Vim, 8 spaces after { <ENTER>

I need to use four spaces as indent in project I'm working in. That is my .vimrc:

"Autouzupelnianie nawiasow
"inoremap { {<CR>}<C-O>O
inoremap { {}<LEFT>
inoremap [ []<LEFT>
inoremap ( ()<LEFT>

syntax on

set autoindent
set number "pokazywanie numerow lini
set modifiable
set write

But when i hit { and then hit enter i've got:

{
        <8 spaces> SOMETHING

Depending on the filetype, a filetype plugin may be overriding your vimrc settings. Check in $VIMRUNTIME/ftplugin/{filetype}.vim and $VIMRUNTIME/after/ftplugin/{filetype}.vim. Also $VIMRUNTIME/indent/{filetype}.vim and the after version of that.

I faced the same problem.

The solution is to command this after a colon :

set autoindent
set tabstop=4

Or you can command:

set tabstop=4 autoindent
