I have a full chassis car for drag racing. As a racer, it's all about the proper height and stance, weight ratio and balance(in a nut shell). So at launch time you get good weight transfer and the car hooks up. So my question is....If your weight ratios are good front to back and side to side. Why would you put limiters on your front suspension to stop the weight transfer? Doesn't that, in a way, unload the chassis?  Or am I way out in left field somewhere? Maybe I shouldn't ask that...

I always thought of limiters as a band aid fix to help with wheel stands.
Aftermarket front suspensions for the most part are limited in travel by design.
With my stock front end junk anytime I ever limited the front end travel or slowed it down with shock settings it always hurt the 60 ft. times.

Stud mount?
My car is a ladder bar car too. I bought this car last year. I've been pulling my hair out ever since. I've got the car to run the best it ever has. 9.27 @ 143.35 with a 1.31 60'
Previous owner's best 9.60
Back to what I started, I just never agreed with the setup on my car. I was wanting to know more about this limiting the travel of the suspension.

In that case its used to pick up the extra weight as soon as possible.. as the engine torque gets higher its getting easier to lift the front end.. the next step is to put weight on the front EDIT Thats done mostly on a ladder bar car.. with a 4 link you can change the IC

I've never felt like this car wanted to stand up on me. But with the front end tied up, it feels like its fighting itself.

Used to stop unnecessary movement up of the front suspension. If you can get your car to hook with less front end travel it will 60ft better and et better. But only works if you don't lose any traction. Some people uses it to control wheelie prone cars if there shocks are unable to control it.

That makes sense. But my car feels like its fighting itself at the launch. I'm not totally sure.

Hi Mr P Body! I love hearing from you.
Well I had a Mopar Mege Block up front. It never felt like it was going to stand up on me.
With 47% front I'm a bit surprised it doesnt want to
stand up some.. try taking them off... what rpm are
you leaving it at and whats the stall

I've been launching at 4000. At 4500 it's a little violent. Feels like the tires are spinning or something. Car seems to shudder a bit.
I'm not for certain what the stall is. Motor is out of it at the moment. A new one will be going in.
Thats why its not trying to stand up.. for a chassis
car thats sorta low rpm.. and yes the ladder bar cars
can get violent... make sure your front of the bars
are in the low hole
I'm trying to remember right off hand. But I want to say that they are in the middle hole.
The lower hole has less hit to the tire and holds
the hit longer.. it also has more push forward

Back to what I started, I just never agreed with the setup on my car. I was wanting to know more about this limiting the travel of the suspension.
I'd take off the limiters, set the strut to full soft and see what it does. if it wheelies too much then tighten the extension. I highly doubt you'll need the limiters.
Strange makes 2 styles of struts stud mount or eye mount. The stud mount, the more common of the two the adjuster is on top of the strut...

Cool! I wondered how to adjust the front shocks. I was hoping it wasn't just the limiters.
