With everyone trying to get their LR up as high as possible, what are any issues you’ve run into going too far? What symptoms come into play once you get too much bar angle, over rotate the birdcage, etc? How do you know from the drivers seat when you went too far?

It’s not that the cars are hiking higher but yes the LRs are up higher. It’s all In how we are circumventing body rules to get the LR up

I don't think anyone is limiting their car to 12.5" drop anymore with a 7.5" ride height.

Lengthen chain until car flips then back off a 1/4"

If a little is good, more is better right? Haha. Book calls for approximately 13 1/2”-14 1/4” but not much seems to be done by the book anymore. Everything gets stretched to the limits or the opposite of what the book says can sometimes be exactly what you need. The shocks will allow up around 15” at base settings. Just kinda wondering if people are pushing those limits, or what I can look for in the shop dynamically to visually see “too far”

if you was wanting a serious answer: At a certain point lengthening chain without changing anything else, will induce a ton of rollsteer for a small amount of lift thus just making the car looser. So if the car is neutral now, you will have to make some changes or once you hit that point your going to loosen the car more then you gain from the areo advantage your getting.

Also keep in mind just because the shocks aren't topped out with the rear end hanging doesn't remotely mean the shock isn't stopping the car instead of the chain when the car is on the track and the RR isn't hanging.

What billet said...with your LR hanging, jack your RR up until the right frame rail lifts off the jack stand/lift and then see what you really have left in your LR shocks.

You gain drive by the added bar angle, but you'll have to play with your bar lengths to keep from promoting to much rear steer

Most of the gains are in ride height manipulation if you have a newer car that is already designed for more drop. With that being said if you have a car that is older and that is comfortable now but you want more drop you need to measure everything at your current drop, DONT forget the Jbar too and where your rear end moves left to right (actually chassis rear end stays put) and don’t forget the driveshaft make sure you don’t bottom out on the splines and can actually handle more drop. You will gain more j bar angle so you might need to drop it statically

We were fighting an issue being throttle loose most of the season. I was blaming it on entry not being perfect. I was thinking of bar angle, and not so much about the rear steer that that added droop was putting in the car. Getting the droop set right made a huge difference. The changes we were making before to try to stick the entry seemed more effective too.

so on an 2008 gen x approx amount of left rear drop is ?

Pretty much any year GenX, 13" is a good place to start. You can go more but you have to be ready to deal with some of the stuff already mentioned on this thread.

13 5/8" for a gen x is pretty much the sweet spot. You need to lengthen the top and bottom rods to put the LR back in the same spot as if it had 13" that way you are just gaining bar angle along with getting the LR higher in the air without increasing the rollsteer.

I always ran 13.5 on my MasterSbilts with no bar length change.
