964 C2 With 965 Suspension??
Hi All,
I'm about to start a major spend on my much loved 964 C2 Coupe manual starting with a full engine rebuild to 3.8 litres with Motec and PMO's (more on this soon) but I'm trying to save a few shekels when upgrading brakes and suspension, if possible.
Does anyone know if it's possible to fit the Turbo suspension set-up (coil-overs) to a 964 C2 (with 18" wheels) please?
The plan is to fit the 965 "Big Reds" and new Turbo rotors, but I was wondering if I can also make use of a stock 965 suspension (only 13,000 miles on them) and if so what else would I need? Hubs etc??
Pardon my ignorance and thanks in advance.

If you limit yourself to the shocks then yes, f/r 964t shocks can be used on a 964
If you want to use the 964t trailing arms then no, they cause the rear wheels to be more offset to the outside, on a race car they would usually be exchanged for regular n/b versions, or n/b versions with stiffer bearings.
To use 964t 322mm front brakes you need the rotors, calipers and caliper adapters unless you swap in the 964t wheel carriers too, in which case you don't need the adapters. Another alternative is to use 993 or 993RS aluminum wheel carriers instead of the steel 964 versions. If you do that then you use 993tt/RS rotors and calipers. You cannot mix and match 964 brake pieces w/ 993 brake pieces here, with one exception, the 964T calipers can be used in lieu of the 993 calipers.
in back you will want to use 993 rear calipers which bolt up to the stock 964 trailing arms and use stock 964 rear rotors, or you can use 968 M030 rear rotors as was done on 964RS.
To use the above brakes you will also want to install a 993 brake booster and m/c and remove the stock p/v.

Hi Bill,
Thanks for your reply and for spelling it out in a way in which even I can understand.
So far I have the 965 front and rear stock Brembo callipers, and I was offered the shocks and springs at a price it was worthing taking a punt on. As they were little used I thought if it didn't work out I could perhaps sell them on again.
Much appreciated,
Paul

Hi,
I was thinking of fitting the matching Turbo rotors, is this possible?
Apart form the odd track outing the car will be used mainly for pleasure, touring and rallies.
Cheers,
Paul

Not on the narrower n/a trailing arms, for street use you don't need anything more than stock brakes, I also know lots of couples that share their 964s at track days and thus dual stint the cars, stock brakes seem to work fine for them.

The part nos. I have (from 1993 3.6t) are: 993.351.42(5)(6).10 & 965.352.42(1)(2).12
My understanding is (please correct me again if I've got it wrong) that:
For the front I can use the the 964t if I use caliper adapters and turbo rotors. Alos, any recomendations where I might source the adapters please?
For the rears, I should stick with the stock 964 rotors and use 993 or 968 M030 RS style calipers which both will bolt straight on.
The turbo shocks will also bolt straight on the 964 too?
You have been great, helping me tip-toe through a minefield
Cheers,
Paul

Not sure this is of any relevance to you, am in the throws of a brake upgrade, I bought a brand new (never fitted) set of 993 TT brakes (discs, callipers and pads, front and rears) for my C2 964, the fronts fitted fine (with adaptors) the rears did not, feeling dumb for not researching my purchase first, spoke to an expert who suggested fitting rear RS 964 discs to the rear (drilled so matches the fronts) and then the clever bit, fit my old front callipers (rebuilt, painted, etc) on the rear!, all seems to be fitting together nicely, cant wait to try them out

Velberg is correct here, this is TOO much rear brake (for 99% of us). I've argued with him ad naseum about this and now agree with him. I would not do this on a street car-although your single channel rear ABS may save you here.
For all but the most precise race applications, I highly recommend that this not be done...you would be wise to really get into your brakes to insure your rear end remains where you want it in an emergency.

The 964RS/t and 993TR/tt front rotor are both 322x32 drilled rotors, the 993 is a 2 piece hat/annulus design the 964 a 1 piece design, the 928GTS is a 1 piece plain design though I have seen slotted and dimpled versions I don't know where to get them.
correct

Again w/ the 993RS/tt fronts the best choice for most people is the 993 rear caliper on stock 964 rear rotors(you can use 968 M030 rear rotors which is what they used on 964RS)
here are some #s for you to think about, these are brake torques @70bar line pressure for several setups, followed by the ratio
911 SC 1444/969, 1.491
964 1974/1139, 1.734
964RS 2381/1390, 1.713 most owners remove the p/v for this setup
993RS 2306/1618, 1.426 the p/v can be removed though it rarely is
993RS front/964front 1.216
p/v modify the above when line pressure exceeds the knee for the p/v this limits rear torque
I don't like using fronts in back because the calipers are then used on a rotor that is smaller than it is designed for and there is a risk of hyper-extension when the pads get thin.

Yes those are red 964 3.6t front calipers, they were also used on 993tt/RS. You need 322x32front rotors. There are 2 different o/s rotors available, 1) is the 964RS/964t/928GTS style these have an o/s that works w/ the 964 wheel carriers, 2) 993RS/tt these have an o/s that works w/ 993 wheel carriers. You cannot use a 964 rotor w/ a 993 wheel carrier and vice versa. If you use the 964t or 993 wheel carriers then no caliper adapter is needed as these both have axial caliper mounts, if you use the regular 964 wheel carriers then you need a caliper adapter, VCI would be a good source.
The 964RS/t and 993TR/tt front rotor are both 322x32 drilled rotors, the 993 is a 2 piece hat/annulus design the 964 a 1 piece design, the 928GTS is a 1 piece plain design though I have seen slotted and dimpled versions I don't know where to get them.

you got that 1/2 right. Use either stock 964 rear rotors or 968 M030 rear rotors, the difference is that stock are plain and 968 M030 are drilled. W/ either of those rotors use either 964RS rear calipers(rare) or 993 rear calipers which are the same w/ a different part #.
