Guess I'm going to have to add some weight to the front of my Duster. Just wants to keep getting higher on the wheel stands. Went to Goodyear front runners & lighter wheels last year. It started to come up more losing that weight. Now I added TTI step headers & she got worse. Going the hang 10# on each side. Hope that does it to get things back under control. No wheelie bars here, sorry don't like the look on my car. Car still went 1.40 60' w/pedaling it to get it back to earth. Ran 10# in the Goodyears as well. Any input would be great. Thanks, Ken Michalik

Hey John, it's a Ladder bar rear w/stock front suspension w/90-10 shocks. It has a Turbo 400 w/trans brake, Dana 60 w/4.88 gears. It weighs 3060 dry, not sure of race weight. The stall is I think 5200, leave at 3600 & let it flash from there. The rr tires are 31x14 Good Years. Like I said it always ran the tires about 2 feet in the in the air. Took some weight out of the front & this is the result. Like I said I'm going to try bolting 10# to each side on the front of the frame horns. Think that will put things back in place. Thanks, Ken

Adjustable front shocks will help slow the rise down. 90/10 is really loose on extension. If you can lower the front position of the ladder bar that would help too. Maybe even consider front end travel limiters.

If all else fails, you can drop to a 4.30 gear. It might not cost you more than a couple of hundredths ? From 4.88 to 4.30 is a 12 percent cut in torque off the line. The good thing is the converter multiplies torque longer with less gear.

My vote is front shocks, need to slow the front end down.

Frankly I can't believe I read through this and the OP( who I am sure is a nice guy and has a beautiful car) is unaware having non adjustable 90/10 shocks on a wheelstander wouldn't be the first thing to throw in a garbage can. Even a cheap CE type 3 way shock set on 70/30 or 80/20 would have an immediate impact .. Much less a higher quality shock.
