ok i got ralliart flares they are fibreglass the inside lip scraps now and then since lowered would like to trim the inner part of the flare whats the best way to do this

I would use a flap dics on a 5 inch grinder

Dremel with the cutting disc would be my weapon of choice

This guy could help

Yep his work is good, highly recommended.

On a serious note, dremel with a cutting tool is the answer

dremel +1 im cutting fiberglass with it atm and its real easy ;)

yep you want something thats going to grind through it, not saw!

i used an angle grinder on my , worked ok, i used a file to tidy up at the end

thanks guys done it today i hope its going to be ok i think must have somthing to do with the offset on my mags as they are only lows a alot of rubbing
