Does anyone known of a bolt on rotor around 330mm that will work with '86 hubs and spindles?
I came across some cayenne 17z calipers for cheap and want to come up with something hopefully cost efficient.
I've seen 993 c4s and TT rotor adapters but they're 250+ in addition to 400+ for the discs.
There's converting to late offset spindles and hubs with cayenne rotors...but that's around the same price, maybe a little cheaper. On the plus side of this, I wouldn't have to run spacers for high offset (more abundant) wheels in the front, then convert the rear later.
Thanks man...I'm going 87+ spindles and hubs I guess. Since I'm early steel arms, will I need camber plates to correct the camber? Will then eccentric bolt be enough for street use?
do you remember the camber on my 951 back when it was running on factory wheels and before I got coilovers and rebuilt the front end? That car was running the opposite; late control arms with early spindles and hubs and I had ~4° of negative camber with the eccentrics cranked as far positive as I could get them. I think you'll need camber plates.
Looks like a lot of unsprung weight to add to your car. Are you pushing 500whp to warrant these?
They're lighter than they look. Cross drilled and slotted cayenne rotors are just a little heavier than stocks too. My wheels are only 17 lbs each also so I have a little bit of weight savings.

Are camber plates a better solution than factory late offset control arms? Seems like a bandaid.
Kind of hard to justify due to having brand new early arms, bushings, and ball joints. If it sets at desired camber with no negative effects, I don't see what's wrong with it. I did some reading and some track guys have done it for brake purposes with no ill side effects.
When through all of this a few years ago with my 86' 951 and found out even with adj. camber plates and early offset control arms I couldn't get my desired settings. Late offset control arms are not that much and you'll also have to buy the late offset tie rods for swap out on your steering rack. All this was done so I could run 330mm Cayenne rotors with 996T mono block cal. Good luck as it's hard sometimes to go half way or make compromises with these cars.

Agreed....thanks for the insight. Some things I've found solutions for and was hoping I'm there's one for this but it doesn't look like it.
How much camber were you running with plates and eccentrics maxxed out?
