How low can I go?

you could always cut the coils.....not that I recommend it, but I will be doing it to the front of mine as I don't feel like buying 400 dollar I-beams.

spindles and coils wouldnt be too bad though, price wise. blocks are only 30 bucks at like autozone and shit.

Thanks everyone for the info, I am going to drop it 4" front and rear. Still haven't decided on what rims yet,smoothies or Astro supremes But it will have wide whites tho!

5/6 rides pretty good. my friend has a 94 ss with a 5/6.. it needs a bolt in notch in the rear, do that and its golden.

Yeah, I had a 5/6 on my old truck and didnt notch the back. I beat the bump stops to a pulp.

I got a 98 dime with 235/40/18. I had a 6-7 drop and it took alot for me to hit my bump stops. SO I think a 5" drop front and back with your tire selection should be just fine. If you want to play it safe just take out your bump stops in the rear. Hope this helps.
