I ordered online from vauxhall-accessories.co.uk, a set of 4 genuine GM 17" 7J 10 spoke Alloys for my Asrta J. On the webpage there are two panes to choose from: 1.: 1.4/1.6 petrol and 1.3 Diesel---2.: 1.4 and 1.6 turbo petrol and 1.7 and 2.0 diesel. As I had a 1.4 turbo petrol, Ii opted for the right hand pane and paid £492.00. I asked for the alloys to be delivered to my local tyre fitter. I ordered the correct tyres for these wheels and when the alloys arrived, the garage fitted the tyres and rang me to pop them onto the car. When I arrived, the alloys did not fit!!!. After two weeks of phone calls and messages left, they have finally picked up the faulty alloys from the garage. Using my local Vauxhall dealer, I have clarified the problem for them. Only the 1.6 petrol turbo and the 1.7/2, 0 diesels have 115 PCT stud array as they have 300mm disc brakes-----therefore the 1.4 turbo petrol (276mm brakes and 105 PCT) should have been included on the left hand pane. Although vauxhall carry the correct alloys in stock, they are insisting on a refund, rather than send correct alloys. Anyone else with a 1.4 turbo petrol Astra J beware.
