Im Gonna be building my first G-body car. An 1987 buick regal. Hoping for mid tens with a 500 hp small block with 150-200 shot of nitrous and a nine inch out back. What is the best set-up for the rear suspension of hard launches? I want to keep it stock type and on a budget but want something that will work? Is it just adjustable uppers and boxed lower control arms and a set of moroso trick springs and a set of drag shocks work? Just dont wanna spend a bunch of money on something that wont work. Also what is the biggest size tire i can stuff under the stock wheel well without modifcations. I plan on running a drag radial. Any help would be appreciated.
