Along with the other mods ill be putting on my car, Dress up kit, tinted windows, i want to upgrade from 15" to 17" wheels however reading online it will say the speedometer will read 3.7mph over and that a map change would be needed, How do i get this done?

As long as you fit the right size tyres the hearing and speedo should be ok, 205/40/17

Fiestas that have 17s as standard usually have a steering rack limiter fitted to stop rubbing on full lock, not sure how they fit but I think they are only a few £

Limiters simply clip onto the steering rack.

You remove the clamps holding the protective rubber boots in place, pull the boots back, clip the limiters on near to the steering box and replace the boots with the new clamps included in the kit.

Be aware of the extra cabin noise when switching to 17". It's quite noticeable.

And the extra discomfort/backache/sciatica.

Try one first.

I think my test drive car had 14's?

My Tit arived with 15's, MUCH harder ride, I have to use a cushion.

But then, i'm an old _art :)

Moanmart2 im an old_art and I roll wiv 17" cos I is dead hard.

Big wheels always stand out on any car and the Fez is no exception.

Yes the ride is harder but if you want to turn heads you have to go BIG.

LOL, I bought mine to drive not to pose :D

I put 17s on mine when I had the fiesta mine always were 15s before and the speedo wasn't affected and I didn't need the steering rack limiters in the end either as there was loads of room. The ride also wasn't as bad as I thought either

Me too same as above
