Was gonna say thats a bit steep!! I was hoping they would be around 20 like the ones in halfords!! And to answer previous replies, im running 15 inch alloys with normal dunlop tyres (whatever the size standard tyres are!!) And dont know how low im going to go, what it low and flat so will adjust accordingly when i get my coilovers put on, i just didnt like the fact that my rear wheels arent as wide as my front ones so thought spacers would be the answer!
