Thats it B. I got some more pics of it including bodywork on one of my discs. Trying to find. I see a lot of the pics Andrew took are slowly appearing as featured cars in Auto Italia including Dougies car with the old big bore carb motor in. (They should now test it with Dawies new big bore 24v and your brake modifications)
Well found a picture of this dual calipper stuff.
And back to the rear swaybar size. For my GTV i have a new rear swaybar from performatek 25.4mm and its adjustable.
Well abut the size. When i was down in germany driving on the Nordschleife/Nurburgring with those Alfa 75 Experience cars of Ron, we decided to take of the rear swaybar becasue of the crappy weather that day. It proved to be very good to drive on that track. One bacause it was wet as hell, and two because that track ain't straigth bumps and stuff. So the rear end of the car was more forgiving than it normaly is. And it was really cool when on the last round i was driving it started to snow!
Ultimate drift car? 
So the rear bar that i now got for my car is adjustable i can set it to soft on a wet day or a bad bumpy track or hard for a clean straight track on a sunny warm day

That brake setup was brilliant for its day!! Dont slam it!!
We did a full 9 hour endurance at Kyalami on that brake setup and it lasted extremely well...
It was done by Brembo for Autodelta..the proper one.

French cars are shit and shit expensive to service and bloody awful and unreliable and expensive and friends don't let friends drive french cars and you wait years for parts.
On a track, couldn't you get better lap times by having slightly softer spring rates, and using a sway bar to pick up in the roll stiffness? I know brake dive is negatively effected, but over bumps you might have an upper hand over an overly stiff setup?Micke wrote:Let's invert the question:
Why should it be bigger?
And Micke, I'm simply trying to learn.
@U5,
Any reason you dind't go with Ron's 4 position adjustable rear bar?
I was originally going to buy Andy's bar (as I'm in the US) but with my 75, I'd have to buy his sway bar end links as well, and at that point the bar was nearly as much as Ron's, all the way from europe.
BMW's are the ultimate driving machine!
I'm kidding -- please don't ban me.

Learning is OK. That's what I'm trying to do all the time as well. Asking questions and creating discussion is the best way.
The need for a really stiff AR bar is mainly on a street driven car. Race cars need bloody stiff springs anyway to keep the nose off ground. To get the roll down to acceptable for track mainly with springs would create a horrible stiff ride for the street. Hence the stiff AR bar instead.
I'm sure there is a scientific ratio how much roll stiffness should be created by the AR bar vs. springs but I don't know it. Probably there's quite a lot of room to play with.
The importance of AR bar comes in fine tuning the suspension as it is much easier to correct balance with adjusting the bar than swapping springs. That's also why a good AR bar should be adjustable.
