my 1998 mroadster is on it's second set of front tires that have worn severely on the inside edges. I need a camber adjustment and do not wish to buy the $300 camber plates as I do not use my car on the track. I just want my tires to last longer. I guess they are leaning in on the top - is that positive or neg camber??

I have read about some 'crash bolt' or cammed bolts that could be installed, but none of the sources listed pan out. Anyone done this and can help me out? FYI- I am a little oversize on the tires 235/45/17 I think. the stock narrow ones just did not look good to me. Oh, I also have the strut brace on top of the struts... if that matters. Please email any thoughts. thanks
