This is a question that keeps evolving. Most everything I've read or had experience with places the RC between 3 to 5 inches high. Left to right is debatable, I know Rayburn's were up until the last couple of years more to the right than some others and the cars tended to be tight on entry, but worked well on big tracks like Eldora. The Hook setup changed the way a lot of car builders thought about the RC lateral placement. I know for a while some builders worked towards having a migrating RC that moved towards the RF, but it ended up making the cars pretty tight. I knew of one car that had the RC climb up on top of the RF tire during roll. Now I've seen more builders putting the lateral RC more left to help the cars turn better. Bottom line is every choice is a compromise, usually better driveability means less forward traction or a lose in sidebite. The latest trend is to have way shorter LS lower control arms and longer RS lower control arms.
