The Racing Beast :: 1988 Alfa Romeo 75 3,0 V6 Group A

[Steve Webb]

it´s like a hydraulic handbrake just to fix the car.
The second valve I need to adjust the rear brake power.

That makes sense, i did wonder why you'd have a line lock on the rear brakes on a rwd car but using it as a handbrake makes it all clear now.

Do you find yourself adjusting the brake bias much? I did think about a bias valve for the GTV, especially as I will be upgrading the front brakes at some point.
Rear brakes will stay standard given the cost of RZ/SZ rear disks!

Hi Wolfgang. Awesome 75!

What brake kit are you using in the front?

[Wolfgang]

Ciao ROCisIN !

Sorry for my late answer, but I was really busy the last months especialy with upgrading my race car, ... saison opening will be on the 13th of April.

I have used the RSR Kit in front with 305mm upgrated discs of the 147/156 GTA first serie with spacer kit and mounting brakets.

But during this winter I made another mounting braket for my big ALCON 4 piston calipers which I had left from my privious race car and so the old RSR upgrade kit for the original 75 brembo aluminium 2 pot calipers is now on stock. Diameter of the discs is still 305 mm because of the BBS 16" Magnesium rims, brake pad area is almost doubble size as the one from the original 75 brembo aluminium 2 pot calipers.

On the rear brakes I also have done an upgrade to the vented discs like the SZ and RZ.


Many many greetings from Austria

Hello Cristian !

Nice to hear from you also, how are you, ... yes I did a lot of work on the race car during winter time but also I had a very big project running through the winter, ... I made a complete technical overhaul on a 156 GTA of a friend of mine, ... he had invested arround € 8.500 in this car, ... almost everything technical new starting with gearbox incl. Q2 diff, clutch, both clutch hydraulic cylinders, timing belt with all bearings, sealing rings, camshaft, hydraulic lifters, complete suspension new headers, complete stainless exhaust with cup pipe in the middle and so on and so on, ... electrical problem with 0,75 A power loss during parking (but I´ve found almost everything !).

One bad new or let´s say better for my free time and family time, ... I´ve stopped my 155 Q4 project and have sold everything, really every screw of the 155, I have made a special deal with a friend of mine where I got the 75 race car, ... he gave me a lot of spare parts like engines, gearboxes, 1 Alfa 75 3,0V6 America technical O.L. but very very much corrosion (just for disassembling) and 1 Alfa 75 3,0 V6 QV with a little front accident (for me also only interesting for disassembling). So I will have enough spares for my race car. And I cannot stop everything so I will build up a new really "sharp" race 3,0 V6 12V engine with hopefully arround 300 Hourse Power or more.

That´s enough to play with, ... every other work be to get money and not to pay in money.

Many greetings to all of you Cristian and of course also for you
Wolfgang

Hello, Wolfgang!

I have thought about being pretty complicated keeping both projects. I've wondered from the beginning how in the name of God the 75 found it's room there. So even I feel little sad for that white 155 Q4, I am not surprised. Must have been a hard decision for you. I wish you good luck racing the beast and with everything involved.

Btw, I have the same electrical problem with my Q4 eating power during parking time so I will have to take it step by step with that soon...

Good to see you're keeping up as usual.

Many greatings from us to you my friend and to your beloved family.

Cris.
