What torsion bar stops do you add/take out turns on to add cross in a sprinter?????

Were you a kart racer?

Cross is a term I had to learn when I quit sprint cars and started racing karts with my son. In sprint lingo, it was usually referred to as LR weight. Cross weight is a karting term.

To add cross/LR weight I'd either ADD to LR/RF or TAKE-OUT from RR/LF depending on what your goal is. OR you can do it with different blocks as well.

Hope this helps.

I agree with Team W. I haven't even thought of cross-weight since leaving asphalt stocks in the dust. With the late model and modified on asphalt, we lived and died by cross-weight. Each chassis had it's own personality and liked a certain cross-weight. Get it right and it's a smooth ride, but miss it by a little and it could be pure evil. I suppose the same rules would apply to sprint cars, LR/RF in or RR/LF out to add cross, but standard sprint setups revolve about block heights. We are relatively new to sprints, so we don't try to innovate. Just watch what the fast guys do and learn from them,

I've seen a few articles here and there on scaling a sprint car, but mostly comes down to blocking. I would suggest Steve Smith's book on sprint car setup. There aren't any secrets in there, but it does give you plenty of baseline setups to get you in the neighborhood. You can tweak from there. Sprint Car and Midget magazine used to run a section on pit notes from different teams. They would share their base setup and adjustments from racing weekends. Interesting to see how some teams adjust (and why) through a race evening.

Good luck!

do you know what bite bolt to turn to load or unload a particular tire? i mean do you know what bolt to turn to put weight in the LR corner of the car for example? my next question with all due respect is are you serious with all these questions on setup ect you post here? you post asking a lot of questions that are very basic. you ask about cross weight. well if you think of the car as an "X" with each of the corners of the "X" representing the four corners of the car you will see that the LF and RR are connected diagonaly. same for the LR and RF. you add or remove weight to both of the diagonaly connected corners to change cross weight depending on what you are looking for. you can adjust cross weight with out using blocks specificaly designed for that. . most people just add or subtract from what they already have the car set at based on what they feel the car needs. if you add RR and LF you can tighten the car up on entry and in the center, but go too much and you may get too tight on entry and too loose off. the opposite is true for LR/RF. you can get the car to drive straighter from the middle off, but you can also get it loose in. i am not the smartest, and others may go into more detail, but that is the basic idea. some guys will get a turn of RR in the car by doing cross. a 1/4 turn into the RR/LF and a 1/4 turn out of the LR/RF right off of say 3" blocks in the front and 4" in the rear would give you a turn of RR but not effect tilt or ride height. no one can tell you what works for you or your car or driver. it is just something you have to find out. work from the center out, with the center meaning the basic setup for the kind of chassis you have and the type of track you are on. make ajustments from there. you will then find what YOUR basic setup will be after some trial and error tweaking of the basic setup you started with. then you can use that as your center to work from. a good rule to remember is......if you turn the bolt one way and it is wrong, turn it twice as much the other way!
