well i came across this wheels that have a variable bolt pattern from 4x100 to 4x114. does anyone have any info on this? is there another company with such system?

brand: Heroes racing
model: Super Speed...i think
size:15x6.5
offset:20
pattern:4x100 to 4x114....

 

that is the only company i have seen that offers that type of system. the insert gives you a 100 pcd and without the insert you will have a perfecty seated conical seat hole for 114 pcd. seen these a couple years ago and once on my last trip to japan.i was thinking of purchasing them as well. good stuff.
