicated race car for that. I wanted to explore & learn her limits in a safe & "controlled" environment. The best place to do that, IMHO, is the track.

 

That's not just IYHO, that's just plain common sense (which too few have).

 

I very much agree, and this is also the main reason for why I will take it to the track once or twice.

 

Happen to be lurking around the F-type/XE/F-Pace forums today and figured I would post some of my thoughts..

I agree that EBC Yellowstuff pads are not really track pads, but they can withstand the abuse better than some OEM pads. Eventually they'll get too hot and melt or crumble into pieces. I've read this on multiple forums and proved it to be true after tracking my 3700lb car (non-Jaguar). They can tolerate some heat but they don't perform nearly as good as true track/race brake pads anyway. The jump from OEM to EBC Yellows was OK, but the jump from EBC to track pads was astonishing. The nice thing about EBC is that they're one of the first companies to offer pad fitment on newly released vehicles AND at a very reasonable price. Just my honest opinion, take it with a grain of salt

If you're only going to occasionally track your F-type maybe it's not worth the hassle of changing pads. You might be OK running the OEM parts or a cheap alternative like the EBC Yellows. Just keep in mind that Yellows might be rough on your rotors.

I ran into a similar issue when trying to find track pads for my car last HPDE season. Performance Friction, Cobalt, and Hawk didn't have fitment for my vehicle. Luckily, Carbotech can make "custom" pads to fit any application so after a long wait I was able to get pads from them. Unfortunately, I can't compare their performance to Hawk or Performance Friction, but I can say they worked well for me! I've ran XP10/XP8 and RP2/RP2 compounds. XP compounds were VERY rotor-friendly (better than Yellows), were quiet driving to/from track, and had great bite. Based on my experience at Mid-Ohio and Pitt Race Complex. Not affiliated with Carbotech, but I would recommend at least looking into them if you want a more dedicated track pad. Hopefully that helps,

Any updates on the hunt for good brake pads? Mine area already toast (less than 7K) and I need to change them. I really don't want to have to put the OEM ones back on....


2015 V8S Convertible with none carbon-ceramic brakes...

 

Have been researching this & have found the following: Our brake system is by Bosch. As such, there are very few aftermarket pads made for anything Bosch as the majority of "performance" brake systems are Brembos or variants thereof.

As stated above, EBC are not very good pads. I'd stay away from them.

Found out this from my brake guru -- the reason Carbotech can make custom pads is because they start with a sheet of Hawk brake pad compound. They then make a backing plate specific to your car. Then they cut the pad out of the Hawk brake pad sheet to match the backing plate & then RIVET that to the backing plate. This is why the Carbotech pad only lasts half of the thickness of the pad before it starts to fail.

Hawks, in general, have a better mu & performance than the EBC. But the Carbotechs won't last as long as you'd expect given how they are constructed. If you can get Carbotech to make you a custom pad, I think this would be the way to go for a track pad.

If you're looking for something just for the street, OEM is your best bet at this time.

(About the Carbotech technology, this recently came out bc 2 of the last 3 employees for Carbotech have been looking for jobs in the brake industry with the recent sale of Carbotech to another company. Both of those guys approached my brake guru for a job & while talking to him, told him how Carbotech made their custom brake pads.)

 

Porterfield ...:: #1 Race Specialist in The World :: » 949.548.4470 will apparently on a "made to order" basis with a current lead time of 7-10 business days provide pads.
I contacted Wendy Chatlier there today and she provided that info.
Their web site gives a good description of the pads they sell....I use them exclusively on my Z3 MCoupe ( 3400 # +/-). Don't know what would work best on our cars.

 

Not a track experience but for the second weekend on the Dragon with the F-Type this year. I have to say how amazed I am by the performance brakes on the V8S. Never had fading or lack of initial bite. The E-Diff locked up before we had any brake issues. We had many cars end the run with smoking and crackling brakes from obviously over driving the car. The F-type was one of the heavier cars and as I stated I had no issues with the brakes. I forced an M3 to pull off with my presence in his trunk and completely filling his rear view mirror and than almost ran a 911 off. Of course this is not at track speeds but with over 100 turns in 11 miles and half of those down hill it is taxing on the brakes.

Maybe I am not serious enough track driver, but I never felt that upgraded brakes on my V6S were in any way inadequate.
