Miminum et bbs lm repl. for z18 Porsche Calipers

[walterio]

Is it possible to install the z18 calipers Porsche Cayenne on a BBS LM ET30 or ET35 without spacers ?

which is the minimum et that i need ?

I have BBS LM replica et 42 and only can put the calipers with 23 mm spacers

The result, is et19 and the result is horrible, because the wheels are outside the bodywork.

Help

Thanks
