We have a new car and the front end is setup way different then most we have run IT is so different that when putting a two inch offset on the rr it tightens the car up

When you go back to a stright up or 3 1/2 offset is lossens the car up

Question is how can i make the car better on entry and not mess up exit iam running a inch rear stagger and my car is tight anyways so i have to run 175 on the lr and the 200 on the rr to make it work

It comes off the corner HARD and straight

1200 rf
1100 lf
200rr
175lr
air press
35 both right sides
24 lf
25 lr

I have to run the springs in the rear that way casue my casrs are always tight so i have to run the springs that way but yes most people do run them the other way to tighten the car up comming off

You guys have to remmember with no bead locks on the right rear and a soft sidewall tire you NEED to run 35 lbs on the right side yes you do lose a little bite but i would rather lose a little bite then roll tires off the bead

Running lighter springs will tighten the car up i need to losen the car up without giving up the spring rates that iam running

thats why i cant understand why putting a 2 inch offset on the rr tighten the car up NORMALLY it will losen the car up put with this new chassis it tightens the car up going in how can i losen it up going in and still not affect it comming off

having the stiffer spring on the rr will tend to make the car tight on entry.

it also seems the front springs are stiff in relation to the rear. i have a 77 nova with pontiac 350 and run 1000/1100 200/225. 3350 total weight

IT SOUNDS TO ME THAT WHO EVER BUILT THE CAR BUILT IT WITH ALOT OF WEDGE IN THE CHASSIS... IN WITCH WOULD PUT YOUR CROSS % WAY UP WITH OUT ANY STAGGEG ..

I BUILT MY CAR WITH WEDGE IN THE CHASSIS AND RUN 255 R60/15 ON ALL 4 CORNERS
SPRINGS ARE
LF-1100
RF-1300
LR-300
RR-250
MY % ARE LEFT 54%, REAR 51.1%, AND CROSS IS 50.7% CAR WEIGHT IS 3230 AND MUST WEIGH 3200. CAR RUNS LIKE IT`S ON RAILS, BUT IM A ROOKIE SO THIS CAR IS THE ONLY ONE I HAVE RAN AND MAY BE TO TIGHT FOR AOMEONE ELSE..

Hey 20bmw, that is the exact same spring setup I have in my '82 Malibu and it works great for me.

Swaping the front springs (lighter spring on the RF) will loosen the car on entry, and have little or no effect on exit. If you pull the RF in with offset it should help the car turn more in the mid corner, but may cause just a bit of push on entry. The combonation of both may be just what you need, but I'd try the springs first.
