Broken front hubs?
 

I just turned down my front hubs to allow the use of the 993 front rotor and now I'm reading where I shouldn't have done this. Did a search for broken and/or cracked hubs and found no pictures or threads even. Where do they break and is .120 off the od going to really matter? I thought this was a great idea to use the 993 rotor and caliper as a package and keep things simple. Also is there a clearance problem with this on the strut mount area? Seems the caliper is awfully close to hitting the mounts on the strut. Is this right? Thanx, Duke

Bill V, Do you have any comments?

I dunno, never did that myself

I do know that the 911 hubs are none too strong. Looks like you might be a test mule for this.

I like the 2 piece rotors because they are lighter and handle heat better than one piece rotors of the same size

Duke,
I'm getting ready to do a 993 caliper up grade on my 75 911,for cost reasons I was considering turning the hub down like you did and using 993 front rotors.

Have you made any further progress with your upgrade ?

How did the 993 front rotors end up working out ?

Any and all comments will be appreciated.

Gary, I haven't finished this yet. We are working on the adapters and I'm still working on my tub, may be a month or two til I'm ready to mount everything. I'll keep you posted.

Hi Duke,

Does it look like the "standard" adapter that a few different places sell for the 993 calipers will work with the 993 rotors ?

Or is the placement different and custom adapters need to be made ?

Gary, I guess I can't answer your question right now. The boys atr the shop are working on the adapters for me. When they are finished I'll compare mine to the specs on here. I think Bill V. posted them somewhere.

I'm getting anxious to get started and I want to buy the right parts the first time, I either have or know what to get except for the front rotors.

I sure wish I could justify the additional cost for the factory 78-80 front floaters...
