Hey guys, I'm having a full fram put in at a shop and I had a ladder bar angle concern. I bought the back half out of a car that was in the shop and I don't think the brackets are correct for how low my car is sitting. There is a pretty good down angle on the bars and I have concerns about the car going straight on the launch. See attachment

I don't want to rain on your project but I see a lot of required parts of the cage missing, hopefully there not representing this back half picture as all that is needed, are they? Is the rear suspension in and is the car at ride hieght or cloes to it in your picture? I really don't like the way the ladder bar mounts are on the rear end and where they mounted them in relation to the frame rails
It's very close to it in the sig picture. The cage was not complete at the time but is almost complete now. My main question was the angle of the ladder bars. That was the only picture I had available to show of the angle. The car is still at the shop. Here is a better pic of the cage coming along

That looks a lot better, see if they will fix it for free before offering to pay for the switch to a four link If they can't insatll a ladder bar correctly how many ways can they mess up a four link installation You don't want the car to hurt you or drive you broke trying to make it go straight and easy to drive, does this shop have a good reputation with a lot of cars out there working really good? If not think about switching for the last changes to the rear suspension, let them learn on someone else

that door bar looks high, are they raising the seat? looks like it will be higher than your shoulder?

No it's ok, although I might raise it a little for better vision.

"the ladder bar needs to be level to the ground now and adjustment holes up and down for tuning."
Yeah that's what I thought too, so seeing as how the car is so low, how would you fix it? I think the axle brackets have to be re-welded and moved inboard and different front brackets made. Here's a pic and you can barely see it but it's on the right side where the ladder bar mounts to the front.

yep! move the axle brackets inside of the frame rails, build (or buy)a cross member with 5 or 6 holes for adjustment. mounted between frame rails at the proper height so the car will set that low. from the looks of the frame rails there will need some creative work there to get the cross member that high.
Yeah the car is lowered so much I'm going to have to get silly with it. Since the axle is higher than the frame, maybe I can use a longer lower bracket on the axle to get it level with the ground.

have never seen an offset bracket to lower the bars lower on the axle. i would be afraid that would change the leverage on the chassis. if it did, any normal tuning info would be out the window.
Ok then I guess I'll go the other rout lol, I don't want to start screwing things up worse.

UH...that thing will NEVER launch with the ladder bar at that angle. I'm sorry but your going to be battling a HUGE issue.The bottom bar of the ladder bar needs to be as close to parallel to the ground as possible in order for it to work.Where you have it now the car will only spin on the launch.Build whatever it takes to get the bar level. I'll look at the other pics and see what else can or needs to be corrected. I see some Chassisworks tin in there did you purchase it from them?
