VXOC Astra-J/GTC

More of a question than actually wanting to buy right now after some advice

I want a set of the SRI wheels for a gtc i have seen some un offical vauxhall ones for sale on ebay but they r 18inch which am not too bovered about as tyres will cost less but for the price are they any good does anyone know?

also i have seen a rear spoiler want it in gloss black again seen an unoffical one but its a decent price i think but it says it is only held in place with glue... is this right does anyone know

also i want some gloss black mirror covers wondering the best way to go about it? do i get them replaced or do i buy some covers to go over the existing ones?

any advice would be great thanks in advance

Maxton tailgate spoiler cap is cheaper from the Maxton website, £90 inc shipping. It is fixed on with 3M tape, a few people on facebook have them fitted to their GTC. http://www.maxtondesign.co.uk/product/as...j-gtc.html
