Here's the finish to my XR2 story: Installed the XR2's in mid-September. Replaced them today. Pads worn to the backing plates, rotors trashed, and my local car wash is looking for stronger acid to get the caked-on dust off my rims. 3,000 miles and 3 track days total.

BTW, this is simply my report. It is not a complaint against Cobalt Friction, their fine products, or the terrific people that work there. They were outstanding pads at the track.

These just are not run-them-all-the-time race pads like the spec VR were or XP-10's are. I'm going back to the XP-10's because I'm too lazy to change pads between events.

Happy New Year to all of my friends on this board. I look forward to seeing you at the track this coming year!

 

Hey guys. Thought I would bring this one back to life.

I've been working with Andie recently about tooling new backing pates for the J's Racing / Endless 6 POT calipers. This would finally give owners of these kits a wide variety of options at a much cheaper price and with out all the down time!

Click the link below to find out more information about purchasing pads or just show your support so that Cobalt knows that there is other potential buyers for this particular fitment out there.

I will also be doing some testing to figure out the best combo for this type of set up. Starting off with matched F&R XR2 set as a baseline. I'll move up or down in the series depending on whether or not I feel the rear needs more or less bias to compensate for the front calipers. Hopefully we can get all the bugs worked out quickly.

Thank you!

 

stock rotor size /caliper compatible?

 

He is speaking of having cobalt do a run of pads for endless/j's 6 piston calipers.

To answer your question, Cobalt makes a variety of pads for the stock brakes.

I personally use carbotech's and cannot say enough positive things about them.

 

That is correct. Cobalt makes applications for the stock caliper / rotors including GT-Sport, XR4, XR3, XR2, and custom race compounds as XR1 and XTR can also be ordered (if needed)

A proven set up for track applications would be to run XR2 Front and XR4 Rear. If you read through the entire topic you see that people have tried other compound and set ups with great success



I figured it was about time a U.S manufacture step in and help us out. No matter what peoples opinions of BBKs are....Those who own them will be able to acquire any compound of their choice and have the ready in a timely fashion and lets not forget the cost.
Pad choice, selection, price, and wait time from Japan is enough reason not to own one. However thanks to Cobalts help there will be more options for Endless / J's Racing owners

Please forward other members this link and help spread the word.

Just an update here: after going through a few sets of XR2s, I went back to using Carbotechs. Why? Fading problems. I routinely had fade issues with the Cobalts. They would just go away about 20-25 minutes in.

I used the Carbotechs for years, and then decided I ought to try something else just to see if there are better solutions out there. I decided that (for me, anyway), the Colbalts are not a better solution.

 

Very interesting. never been able to make my cobalts fade, ever (in street or race car).

No harm in using what you like and the carbotech is definitely a good product too.

 

[quote name='krazik' date='Dec 24 2008, 04:11 PM'] Very interesting.

 

I'm with you. I have never experienced fade with the XR3's on my car (with spec b's i would get some fade on the last few laps usually).

I used XR3's on my Honda Challenge car this year, 9 weekend (18 races) and only used one set of pads and rotors! I love these pads.

 

Had the same problem with XR2 and XR5 combo.

Carbotech xp10 and 8 user now.
