the slams are good but contitechs come in 1/2 ports too and are cheaper than the slams. you would use 6" in the front and 7" in the rear on the regal. the front brackets are the same as an S-10 by the way. you could also probally use a 7" bag in the front, but you would need to cut out the spring pocket quite a bit.

you would need to cut the spring pockets a little bit, but it will be more with the 7" ones. the 6" ones are like 2500 firestone/contitechs and the 7" ones are like the 2600 lb firestone/contitechs. you might be able to squeeze a 8" in the back, im not sure. ill check out my homies regal tommorrow. id just run 7s all around and cut out the front. i dont know where to get the contitechs, im helping out at an airbag shop and i chose parts as my pay.

more surface area of the larger diamerter bag equalls more lift with less psi.

just go with the bigger ones, even with alot of pressure you will be happy you did.
