Anyone here change out a ladder bar setup for a four link setup with no other changes.
Was the change it self worth the money? Did it make your 60ft that much more consistent.
This is on a well sorted out bracket car, always looking to take it to the next level.

I think the car is already deadly and is a beautiful ride.
You should put your money into hiring a top notch driver for it

If a ladder bar car is correctly set up, I don't think that a 4 link will be an improvement. A 4 link is really just a compact ladder bar, with more adjustment points, most of which will never be used.
I would think you would be better off spending that money on better shocks.

Don just think how good this car could be with a good driver, you know any lol

Shocks would be a cheaper option, only have single adjustable strange on the rear now.
Has double Afco on the front.

I would think that if you have to use a lot of shock control for best 60 ft, then maybe a four link will show an improvement, but not much if you are real close to the best 60 ft for what you have already. How do your 60 fts compare to some of the best cars out there, preferably similar? Can you post your best, and average, and worst?
On my ladderbar setup, the best thing I ever did was build an anti roll. It made a great deal of difference, both in 60 ft gains and consistency.

Unless your trying to make 1000hp its not worth it, fine tune what you have with weight and shocks.

It's been 1.31 60ft in below sea level air
But on average it's 1.34 to 1.37 in the same day. better early in the day the car goes wheels up so you can tell when it leaves good or if it slips the tire. Am I just getting greedy wanting less then a .03 move in the 60ft in the same day?
I'm a bracket racer so I'm looking for that little bit of consistency I feel like I'm missing. Don't get me wrong this car is pretty good and has won it's share of races.

.03 is quite a bit of movement in 60 foot for a bracket car IMO. My car is slower(1.45 in average air), but it usually moves less than .01 in a day. Caltracs and a 29.5x10.5W M/T, nothing special.

Your car should be at least that good considering better suspension. Obviously the bigger the tire the easier its going to be to hook, if I remember right you run a relitively small tire? I'd be looking at upgrades shocks or making adjustments to narrow that window down.

If 60 foots aren't consistent, ET's aren't consistent. Focus on the first 60 feet and usually the rest will come together.

.01 is more like it. It has 29x12 Hoosiers on it,
I will have to try a new set of shocks.

Never understood why a ladder bar car would benefit from an anti-roll. If you have trouble adjusting preload you could do it in the anti-roll bar. But, most modern ladder bars have the easy to use link to set preload. Most ladder bar cars will not roll rotate even when you need them to. But, all cars are different.

A 4-link would allow you to lengthen or shorten you IC with more points to adjust to. Instead of 2-4 points and ride height to maybe cheat and get a little more in between a 4-link can have three times that many that are useable. But, don't be fooled over half the holes will never need to have a bolt through them. And if you are not careful in bracing the top of the 4-link brackets you are going to have a weaker setup.

Well if you can wait till next spring I'll let you know how my results are Our car is at John Holts getting a full 4link back half.

"Never understood why a ladder bar car would benefit from an anti-roll." Check out the picture, one pass. 1 1/4 x .125 steel tube anti roll wasn't enough, had to go with 1 3/4 tube.

2 The roll rotation problem really gets out of hand with a high SLR and a front mount near the neutral line. It got so bad one tire was coming off the track, which made for some rather interesting antics!
Back to the OP, your car is running 5.30s in the 1/8th right? 1.3xxx 60 fts would seem pretty slow, but the overall performance is great. If my memory of your ET is right, then 60 fts should be somewhere around 1.22? With the right setup and tires, the car ought to post 330 marks within .003 or so like a machine on the same day. Or at least it should on a well prepped track. I'm pretty spoiled with the track prep at BIR in Mn.

You must be thinking of some ones else, my duster only runs 6 teen to 6.20s in the 1/8th
Also I do have a good set of Afco double shocks on the front, have plenty of adjustment. may have not found the sweet spot yet I guess.

Car leaves nice and straight
