Trevor Posted May 25, 2017 Share Posted May 25, 2017 Sometimes you can see it stamped into the outside edge of the disc otherwise its a case of taking the wheel off and measuring it up Quote Link to comment Share on other sites More sharing options...

Hoggy1972 Posted May 28, 2017 Share Posted May 28, 2017 I just did my fronts this week. If you look on the chassis label either in the boot by the spare wheel, or in the handbook you'll see a 3 digit code, 1ZL or 1LG. If it says 1ZL then they are 347mm, if 1LG then 321mm. Hope that helps. 1 Quote Link to comment Share on other sites More sharing options...
