I'm running a metric car that weights 3250 lb
Weight % are rear 47% left 53% cross 52% Spring rates are rf 1300# lf 1100# rr 200# lr 225# Problem is that the car wants to nose dive and roll to the right really bad. The suspension in the right front and rear is bottoming out. The car seems to be pretty fast and the handling is not to bad except for the rolling. Any suggestions Thanks in advance.

Evans,
I'm sorry I forgot tire pressures 14lbs on right side and 10lbs on the left side.

34 i ran 20 rf 18 rr and lr and 14 lf. i also ran the same shocks as you and it didnt feel like it rolled over. i never had a problem with the tires rolling either but i like driving deep in the corners that is why my front is a little higher . another thing you might try is a 1350 on the rf and see if that takes some of it out. i tried it but it didnt fit my driving style. also check your bushings up front like in marples post.

Evans,
Thanks for the info. What is the best way to check the bushings? The A arm bushings are stock parts and have never been changed.

look to see if the rubber is pushing out excessively, weather cracked real bad or pieces missing. that is a sure sign that they are bad and being orginal equipment they are probably worn.

In my car the bushings were so wore out you could pull the top of the tire and the whole A arm moved we put new bushings but it was a paine in the ****

Since I only have 47% rear weight will that make the car nose dive and bottom out on the right front because of the front end weight?

are you sure those springs rates acurate how much brake you using to set it up do you use both feet or just the right foot

Hey Evans the car is already 100# over weight. Should I just add weight to get the right % and not worry how much over the car weighs?

Flatlander the spring rates are accurate and I use both feet when driving. I don't use very much brake at all just enough to set the car. The track is a 3/8 mile high banked very fast track.

Thanks for the help.
