993 Turbo Front Disks

[aircool]

I currently have 944s2 callipers and 944disks fitted to the front of my half built beetle but when I came to fit the wheels (18") you could hardly see the brakes! So I managed to get some 993 turbo brake disks cheap on eBay (which look wicked behind the 18's:cool: ) but my s2 callipers won’t quite fit over them.

So do I have to get 993 turbo callipers or are there other Porsche models that will fit? The other alternative would be to file the small up stands that stop the calliper from sliding on but I'm not sure if it would still be tight or even safe!:confused:

are they not pinned in?
-will they actally fit?

[aircool]

Pinned in where? are you talking about the pad? and I think they would fit with filing but I'm not entirely sure, not taken proper measurement's yet.

Don't waste your time with the 944S2 calipers. They are designed for a 28mm thick disk and the 993T rotors are 32mm thick.

If you somehow file the S2 calipers to fit, you will only be contacting the 993T rotor with the S2 pads on maybe 3/4 of the rotor area. Why ?

Get the proper 993T calipers $$$$

well, any hoots the bother you will have is
-a 993 has a hat size of 72mm
-a 944 is 75

-so you are 3mm short for starters
-plus, the 993 disc is 305
-the other 299
-so there 3mm that may toch the caliper there

Well the hats are being custom machined like in Sandeep’s article and the bigger diameter is easily overcome with a spacer for the calliper. But sandeep has a good point about the contact area. I think I will get bigger callipers. Does anybody know if the boxter S ones would be up to the job?

Also Sandeep, could you possibly supply me with the dimensions or drawings for your custom hats? It just gives me something to cross reference my cad drawings with.

dou you do
3.5 inch 89mm
-to radial adaptors?

[aircool]

I've designed some adapters for the 944 s2 callipers to run with the 322mm disks, it just offsets the bolt holes. If I get radial callipers I'll buy adapters as its easier.:sleep:

Pantswagen, I looked at your link and notice you say 996 Callipers will work with these disks are you 100% sure?

[pantswagen]

nope

-all i know is after i have fitted a 944 turbo hub to a 71 bay spindle, by shortening the spindle, maybe i can use the 930 disc -305/32 -72mm hat
-but i bet i need the reach of the 964 299 by 28 -80mm hat
- tried 'what i had, a rear 996 299 by 28 -75hat -and it may work with an off the shelf adaptor for 911 's' to 996, as bay window 1971 spindles are the same as 911's' =3.5ich on centres

-996 fronts are for 32 i think
-bocster 986 are for 28 -
-they are i think the same distance from mounts to pads too - unsure

-i need a set of adaptors

-typeically, i need my van rolling quite soon
-and managed to get all the rear stuff, 944 turbo torsion, 85 hubs -996 discs and 996 calipers, and the adaptors, but stoopidly bought 2 right rears1

-still hope fully i will use the 2.7 boxsters with 299 28 964 discs
???

who knows>?


-i know my caliper boss to hub face is 95mm

-so -80 for the 964 disc, do the adaptors put the inner pad over 15mm -oh minus the hub face disc thickness -it all starts to get a bit messy!!!

did you see the prices on that site -cheeeeep -964 discs and the 993 -i might have to buy a pair
-but i need to first sort the spindles and bearings out, cut the spindles re-thread
buy the off the peg adaptors -fill the gap.
