I've seen several on here post that without driver they run 60 percent rear....when you are acheiving that do you mind saying what your total weight is without driver.
I ran sixty rear this past weekend, I liked certain aspects of it but my weight without driver was like 2,440 pounds. I run a 2 link so I ran stiffer rear springs to account for more weight.....fifty pounds stiffer on each side....it wasn't that bad......

Put softer springs back in and try again.

We run 59-60% rear without the driver and usually weigh total around 2400-2425 without the driver and ready to race. We have to meet a 2500 minimum after the race so this is the lowest we can run and safely make it on a long fuel burn. We also run 200 and 175 springs across the back. I dont know what you are using now but we had problems with soft springs because there was just too much weight there and we stiffened the right rear up to help hold it up in the corners otherwise the car would just fall over and not come off well.

Some cars are not capable of getting that much rear without weighing heavy on the total weight. We had an old sardeson and had to bolt 250 pounds on the rear to get 58-59% whereas a Dirtworks takes hardly any to get 58%.

Thanks for the second response, I'm just looking for numbers to compare with on total weight at 60 percent rear. The first response says nothing at all......put soft springs back in and try again? My car never liked lead on it at all with soft springs, and this past weekend with stiffer springs it felt pretty good, I'll try it again at another track but would still like some other comparisons on total weight..thanks.

To get up to 60% rear on our DW 2-link, are total weight is almost the exact same as your...2435 to be exact. We run LR spring in front and RR on top of axle...200 and 150 respectively. Driver is a pretty good size, so we never get run it at 60%, usually just bump it up to about 58.5% when it gets dry...somtimes 59%.

workin it,your car is on the heavy side,but if you want sixty percent,that is what you have to live with,you cant run sixty percent rear on that car and be light.If you go back and read your original post,you are the one that brought up spring rate,and said the car wasnt that bad and you liked certain aspects of it.It wasnt real good or you would have put that in the post,therefor I was trying to help the car feel good and be faster.Short of buying a different car you are stuck with the weight,so change something else and get faster,if you didnt run it with the original springs,then how can you know you needed to go stiffer on rear springs,especially 50 pounds,that is a huge jump on the rear.If the springs cant handle another 2 or 3 percent,then I would agree,they were too soft originally.

The reason I bumped up rear springs rates 50 pounds each were twofold.....
I know my car never rolls or bites nearly as good with lead on it in the past, and that was just to have around 56.5 rear.
Secondly, my first night I was gonna try 60 percent rear was also at a track I'd never raced on, but it is one of the higher banked tracks you'll ever run, so I thought given the two cominations that the stiffer rear springs might not hurt as much.
My next time out I'll run a track I have run alot before so I'll know more of how much I like or don't like it. Certain aspects I really liked, however, so I don't want to give up on the idea of alot of rear, I just wondered how many of you run that much rear and have to have as much total weight as I do to get it. Nobody wants to weigh any more than they have to. Luckily I don't weigh alot so that helps. I appreciate any other total weight numbers to compare with....

A heavy car with the right setup will be faster than a light car thats not setup right.
