Hopefully I find some scales, then I will try springs. Looks like the rear is getting hit pretty good, softer springs would allow more movement?
No, the shocks control the rate of movement (when valved correctly) which also impacts how much movement will take place. The springs store energy and then release it during extension.

Can not tell first thing about suspension, have not had one since 1988. I will agree that if you are using weight to make car work. It only makes sense that correcting the issue and removing the weight would be best. Plus with removing that much weight car would pick up twice one suspension and two lot less weight.

Since October I think the chassis guys telling me QA1 are bad are not normally dealing with cars as slow as mine.
I hope the converter is one of the main remedies but I think the 150 lbs is coming out to start with.
If I can get some scales that might help as I have a heck of time getting the truck to sit level with driver in it.
Appreciate everyones input.
Toad1, side to side level or front to back level?
Video works. I assume you don’t have an anti roll?
I did not have it attached on that video. We tried it for a couple races and it made the truck almost rigid and 60' varied a lot more. I was surprised as it looks like it really needs one. Still on there but the links are not hooked up.
As for the question on getting it level, front to rear was good but side to side problem I think was a set of front springs that just gave up. Took them out and they were not close in height. Ended up having right front spring cranked up 1-1/2"-2" more.
Thinking the TRZ A-arms and regular coil-overs would have been better choice than the QA1 Pro system with the tapered coil spring and urethane mounted coil overs. It was just budget concerns and I think it bit me. Truck was awesome the first 150+ runs but got goofy at the end of the year.
Jok, I don’t know how this truck could ever have been working “awesome” your definition is clearly very different than mine, when the truth is it’s AFU…wrong springs, junk shocks, 4 link setup unknown, never been scaled and you needed to add a 150 lb. bandaid to go get it down the track.
See if you can’t get pictures of current 4 link setup.
Put anti roll back on
Have the car scaled and 4 link adjusted by chassis shop
Call Shane at competitive suspension and get front shocks and rear shocks ordered. Having car scaled will give him info he needs
Put car back on scales. If shocks on it are currently messed up and different heights then you may need some more minor adjustments on the scale with new shocks
Yes it’s money, but that’s the quickest way to get it right
This^^^ the car was never setup correctly.
Jok, it’s not hard to achieve the “awesome” display of perfection in motion of my Firebird with your S10, all that is required is scales, a tape measure, a digital angle finder, the right springs, shocks and a few hours time.
and here's my friend's 427 small block S10 back about 7 years ago.
If you are looking for a set of shocks to get the truck going in a better direction, I would give Competitive Suspension a call for sure. Shane and those guys can 100% get you steered in the correct direction.

You're off to a bad start, unless you can explain how front to back weight percentages are a band aid, as you've stated in this thread.
your words not mine retard. The bandaid is bolting 150 lbs. in the car to hook and go straight down the track.
stick to the street/strip junk you turn wrenches on, installing 80s technology for the local naive and clueless.
It wasn't perfect but it got me to the finals of a $10K and two other final rounds as well as about 70 other round wins. It Fell off later in season and got to where it dropped .02-.03 sometimes.
I didn't buy a working pro-built chassis like a lot of people do, I built it from frame up and paid for about 1/3 of the truck in the first season racing it. I will get it better and appreciate everyone's input.
Jok, this isn’t about wins or checks, if you want to make it about that, I ain’t skeered, I’ve got the wins, Wallys and checks. Further, theres alot of junk that wins because the driver has skills or at least more skills than the rest of the ducks at his local pond.
That said, you asked for help and I offered first hand experience having set up multiple cars, If you follow my advice your truck will work better than it ever has and you will run quicker and faster because it will be 150lbs. lighter.
Oh and FYI, I built this car from the frame up…
Ed, after reading through and looking at your scale pictures.. You have 100lbs preloaded into the RR (passenger rear) tire, correct? What kind of suspension does that car have?
I always thought the rule of thumb was 75-100lbs more weight on the LR (driver rear) so that when the car launches and the engine torque tends to rotate the car so that it equals out the weight at launch and it goes straight. Not trying to question what you have done, its obvious when watching that car leaves it has been tuned very well but also trying to learn and understand.
For reference our 71 camaro ladder bar car weighs 2800lbs starting line weight (aluminum block LS), and is 50/50 with the front corners being equal, and rear having 70lbs more on the LR tire.

69lbs., you thought wrong and it’s a 4 link
My bad on the number.. lol
Care to explain a little more? Like I said, I'm interested in actually understanding the reasoning behind either choice.

Hey Ed, no issues with you or the advice.
You probably don't want to compare wins and Wallys with me but that's fine. Our track is anything but a duck pond, it is a Snake Pit. SFG race is 3-$25K, 2- $11K, 3-$7K, 6-$5K and I doubt competition can get any tougher. Most good bracket tracks are similar across the nation. Put up the money and the guys who lay down solid packages all day show up. Cedar Falls Motorsports Park is a Tough place to win which is a compliment to those that race there.
You have a couple nice cars, like thousands of other ones. Same for my S10, it's just a truck with a 71 year-old driver trying to turn on win lights, so far, so good. If the truck gets better the stripe gets more predictable.
Sure didn't mean to put down your cars or knowledge but sometimes I am misunderstood. Maybe we meet someday, who knows, I might have a couple years left doing this crazy stuff.
