I have a 2917lb Metric I-stock. I added 50lbs lead weight in the left rear a couple of weeks ago so, I am at roughly 2960lbs.

Here are my percentages with the extra weight.

LEFT 53.3%
REAR 50.3%
CROSS 52.3%

Here is the kicker... 176lbs of left rear.

How would you expect this car to handle?

Just a note, adding the #50 over the left rear frame will not add left rear or much cross to a car. 52% cross is on the higher side but ad stagger if it is tight out.

The real problem is that with those numbers everyone would expect the car to be loose in and tight off, but it is actually VERY tight in and just a little loose off.

I like the bite off the corner pretty well, but the tight in is so bad that it almost undriveable.

Possible I have too much front brake....even though I have as much bias as possible to the rear?

Are you saying you only have 176 pounds on the lr when you scale?

No..It has 176lbs of left rear bite after I added the 50lbs. Prior to that it had about 118lbs.

If the track is drying out and slicking up too much rear brake will straighten out the car on entry. Also try adding a little rf stagger.

Did you scale it after you added the weight? If adding #50 on the lr frame rail gave you #58!!! left rear then your frame must be as limp as a lettuce leaf or one or the other scale numbers was wrong somewhere.

It was scaled afterwards, but not on the same scales, so not exactly comparing apples to apples.

If it is tight in due to brakes no chassie change will help, go down on the rf shock(95 to 94) or take 2 or 3 turns off the rf (less weight)
