looking to buy some rotas tonite and was wondering what the lowest offset you can go on a blobeye 2003 wrx cheers

 

Mine have a ET44, with a 8.5" width, and a 225 tyre.

No rubbing on standard arches

 

wanting to go with 9.5 inch wide just dont no what offset i need without spacers

 

The offset will change depending on the width. To keep the centre of the wheel where the designer intended, you need to add 12.7mm of offset for every inch of rim width added.

If you use offset to locate a wider rim, keeping it clear of the struts on the inside and the arch on the outside, youll completely f*ck up the vehicles handling.

 

Add over the original wheels offset, I should have said.
