I run a CRG Blackstar with a LO206 on asphalt sprint tracks. My weights are:LF 75, RF 70, LR 106, RR 116. The balance is 40% front and 60% rear. A couple of questions. What is the best and hopefully simplest way to balance out the front across and rear across? In other words, 72.5 at both front wheels and 111 at both rear wheels. Also, if I want to shift some weight forward to achieve more of a 45% front and 55% rear would I do this by lowering the front or raising the rear?
What you have is cross weight. You can probably get pretty close by simply lowering the right front spindle one washer. That will probably add 3 to 5 lbs to the right front and left rear. If that’s not enough then raise the left front spindle one washer. Your chassis probably has a little bit of twist in it which is somewhat normal for a used chassis. Many times the twist can be easily taken out but will usually return if you run predominantly at the same track.
If you have room to move the seat forward an inch or so that’s what you should do. Many times you can move the pedals forward the same amount and remain comfortable. If the seat is as far forward as possible then take your 5# weight and move it to the front. Your side to side is very close as far as seat position. Assuming your camber, toe, stagger, and air pressure are all set then the Rf needs bent down slightly. Probably about an 1/8″ at most. You can get the fronts even and the rear within 5 if you get it perfect.
As mentioned do not move your ride height to change front weight. It won’t do much anyway.
