I'm new and I'm looking around for a 968 and was wondering if there were different size brake calipers offered on the 968. I'm thinking there wasn't, but thought I'd check here.



Also, what type of LSD is in the 968 with the LSD option? Torsen?



And last, how did the sister car, the 944 S2, compare with brake size and did it have optional caliper sizes? Did it have a LSD option?



Thanks for the patience.

all standard model 968s had the same size calipers year to year - M030 cars had different front calipers



there were 2 types of lsd in the 968 - clutch and torsen - earlier cars had clutch type available, later replaced by the torsen



no clue on the predecessor

Re: the 944S2's: I believe they had the same stock brake calipers as the non M030 968's. I know that you could order the "220" LSD Option for a 944S2 Coupe; clutch type IIRC. I think I had it on my 944S2 Cab as well; memory is fuzzy after all these years/

sounds right to me

If you bought a non m030 car I suppose it isn't a simple caliper upgrade to get the larger calipers, correct? Seems I recall reading about specific uprights and mounting brackets, some of which may be NLA.



I do appreciate the info.

here's a breakdown of all the M030 stuff, but you can scroll down to the brakes:

A non-M030 car requires adapters to mount the M030 front calipers. I bought mine from Racers Edge (www.racersedge-inc.com). Requires M030 brake disks, but otherwise quite simple.



Note that the 944 Turbo S brake disks (which fit) are solid (non-drilled) and MUCH less expensive than the drilled 968 units.



Adapters convert from axial mount to radial mount or visa versa...

by the way ron, the stock brakes are fantastic. If you are needing more brake power you are doing really heavy track use.



IIRC, we are limited by the tire contact patch size more than caliper/disc size.

Intended use is a pure race car. I've been looking at the stock brakes and they are better than anything we've ever had on any of our other race cars, and we get those to work fine with ducting and heat sinks, as well as proper pad compound selection. I'm inclined to try the stock brakes first because they look pretty nice I agree.

I'm finishing up a 944 track car and went through the brake decision recently. The 968 brakes were the same as those from the 944 Turbo (non S) from 1987 to 1988. The 1986 Turbo brakes look the same (probably no performance difference, but there is a slight difference in one of the piston sizes (of the pair for each caliper). The 944S2 used the same as the non-S Turbo and the 968. You will need to change the spindles for a NA 944. ABS vs Non-ABS changes the conversation a little as well. I went with 1987 Turbo spindles, caliper, hubs, rotors, and ceramic pads. I did not drill the rotors.

Ron I had a 1989 944S2 with M030 sport suspension and brakes and LSD prior to getting the 1993 968. The LSD is the clutch type which can be an advantage in a race car since you can adjust the clutch discs to provide more lockup than the TORSEN provides (only 40% with no adjustment). A car with non-M030 brakes can be converted using adapters for the calipers as stated (I bought mine for the 968 from Paragon Products) and the larger calipers can be sourced from a salvage yard (1987 and newer 928S4 are the same) for less than buying new ones. Drilled or nondrilled rotors are your choice (I do not like drilled rotors) and available from numerous parts places. Since owning the 968 as well as the 944S2 I think if I were building a track only car I would start with the 944S2 and save quite a bit of money to start off with. Good luck, Bob Blackwell.

It's my understanding that 968's in 1992 with the "220" LSD option came with Clutch type, in early 1993 they COULD have either Clutch OR Torsen, in mid 1993-1995 TORSEN was standard.

I know I've read this before somewhere, but this would be useful information for him.



How much would he be looking at to add LSD if he bought a 968 without?
