change made little difference but we missed the setup completely track had a ton of bit in heat and the thing was on rails winning the heat. track dried up a little for the feature and first 5 laps car was super tight point to where it was tough to turn without standing on throttle. after that the car was lacking sidebite. we have been having awesome sidebite so we not sure if it was track. he was driving the heck out of car on entry in order to get it to turn then in the middle the rear would wash out and become almosy completely sideways. very frustrating night. left side 52% rear 57. im wondering if extreme lru bar angle is some of the reason. rear springs are 175 lr 200 rr both on sliders. any suggestions. thanks

Mulberry bush and need all new info on car, angles, locations, offsets, air, ect... Going to be thinking about it! Read all my post you can stand to and try to see what is happening! Very hard not seeing the transitions first hand! No side bite to make or rather let it roll! Left side holding it down with extreme angles or indexing changing steer in some manner! The ills are great if ( using force on the left, instead of freely letting the right do its thing ) to get it done!

At static I never nose the right! Most cages and chassis by designs have angles pre-set in sheet metal design in higher rear! Its more for air but the weight at the wheels ft to rear is sloped to the rear! The more rear the better transfer and the less air drag you need to hook! A percentage of air under as well as over can lighten the air load more than the 150 pound correctly placed as (toted pounds) with better transfer of pounds for traction of the chassis with out the added air weight in down force and drag to get it there! Tote the lead or tote the air that slows you down! Both have limits in placement and location for good!

what happens if you lower the pullbar on the rearend?? I have lowered it all the way on the frame side, seemed to not help much for forward bite!! it is all the way up on the rearend side, but there is adjustment holes to lower it down!

Lowering it on the rearend increases the amount of leverage created by the rotation of the rearend. To put it simply, it cause the spring/biscuit to compress more. The higher it is, the softer the spring required.

I run a mini biscuit bar by quickcar..it has all red biscuits in it, (4 I believe) would lowering it on the rearend help with forward bite?? I run a wissota A-mod.

It may help. If the red biscuits are the stiff ones, it could be too stiff for your set up. Lowering the pullbar on the rearend should cause them to compress and absorb torque like they are designed to do. I would try it.

Back angle most important to the diff.! Pull bar angle for lift or drop if needed! If traction is what you need, give the right side a better chance in helping out! This by pounds, transfer, and thrust angle! Be sure to get rid of un-needed roll, roll out, hike and steer if you do! This will give your pull bar a fighting chance to stay put and do its job! One car we had was well equipped for change with a 12 wide rear bracket and 5 different ft positions! We had bars preset for three of them and they changed them around with tracks and setups to find each happy spot! There was none as too many unadjusted factors in the mix! Once seeing this too creates new factors, we then put it in place first and set the car to it's needs to keep it there!
