Rear Percentage

[TNDirtRacer]

Since Crate cars are under powered, especialy older cars that were designed to have 600 + HP, shouldn't they run less rear percentage?

What changes would be needed to the lift bar because of this?

Do what works for you.
In most cases less rear % is ok.
If you're not spinning your tires then move the weight forward and let the front tires do a little more work cornering the car. With less rear you may need less wedge. You can move weight forward to 50% as long as straightaway speed doesn't suffer.
Since you don't have the speed of a super late model you also don't need the left side %. As the track slows many cars are over leftsided. The closer to 50/50 the more predictable the wedge, stagger, shock and spring changes become.

Many Americans are over left sided.

HEY! This is a technical site so keep your politics out. (although I do agree)

I think he means over weight.

Just remember these cars are all about momentum. You cant put enough cog to them yank them off the corner. Im not that far off on my percentages between a super engine and a crate but I have backed off on bar angle and lr. Hope this helps.
