I went through some chassis tuning on my old pump gas Duster to get the best results.
I would lower the ladder bar to the lowest hole on the chassis and then next raise the launch RPM if the ladder bar adjustment helps
I did end up with Koni SPA front shocks and Strange double adjustable shocks on the rear, I think it would run low 1.40 to maybe high 1.30 60 ft. times on 315x60x15 M/T ET Street radials launching at or above 3300 RPM
It was 49.5% on the rear weight distribution with me in the car weighing 3450 Lbs. full of fuel. It ran a best of 9.993 at 134.7 MPH in the late summer at Woodburn corked up on Oregon 91 octane non ethanol pump swill
It ran 10.69 at 124.+ MPH the first time out at Woodburn in the fall of 2005, .7 ET and 10 MPH gain with a lot of work and better parts
Test, test and test some more
Ain't learning how to go faster fun
