I was about to order my master cylinder but was faced with two questions. I dont want to order the wrong part. Since the s4 GTU is pretty much an N/A in full turbo trim should I order the master cylinder for a turbo and I know the suspension is supposed to be "sports tuned" but they asked me if it is adjustable. I dont think it is because I dont have the adjustable middle console controls.

I was about to order one for a turbo, without adjustable suspension. Is this what I should order?

 

Order non-turbo, non-adjustable suspension. I replaced mine a couple of months ago in my '88 GTU as well.

 

And the 88 GTU does not have ABS right?

If so which one of these should I buy?

I think, though not 100% sure that the only difference between brake master cylinders between 5 and 4 lug was the fill tank size. The 5 lug brake booster is bigger then the 4 lug brake booster.

Can anyone else confirm this or tell me i am spreading lies?

 

I don't know about the master cylinder, but every time I bought brake stuff for my old 88 GTU I bought stuff for the "hard" non adjusting suspension, 4 piston brakes
