Thank you. A lot I've been thinking, just having trouble putting it into practice. I have some very good ideas to try this springAngle of the ladder bar is only a quick check, assuming every bar is located at the same point on the axle. The car only reacts to how far the pivot point (front bolt) is off the ground. You can change it by car height or bolt location. That's it. That's all there is. The higher the pivot the harder it hits the tire. The softer the spring the harder it hits the tire. More power (converter, engine gear ratio) hits the tire harder. The shock rebound controls the speed of the hit. The compression holds the tire down If it hits the tire to quick the rebound is too loose. If it bounces the car back up the compression is too tight. As for the front the same applies to rebound, compression and spring rate. The only other adjustment in the front is the amount of travel. More helps hit, less the opposite. C/G (weight distribution and height of that weight) keeps it from standing on the bumper. Higher and rearward will load it. Weight in the center is more tunable than at the ends. That's not always possible with a nose heavy car. Radials like to be hit pretty hard. Thus high bar pivot height. Adjusting how hard it hits and the amount of speed that the housing and front end move is the key. Try to slow the front, raise the rear bar and then adjust the rear housing speed with the rear rebound. Watch getting the rear compression to tight. when the side wall releases it'll blow the tires off. Good video is key. I watched my sons turbo car smash a 275 M/T pro so that the rim was within 1" of the pavement. Then rebound to original height. This happened with the car moving forward about 3". Obviously the rebound was WAY to loose. And we haven't even mentioned power management.
To the OP
The track you race at it's not the greatest for radial tires. Thursday nights were your best shot to test there. Any other day you'll chase shock settings and front end travel adjustments.
Gary is on point with ladder bar and shock settings. Very good advice coming from him.
Not sure if we met before. I like to test at Dagrove on Thursday nights whenever possible. Another good track to go test at is at Cordova when they have their small tire race. They have test and tune lane open and the track is on kill for radial tires. I race and test with customers at, Byron, 41, RT66, Cordova and Dagrove.Have we met? I do run at great lakes and try to get there on thursdays when they prep the track more. And I believe in what gary is saying and am currently changing my front crossmember
