so i know there have been a million threads on this, but i cant find specific answers to my questions so here goes.

i have oem staggered 87's and have just added lemans flares. i want to add spacers to regain the poke that i had before i added the flares. I definitely want to go at least 25 in the rear and want to add fronts as well. i have read that adding different size spacers in the front and rear can cause suspension issues. true or false? also, i want to be able to re-use my stock wheel bolts so that i can keep my wheel locks. from my understanding, spacers smaller than 20mm cannot be made in the DRA style (re-using OEM wheel bolts). true or false? would i have problems if i went with 25mm all around, 30mm all around, or 25mm front and 30mm rear?

thanks so much in advance for the help
