It's a nice setup, w/ a possible issue.

The issue revolves about which caliper the rear is
there are 2 possibilities
1)tt w/ 28/28 pistons
or
2) RS w/ 30/36 pistons

the tt setup will be heavily front biased, this was a safety factor when used on an AWD, ABS equipped car

I have the RS set on both my cars and it's fantastic

Most people haven't a clue as to which is which, see if you can get the rear piston sizes from the seller, they will be printed on the spyders if they are still used or at least see if they are different sizes(this will be very obvious)

Hello Bill my name is Rich first let me say I have greatly enjoyed reading your posts on brakes and their balance. I have an 81 sc widebody with a 3.0 930 motor. I was wondering what you thought about this setup. Porsche 911 930 911TT Brake Conversion Kit with Adapters Calipers Rotors Pads | eBay

Those are 911 8 x15 Et10.6, they were oe for on the back of a 911SC or Carrera. I they are used on an ST fendered car you will need spacers in back, they should be fine in front
ST

STs used 8ET10.6 front and 9ET3 rear

Hi Bill, i have contacted you before as you clearly know your Porsche. I am building an st replica using an sc shell as my donor. Completion is still a long way off but I am already considering suitable wheels and off sets etc. I've seen a pair of 15x8s on eBay, they are original fuchs but images of the wheels show them fitted to a 944. I wondered whether they would be suitable for the front on my car. I want to achieve a race style stance and want to fill the arches without causing any interruption or rubbing. The wheel size and off set advertised is Porsche part 911 361 020 42. 5 stud pcd 130mm / et 10.6mm / centre bore 71.5. Really would appreciate your opinion before I start bidding. Regards sean

The bias on an '84 can be changed to that of an earlier car(SC) by changing the rear caliper/rotors to those used on an SC, when this is done the p/v needs to be removed

I always use M1 15w/50 or Brad Penn 20w/50

Hi bill new owner to a sweet 1986 911 oil question brad penn vs shell rotella -t 2 shops around us (i live in loudonville too) say either is good your opinion ? please let me know thanks much Jeff schneider

Hi Bill,
I know you are the forum Brake guru, so had a few questions...

1) I have an 84 Carrera Stock brakes.. stock MC. Is there anyway to make adjustments on the bias? or PV?
2) Can I put Carrera calipers and rotors on an 82 SC ? I have one of those too.. and looking to do some upgrades..

thanks for the help

Good morning Bill,
I recently had an experience with a WUR and was hoping to post a PDF summary of the
event to the thread. I have reviewed the site information and get the impression I might be
able to add an "Attachment" to my thread. I am not able to do so, beyond photo. Is there
some sort of limit to the use of attachments here? Thank you, Paul Miller

Hey Mike, Funnu you should ask, my car has spent ~5mo at Automobile Associates of Canton for one project or another. They are located in Canton Ct. and do wonderful work, I can't say enough about how good they are.
