Iv got a set of mk5 fiesta 15s on my mk3.5, tyres sizes are 195/50/15. I also have a set of 40ml lowering springs with coils and i don't mean to sound blonde but can fit them and have no problem with the 15s ? I also have 10 ml spacers on the front for good clearance.

 

This is -40 but 195/45's

 

And you have know trouble ? I would put a photo up of mine but I don't know how to do it on my phone lmao

 

The195/50/15 tyres really need swapping out for 195/45/15 as the rolling radius (and indeed the overall size) of your current tyres isn't suitable.

ET35 is about the optimum offset and rim width of about 7J for the Mk3/3.5 Fiesta.

iirc the later Fiesta's use an ET42

 

Right ok, so basically drop a size in tyres and then lower the car, cheers guys
