Can y’all make a new thread in the driving dynamics group? I feel there’s good info here that could be useful to the forum that’s buried in the for sale thread. Just a suggestion. Also if your install goes well I might want to upgrade too.Emailed the group.
No prob. Just trying to get more exposure without digging too deep in other threadsLooks like the mod split it. Thanks for that. I was going to eventually make a different thread.
This design uses our existing D1-147 ring (370x34mm ring that is widely used on Corvette, Camaro, etc. applications). This means the caliper can use a standard D1405 brake pad – we have street and race pads available in this shape, and it is commonly available across almost all brands as well. These replacement rings are a stocked item that we carry on a regular basis, so there is no worry of being stranded without rings down the road.
Final price is $1200/pair for assemblies (center hat + rings). We priced it to match the A1-147 Corvette part number, which feels fair given it is essentially the same amount of material and machine time. The bonus would be no extra charge for the R&D for customizing it to the Model 3 application.
The hat’s thickness is the same as our Model 3 Performance part number – meaning, it eliminates the stepped hub issue, and it appears that the same part number can be put on both Model 3 and Model 3 Performance hubs.
Have you sourced the dowels for caliper to spindle reduction yet? I don't think the term "timesert" is the correct term for this piece but I may be wrong. I most likely will purchase after seeing this installed.For those that are interested, R&D has been completed and rotors are ready to go into production with a completion timeframe of 3-4 weeks. If anyone still wants to hop in this buy, please message me and I will provide the link to purchase.
Here's some info on the rotors.

We don’t plan to stock this item, but we can make it in batches of 5 if enough people express interest in the future.
@TwoK4drSi 5 of us paid already, so Girodisc is ready to make this run. Like Jesse said, if you plan on getting these at some point do it now. Otherwise, you'll need find at least 4 additional buyers to get Girodisc to make another batch of 5+@TwoK4drSi - if this is a mod you plan on doing, I would jump in on the group buy with us. Otherwise you would need 5 people for Girodisc to produce the rotors for you at a later date, due to the cost of production.
What sequence did you go through to get them to bore cleanly?@TwoK4drSi while a timesert is doable, it’s a pain in the butt to find the correct sert to use. One of my calipers have been modified this way, but when I get it back I’m going to remove it and bore out mounting holes on the knuckles.
The best method is what @drpheta posted above. Also keep in mind, knuckles are pretty cheap to come by as well. I paid 65 bucks ea shipped from eBay.
I used a stepped drill bit and then finished with a straight 9/16 bit.
ah. Ok then I misunderstood. I thought the initial batch was 5 and then afterwards it could be purchased afterwards directly from girodisc since they already did the CAD work. Oh wells no biggie.@TwoK4drSi 5 of us paid already, so Girodisc is ready to make this run. Like Jesse said, if you plan on getting these at some point do it now.
