question on 944t brake conversion.

[alt+f4]

ok looking through some books that had 944 conversions and your site. tell me if i got this right. the disk mounts on the back side of the hubs....like Wheel/tire,Hub, disk?

thanks

I think early set-ups mount the disc on the back of the hub, late over the top.

thanks! deffinitly odd way to mount the disk....at least to me it seems odd.

There are 5 different 944 front rotors:
1) Early NA, 282x20.4mm, mounts on the back of the hub with 5 screws
2) Early T, 298x28mm, mounts on the back of the hub with 5 screws.
3) Late NA, 282x20.4mm, mounts on the front of the hub
4) Late T, 298x28mm, mounts on the front of the hub
5) Turbo S, 304x33mm, mounts on the fornt of the hub

There are 4 different rear rotors (all mounted to front of hub):
1)Early NA - 290x20.4mm
2) Early T - 86 only, 299x28mm
3) Late NA - 86+, 290x20.4mm, alum arms
4) Late T - 87+, 290x20.4mm, alum arms

(Early and late rear rotor differ by their pilot diameter, technically the late rotor will fit and early hub, but the pilot sizes don't match and you'll by radially positioning the rotor with only the retaining screws......)

Easy,

Thank you Flat! This info is very useful for me too. Are all types of rotors vented? (front and rear?)

yes. solid rotors are usually 9-11 mm

Thanks, now that I think I realise that too... Sorry for my dumb question...

[alt+f4]

thanks guys! Looks like i am going to start to search pick n pull for all the req parts. so i need to find a late Turbo for the fronts, and a Early NA for the rears. i am just going to keep the stock beetle arms.

Now i just need to find my self a 73-74 super in the next few months.

Ok i think i finally got a hang of this....don't know why it was so difficult. I am going to go with the Turbo S Fronts and Early NA Rears. I Chose this because i am going to be running a full cage that is tied into the suspension points, and also have a full interior. Now my only question is 16" or 17" rims....i will go 17" if i have to with the larger disk size of the Turbo S fronts.

I will also be investing in Lanners Super Duty Tie rods.


Now to sell a car so i can buy all this!!!


BTW You still make the billet hubs and do they come in Turbo S size/pattern?

[flat]

I'd advise against mixing NA and T parts. Keep your whole car with the T calipers/rotors. Better brake pedal feel and you can keep your stock MC.

And, if your pockets are deep enough I can make anything. (I mean 'yes')

[alt+f4]

i was going to go with a dual MC setup with a remote adj. balance bar.

with doing that would you still recomend sticking with T parts?

[flat]

From a strictly cosmetic point of view, keep it all NA or all T. Mixing and matching creates a 'frank-en-car'. With the dual masters you can make anything work.

i havnt seen either of the two types side by side and i can never recall what they look like.


I know i will want the larger rotors though because my car will end up heavy.

Turbo TIV
915 Trans
Full Cage
Mostyly full interior.

Turbo is 298x28F, 299x24R, with 4 piston Brembo aluminum calipers all around.

NA is 282x20.4F, 290x20.4R with sliding steel single piston calipers all around.

I'm working on using the NA setups with Wilwood calipers. It's the perfect marriage for light cars (Bugs) because you have a light rotor (low inertial, rotational mass and unsprung mass) with a light, efficient 4 piston caliper.

Most of the time, the Turbo setup is too big and heavy to justify. There are some exceptions though....
