the aluminum adapters are rock solid. Well over 15 hours of track time and wheel to wheel racing, and enough heat to craze 13" rotors, but adapters are still flawless. Don't even have brake ducts yet (probably should do that..)

I need to make one small change to the design to make sure you don't have to modify knuckles (had to grind a ridge off mine) but I do want to have a run of them made. I wonder how many people would be interested? My kit would also come with hubcentric spacers. The rest are just nuts and bolts and the cobra stuff, easy for anyone to source and i'd provide part numbers, etc for all that. Maybe DB could stock them for me? Avoid shipping charges to MN.

Super busy prepping for another race this weekend at Gingerman in MI. They'll get further testing there, and i've got heat paint on them to really get a good feel of the range they reach.

Doing road race prep on this car has only expanded my list of DSM road race upgrade parts I really would love to see made and available to the masses.. Is there even a market for this stuff? I want to make a lightweight active toe eliminator kit, and a few other things.

So, turns out you can even clear GSX 17s! (needed a 1/8" spacer, not a huge deal)

OEM 17's are pretty narrow, so they should fit with almost any other wheel.

FYI - just followed up on a local machining lead, and I should be good to go once i get him the models.

Sorry guys, we decided to do one more race so this is yet again on hold. For sure after mid october i'll be back on this :D

Okay, I'm back on this. I'm actually ordering a 3d printer today so i can really refine and iterate on the design. I'm actually going to attempt to integrate brake duct mounts/adapters as well, as this is something we need on our car.

I also need to make a few clearance tweaks and ended up having to modify my knuckle to make the other ones fit. I don't want other people to have to do that.

More news soon, hopefully at least a few will be interested. i also will be printing my own rotorcentric adapters. I bought some off the shelf (ABS) ones and they actually did okay with the heat from racing at a track with really really heavy braking zones (Road America) so i'm fine enough continuing to use them. I'll print them in ABS.

Should end up being a pretty sweet and affordable kit. I have a CNC lined up for the work, as well.

I'm working on another part for the car which I've never seen before, not 100% sure it'll work out (won't know until I really get deep into the design) but it might appeal a lot to hardcore road race people. Most people probably won't give a crap though.

Though I don't have a dsm any longer, I'm really glad people like you are still doing part development for the community. Keep it up!

You know I'm in for a set.

Steve, if you want some to try out before that happens, I can send you my extra set of prototypes. You might have to fight Goodhart for them, but I wouldnt' mind getting someone else to try them out.

Not sure who would try them out first :D

I can bolt them up, but I'll be storing the car the minute the snow flies. Of course, that just might be in December.
