·my ap evo 7 kt is on it s way
so in my waiting period i tested some more i have no on my car godspeed 2 piece discs. this is how it went today
new hubs
put the discs on the car with standard wheels major vibration even when cold
the 2 piece discs has a thicker bell and does not leave enough space on the hub to centrate the the standard wheel
so changed the wheels which has more metal left on the centre inside. the cold vibration was gone
i was using ferodo 4003 full face pads this setup works great but after a few times hard braking the discs get hot and leaving hot spots on the disc (judder)
ok change the pads to ferodo 2000 pads small pads 1.5 cm smaller guess what no problems anymore the discs are blue in colour 5 high speed stops from 220 km to 50 km
but my big test comes on sunday when i go to the track again
so i called the braking company and ask what happend why does a smaller pad work ok and a full face pads leaves spots
this is his opinion
because of the larger pad the caliper can not push equal forces over the full face of the pad and then you get differant temps on the disc surface which can cause vibration
this works only on new discs so don t try small pads on already warped (reskimmed) discs it does not workt i have tried that.
be aware that the standard brembo discs are not a high quality disc
but maybe a smaller pad on a new brembo discs will work who knows maybe here is someone who tested it i love to hear youre thoughts about it
