Camber Bolts

Has anyone used BMR Camber Bolts? I installed a Steeda stage one lowering kit and looked at their camber kit and don't want to slot my new d specs. Will these bolts hold up for autocross. I may go to camber plates at a later date but if not, will these be strong enough? Thanks
 
My B&R camber bolts held up to three different track days. On the track I run the stock bolts for more -camber. My car is lowered also, for the street I use the camber bolts for tire wear concerns. Just make sure they are installed correct so they dont rotate on you.
How do you like your D spec's? Im going to install mine sometime next week.
