10mm or 15mm spacers?

Guys....
Running my car on 19 235 35s and having problems with the tyres on the front. It's scraping on something and killing me on replacing them. Its only the front ones that are wearing. Obviously my cars lowered but I don't think its that low. Thinking getting some spacers to see if that will work. Was originally thinking 5mm but im guessing that won't do much so what you guys think? 10 or 15mm? any one else had this prob? I have found them pretty cheap on eBay.

Cheers, kev!
