hi folks,

Washing the car after a serious track day on the wonderful Spa Francorchamps F1 track in Belgium, I realized that my front spoon brake discs (rotors)had started to crack (small cracks around the holes drilled through the discs)
New panther + pads Saturday and 200 miles of hard track driving Sunday (with 3 major braking zones per lap at Spa) but I do have a brake duct / cooling setup sourced through S2Ki

This is the second time I

 

All brake rotors are going to develop cracks under the stress of tracking the car. If I were you, I would keep the fancy Spoon/Powerslot/whatever rotors for the street and just use plain old OEM-type rotors for the track. Rotors are like pads -- they are wear items.

Well OK, if I really were you I would have never bought one set of Spoon rotors in the first place, much less a second set.

(I just swapped out a pair of rotors at my last track day. I had a braking vibration that was just getting worse and worse. My rotors were cracked, but not enough to be structurally significant. I had driven on them like that for several track events. But when I swapped out the rotors the brakes just felt so much better....)

 

Just get blanks, less cracking.

 

I agree. Bling-bling isn't for the track.

But hey, they're JDM they must be the shiznit, roight?

 

thanks for the replies,
in reason I got them in the first place was hoping to improve braking and reduce rotor wear relative to the standard rotors that wear down fast with aggressive pads

I also get the impression that spoon is one of the least bling of the japanese outfits (for ex. the plane-jane black "only" 16' wheels (made in Russia!) that also happen to be amongst the lightest ...

oh well .....

 

If you want serious race track brake setup go for AP racing!

 

Whats actually the size of the spoon rotors?!

 

I think they are OEM size. Bad news euros2k The lightest disc as far as I know is the Project mu.

 

Brake rotors are one of the least cost-effective places to save weight. And as for durability -- if a rotor costs three times as much as a plain OEM-style blank, it has to last for three times as long to make up the cost. Not too likely.

 

Although this is a very true statement, as far as I'm concerned only a product of questionable quality is going to crack in just 200 miles, regardless of how demanding the track is.


euroS2K, I'm getting about ~900 track miles on my OEM rotors plus the ~10,000 street miles per year, and when I replace them in the spring they only have the tiny little check marks, not real cracks.
