Got a new car after my rookie year last season and I'm really struggling on the slick. First time I've ever had a car on scales so I'm not sure where I need to be or if I'm on the right track. 1000LF 1100 RF 225 LR. 150RR. 11 inch springs in the front 13s in the rear. Car has 54% left side, 49.5 % rear, 49% cross and 110 lbs of bite. Way Loose on entry push in middle and a little loose off. 3.5off on LF 3 on RF, 3 on LR, 4 on RR. 22 gal cell and battery are both on left side, and I weigh 300. Thanks in advance

Too much split on rear springs try a 200 right rear, after you switch spring reset your current %'s back to where you have them now

What type of tire do you run? If your tires leak a lot of air from your last race until you scale then I would set them a few hours before and check them often until you scale. Get a stagger tape or equivalent because tire size will definitely change your %s

No experience with DOT tires but advice would still be the same

A 200 ft. split with stronger rt. ft. but with lt. loaded 100-200 more than right on scales with driver! A 25 stronger left rear than right to hold left rear and cross during roll or more the noseing going in and it will plant the right rear when lifting the throttle to tighten it all but alow steer with roll! Extream caster and correct shocks are also part of this winning package for us for over 35 years! Ck it out on all the classes as I use this on all to win! Bacics are the same other than weight in classes! Many have won by forgeting the common and studing the basics of simple! Two inch off sets up front also adds throw in the swing of ft. steering to react and twist the frame more to transfer pounds with out roll or having to wait on the car to react to the track! Having 4 wheel steer in controll of the driver and pounds changing with it can give driver control rather than track conditions, angle change or traction change when the driver has all at his finger and throttle control! Traction should be equal on the rear when rolled if not more right rear to let roll out push the car left off the corner! 80 pounds of left rear with driver wins for us! Putting all your drive and steer in the left rear goes against turning left or having two wheels pulling with traction or one with less and needing more weight! Pushing the rt ft with the left rear sends the car in that angle of direction so you would need a tricycle or be completely sideways to make that work for you! The straighter or car is the faster it is in the turns even if coasting threw with all four planted equally and little ft and rear steer needed to do so with the right driving the car left!!!! Some can see this and win as others refuse to agree with basic proven fact!!! If you never loose left rear but gain right to mach with more added to both sides during transfer traction is a lot less of a problem if gaining left rear and right than loosing left to get more right!!!!

If your running a flat track that would be good,if your running a high bank track need more cross and more rear precent,52 to 54 on cross and 60 rear and 40 front and if your loose after that on exit put 2 turns in left front

Also on that note beef up 3rd spring 1300 or 1350 rest looks pretty good
