what back spacing do you all use. I run a metric on a 5/16 mile 12-16 degree bank and starting point tire pressures. I've been running 10lps left side and 16 on the right if the track goes slick I'll bump up right front 1-2 lbs.

If referring to off-sets of rims to each his own to get their set-up to work! Ours is a middle of the road type set-up than most, it doesn't effect the car so much as the driver! Twos all the way around gives the springs less movement to hold poundage with-in ranges better! Also more spares as to not having spacers to get it corrected, so less stud weight! More ways to keep roll out where we desire as it gains weekly! Tire air changes a lot like offset and spring tension! That too we try to hold at a norm to be able to adjust the car! Each thing has a job to do well to work correctly with all the rest! Point in case, you started with left weight! So why tuck under to loose it by uncontrolled track conditions or bumps! That's the springs and shock's job! Pressure is pressure at the tire or spring on traction of the wheels, all four! Any added movement broadens the ranges each has to follow! So by off-sets, leverage and correct preloads of springs and air, the chassis should move easy but little by coil bind of springs and not be thrown into a decision of have-too to work properly! A smooth calm ride with quick transfer and less movement! It sounds good anyhow! Getting there is sometimes troublesome if not totally committed to the change! Few set-ups react to any change in the same way! Some of the best rules of thumb has thrown me off badly before such as tucking the right rear in loosens the car! The weight over came the tire pressure! Aired up it was tighter than before tucking, as the tire never let it roll! Both gave the car a mind of its own in the turn and never a constant reaction! Driver effected!!! A lot of people may think the drivers don't know how to drive but its mostly set-up being indifferent to the track and reacting differently each time! Its like you having to adjust your driving to each change made on the car! How would you ever learn if different constantly?

Each change gives clues to the larger core causing the need to adjust! A norm on air for us is 2 pounds right to left, total weight and transfer sets the poundage by surface area of contact sitting on concrete! With a added 2 pounds per inch under eight inches flat on the floor lt.rr. to 6"s rt.rr! The ft is norm 2 pounds more ft side to side from rear! Total weight, spring rates, leverage, pounds, -- We have no high weight at all to cause roll!
