Alfa Calipers Options

[rgalla9146]

What Alfa Romeo alloy caliper (from what model car) is suitable to replace 3"
front calipers ?
AND...is it suitable for use on the rear of a 914 with 911 vented rotors ? provided
911 emergency brakes are adapted.
TIA

Hey Luke
I have S alloy calipers on the front and 914 6 rear calipers (widened 10mm for
vented 911 rotors) on the rear.
With the 6 rear calipers the ebrake cables rub against the exhaust.
This is especially true with headers.
To remedy this I'm going to install 911 ebrakes... I need to find suitable rear calipers.
I do have a full set of 944 turbo calipers and a 23mm MB master.
How did the 944 Turbo calipers mount to the 3 1/2" struts ... and can they mount to the 914 trailing arms ?
As you probably know I'm running 16" Fuchs so no clearance issues.

@rgalla9146 What can I do to help you brother, pictures of the bottom of my 6 and a
picture of the vented rear 914-6 caliper. My cables do not touch the Heat Exchangers. I did have eric set up a rear trailing arm with tube reinforcements and Elephant bushing for my V8 car that we changed direction on That was going to use Boxster non S rear with Rich Johnston adapters and vented disks

Hey Bob
Tell me about the Boxter rears and the Rick Johnson adapters.
Do you know the diameter of the Boxter pistons ?
I can't clearly see path of the ebrake cables in you pics.
In my car the cables will be melted by either HE's or headers unless I torture the
the path away from the trailing arm bracket
I have S alloys (48mm)in the front.
I need ~38mm calipers for the rear.
This nearly follows the original ratio front to rear.
The 911 ebrake install is to remedy the cable issue.
What is the finish on your HE's ?
Your car is beautiful.

Just some info from the web. The real answer is going to come from Eric or Larry at PMB but they are going to be super busy with Rensport.
I believe that @Sir Andy has Boxster’s all around on his Red 6. My muffler is polished SS custom 2 in 2 out and the Heat Exchangers have bright Ceramic finish.

I plan to run the standard Boxster calipers all around my car. The car will see street, autox, & some track time so I wanted more braking power. I got some of my parts from Rich (a914guy) check his ad in the members vendor section. I haven't installed the brake setup and have no answer on how they work. The all mighty Sir Andy also has the same Boxster setup on his 3.6 powered 914. He may be a good person to ask on how they work. Yes, you lose the e-brake but I installed a 911 e-brake setup on my 914 control arms. It's not a 5 minute job but it can be done. If I don't like the Boxster setup, I have a backup set of early 911 aluminum S & 914-6 rear calipers to try out.

-----Just general notes from web: Not me---
Gen2 Cayman & Cayman S Brake Sizes
Gen2 Cayman-
Front: rotor dia 298 mm, thickness 24 mm, piston dias 40 & 36 mm
Rear: rotor dia 299 mm, thickness 20 mm, piston dias 30 & 28 mm.

Gen2 Cayman S-
Front: rotor dia 318 mm, thickness 28 mm, piston dias 40 & 36 mm
Rear: rotor dia 299 mm, thickness 24 mm, piston dias 30 & 28 mm.

Non'S':
F Disc 298mm, Pistons in Calipers 2x40,2x36 mm , pad area 216 cm^2
R Disc 292mm, Pistons in Calipers 2x30,2x28 mm , pad area 196 cm^2

"S":
F Disc 319mm, Pistons in Calipers 2x40,2x36 mm, pad area 254 cm^2
R Disc 299mm, Pistons in Calipers 2x30,2x28 mm, pad area 196 cm^2

When I put 16" wheels on my 99, I couldn't believe how close the clearance was to the base brakes, so the bigger S calipers would definitely not fit with the OEM 16" wheels.. Not Bob B
