What is a good starting rear percentage for a stock car based on the Lubbock rules. Take of slicks, 3200 lbs, and run what you brung motors. Is it like a mod? Is 58 to 60% the fast way.

Surely you guys scale these cars and have some idea as a good starting point.

Generally on a stock car, where the #1 has to be even with the front ball joint, you will be hard pressed to ever see 58 rear weight without adding 500 lbs of lead to the rear of the car. Depending on the motor, the tire and the track adhesiveness, you will should look in the neighborhood of 52-55 percent rear for a car like that. The more motor, more rear you are gonna need. The better tire you have will allow you to run less rear. If the track is tacky, you can get away with less as well. I hope this helps a little.

Thanks for the input. I was wanting to start at 55% and the rest of the team was pushing for higher rear%.

Adding 500lbs is no problem. Most well built super stocks in our area are about 2700 some lighter. This puts us adding 500 lbs somehere on a 3200lbs rule. I think a weight rule like this is prehistoric. 3000lbs outer limits and 2800lbs is more to my liking. The tracks should look carefully at how and where guys mount lead before they use a rule like this. It's not safe.

Mosr guys say it is to keep heavier cars competitive, this just is not true. Look at who wins these races. Lighter cars with the ability to move the lead to achieve exactly what they want.

Thanks
