Ok guys it looks like there's a little more to the G30/M5 retrofit than an adapter ring.
I wrote Tro-Nik yesterday and asked if we could buy the ring from him and also what its size is.
This is what he wrote back:
You need a washer to install caliper
And need to cut the pads by the internal radius. So you need cnc
We have 2 kit
- 2 washers
- 2 adapters
- all bolts
And second
- first kit
- modified pads
I'm not sure what cutting the pads means but I don't like that we can't just buy off the shelf pads. I asked for more information along with prices.
