No, K&N install was very easy, just remove stock airbox and attach filter to MAF.
I got the three inch springs from summit, part number was BEL-4228 I think. They were $99 plus shipping. Ride was affected, it turns much smoother now but the back is a little rough but that's b/c I haven't gotten a chance to cut off the bumpstops yet, the front rides completely normal!
I know I need rims but as of 2/21 I wrecked my Blazer:bash: , did $4000 worht of damage to her

I might loose my license so plans are kinda on hold. If I don't lose my license I'm going to do exhaust in a week or so, glasspack to a side exit but I need to find some nice looking tips, any ideas? If you guys have mroe questions about the drop feel free to e-mail me!
