This goes back to last season. I took the car to a reputable chassis builder to replace a cracked mid plate and while there asked him to reset the suspension because I always thought it was too tight on compression. They pulled the Afco's off and put Strange on it. I also put the Hoosiers (18650) on it at that time. It has spun downtrack ever since. I took it to original builder and it came back with present settings. I put the Afco's back on and a new set of 3183 Mickeys before last weekends passes. I'll get the Racepak posted on here soon as I can get Cash to do it. I'm severely computer challenged


I think Hoosiers and the Strange shocks were both a step in wrong direction regardless of where four link is set up at.
Do you have any technical reason you think the afco is a better shock then the strange?
Only that Agco has nearly twice as much adjustment range than the Strange. Might add that Afco's were on there back when there was no spin problem.

a good friend of mine is a serious auto cross racer and shop owner and has a very nice shock dyno. He showed me what the afco shocks do at high speed (shock travel), the amount of aeration of oil was so bad that he said he wouldn't put them on anything. The valving caused that. The strange shocks use koni internal valving, he showed me those on the dyno and they were astronomically better. And then he put the JRI stuff that he uses on the dyno and it was again a huge improvement. From what I've seen, the strange shock is far better at being a shock absorber then the afco.

lots of brand loyalty replies and little if any problem solving advice, no surprise.

pivotdoc, following the advice of most of these replies will only result in a lighter wallet. There's nothing wrong with your hoosier tires or afco shocks. Your error was having this "reputable chassis builder" reset your suspension that was working and allowing his to replace your shocks with the brand he is a WD for.

You've done right to put the afco back on, now get the tire back that was working and return the suspension to it's previous set. If you don't have the previous setup recorded, pick one guy you trust and listen to him.

There are countless guys with suspended dragsters and your power getting down the track in bracket and SC mode without issue, running Afco shocks and Hoosier tires.

Good luck.

For once I almost gotta agree with Ed, only difference being the Hoosiers went on at the same time as the Strange shocks, and I had run the 3183 Mickeys for two seasons - no issues. I agree the car should come back to behaving itself regardless of shock brand or tire brand. I have both to use.

that's because you have been listening to the wrong people. Wink

Without your previous chassis setup that worked, you have to start at square 1 and with the car on scales. Then run whatever tire and shock you want and unless the track is total garbage, it will plant the tire and go straight down the track.

Point is shocks nor tires are your problem and your "reputable chassis builder" fuc'd your car up.

Is this track bumpy down track? If not, what exactly is the shock supposed to be doing?

Ed does have decent "opinionated" advise...

Save and spend the money for beadlocks, go with the little bubba, put the car on the scales with new tires and set suspension correctly. Then prepare yourself for the smoothest burnouts and spin free passes you have ever made in your life.

I would think the shock should extend rapidly enough to plant the tire, then have enough compression to keep some weight on it yet enough "give" in the compression to roll over bumps easily. Both tracks were decent but the 1/8 mile was really green no rubber down.

it's advice

and Ed has the knowledge, 1st hand experience and ability to straighten his car out in an hour or less if he/it was within a reasonable driving distance.

more stuff you don't need that will not resolve your issue and will only lighten your wallet.

The compression actually has very little to do with a bump down track. The rebound does. If the rebound isn't setup correctly it will hang the wheel and tire and not extend back to the track quick enough. That is why door cars bleed off the rebound down track. Low speed compression will help you down track with aerodynamics mostly.

Pivotdoc, I looked up my old settings on my last Cameron car in my scale book.

It was 6 inches up at 55 1/2 inches out with 31 percent rise with the ride height at 3 3/4 inches at the midplate.

Hole locations on front bar should be 4 down on front hole and top hole on rear end housing.

Bottom hole is 7 down on front and bottom hole on rear housing.

Front is 554 lbs ... LF 278 lbs 14.8%
RF 276 lbs 14.7%

Rear is 1326 lbs .... LR 641 lbs 34.1%
RR 684 lbs 36.4%

29.5% weight on front and 70.5 % on back.

Cam Height 19 inches.

Disconnect anti sway bar and put one 1 flat preload in lower right four link bar.

Connect anti sway bar and put one full turn of load on right hand side.

I ran hoosiers and Mickeys with no problems with either and Afco shocks behind rearend.

Hope that helps.

If it was good before you made changes and now it is not then those changes were not the right direction for that car.

"Dunning-Kruger Effect"
-a type of Cognitive bias where people with little expertise or ability assume they have superior expertise or ability. This overestimation occurs as a result of the fact that they do not have enough knowledge to know they don't have enough knowledge.

Before you argue with someone ask yourself, "Is this person mentally mature enough to grasp the concept of a different perspective?" If not there is no point to argue.

Hmm interesting. My ride height is maybe a full inch higher than that. Bottom bar needs to go down one hole, top bar spot on. Preload probably needs to be top right bar since bottom bars are X'd. Antiroll not sure of yet, McAmis videos talk about neutral but I've always ran some. Checked pinion angle again and it's not as much down as I thought maybe .5*.
