TK,
Hi,
What I did was to raise the top 4 link mounts on the 9" housing 1 1/2". This will now point the top links down towards the front of the car, this will in effect move the instant center of the car and pull the rear downwards under acceleration giving you better traction. Also added a panhard bar[5 th link] this will keep the rear from moving sideways and be way more stable at high speed. Put the battery in the trunk, passenger side with master cut off switch out beside tail light[NHRA required] Add a driveshaft safety loop. I also boxed in the front lower 4 link mounts to the frame, SV just had them on a bolt. Also soften up your rear shocks.
This now launches hard and will beat just about any street car off the line..... 1.66 60 ft times.

How old is the chassis? Is it a stick car? Why are you narrowing the rear? I have 29x12 inch wide rubber under the back with the stock width rear and offset rims, and there's room for more but not necessary unless you're after the steamroller look. Listen to what HighPlains said plus add a pinion snubber & disconnect the front swaylinks & you're well on you're way to two wheel mayhem!
Let us know how you make out!
