which one are better for auto x??

 

XP hands down.. for auto-x.
but you may want something that has even more initial bite. (without having to heat up)

I don't auto-x, but can tell you that the XP will be much better than the Blues. However, I'll also say that you'd be better off with a milder pad like the Panther + or Porterfield R4S.

Hawk Blues take much longer to warm up to optimal temperature than the other pads above. The + and r4s would be the best choice for street/auto-x IMO.

 

thanks guys for the info

 

Those are both overkill for autox, not to mention the Hawk blue will eat your rotors due to the lack of heat. Blues need a attain a certain temperature range to work effectively and unless you autox runs are 30 mins long you can not do it.

If you want a good autox pad look into Hawk HP+, Axxiss Ultimates (have these, love them) or Porterfield R4S.

 

neither...
Stock pads will work better due to a better (lower) working temperature range.

Carbotech Kelated Green pads

(Taken from Carbotech's website)
"CARBOTECH KELATED METALLIC GREEN 913
A D.O.T.-approved high-performance compound, Carbotech Kelated Metallic (CKM) achieves a very high coefficient of friction (approx. 0.48 to 0.50) by taking advantage of a chemical reaction within the friction mass, which creates a tri-alloy metallic film at the liner/drum interface when subjected to heat and pressure. Designed to overcome the shortcomings of other liner materials, CKM is very versatile and provides excellent braking performance in a wide variety of applications. Excellent wear characteristics and a very high resistance to lock-up under hard braking. Optimal recommended operating temperature range is from ambient to 750F."

Boy do they have cold bite! Something to look into. But, the Axxis Ultimate is cheaper and should be a very good pad.

Dont use either of those pads for autocross. Not only will they chew your rotors up, but they wont heat up sufficiently for autocrossing. I used both AEM's and Porterfield R4S's, and both worked just fine for autocross.
