Big Brakes

Friends,
Have anyone ever installed big brakes on an alfa 33, with 15 inch rims???
Thanks

Hi
have a look over there:

Alfa Pages :: Index

Am sure i have read thread on brakes there.

But just remember to come back here too

Hello 33alfa, yep I have fitted 300mm rotors and 4 pot calipers to my car a little while ago, only i have 16inch on the car and for them to fit under 15inch might be a bit tight, the brakes are from Hi Spec in Dartford , they also have a web site, the guys there are helpful modifying a bracket so the calipers fit to the hub , but they do cost quite a bit of money, but a lot less than than apart or brembo.

thanks mate i will contact them and give yoy the feed back

thanks for the help. i think alfa 33 has 239mm rotors u went to a smaller diameter

A simple solution might be to move the standard 33 calipers further out to take a 284mm disc. It should be possible to fit a 284x22mm disc from Alfa 155,145 etc

4 pot calipers are expensive and also much bigger than the standard type calipers and hence difficult to get under a 15" wheel

Pads are too small for efficient braking in that case.

For 15 inch wheels the easiest solution is Alfa discs 284x22 and Vauhall Calibra calipers:

Discs:
ALFA ROMEO 155 2.0i Turbo 16V Q4 92-97
ALFA ROMEO 155 2.5i V6 92-97
ALFA ROMEO 155 Turbodiesel 2.5 93-97
FIAT Bravo 2.0i 20V HGT (155) 95-00
FIAT Coupé 2.0i 16V Turbo 94-96
FIAT Croma 2.0i Turbo 93-96
FIAT Croma 2.5i V6 93-96
FIAT Marea / Weekend 2.0i 20V (155) 96->
FIAT Marea / Weekend Turbodiesel 2.4 (125) 96-99

LANCIA Delta HF Turbo Integrale 8V/16V 11.87-91
LANCIA Delta HF (II) 2.0i.e.Turbo 16V / HPE 5.93-99
LANCIA Lybra / S.W. 1.8i 16V 99->

LANCIA Thema 2.0i.e.Turbo 16V / S.W. 10.88-94
LANCIA Thema 3.0i.e.V6 / S.W. 91-94

Calipers for 284 disc:
OPEL Calibra 2.0i 16V Turbo 4x4 92-95 284 disc
OPEL Calibra 2.5i V6 24V 93-95 284 disc
OPEL Vectra 2.0i 16V Turbo 4x4 9.92-9.95 284 disc
OPEL Vectra 2.5i V6 93-9.95 284 disc
SAAB 900 (II) all models 9.93-8.96 284 disc
VAUXHALL Calibra 2.0i 16V Turbo 4x4 92-96 284 disc
VAUXHALL Calibra 2.5i V6 24V 93-97 284 disc
VAUXHALL Cavalier C 2.0i 16V Turbo 4x4 9.92-95 284 disc

Only brake lines have to be custom made.

BTW pads are the same as in all Alfa models with 284 discs (Alfa 147 20, 156 2.0....) so we are safe, there are no forbidden Vauhall/Opel parts on Alfas (calipers are Ate)

You will be limited to the 284mm disc with a 15" wheel. I run a 315mm disc but that requires a 16" wheel.
You should be able to achieve more than satisfactory braking with a 284mm disc on a Sprint - the 315mm and 4-pot calipers i run are a bit over the top for a road car.

Was going to say the same thing but you just need to watch the Vauxhall calipers are designed for 24mm wide discs but shouldnt be a problem unless you ran the pads completely flat

Now I just need to find some calipers that will fit the 305x28mm or 330x32mm Alfa discs for my 156 without having to fit 4 pot calipers

I am running 256 discs, and they are enough for 7-8 rounds on the race track, so 284 are more than enough. Sprint with 315 is Sci-fi

Why? fit Alga GTA calipers, just have to find that GTA part where disc and calipers fit (don't know english word for that part which is different on GTA model)

Already have 4 pot Brembo's on one car and looking for something cheaper that will fit 16" wheels for my other car but still give increased braking. Alfa parts are hard to find here too but I will probably just fit a set of Ferodo pads instead
