Ranger Mike thoughts on stagger We are running a pavement tour type modified. We run a 100 laps on 1/4 and 1/3 oval If I reduce the rear stagger by 1/4 inch instead of 3" it would 2 3/4" and increase cross will that help save the right rear tire for the end?- mikey531

Ranger Mike What is the correlation between torque and horsepower in a pavement modified. This is my theory, you need torque to get you out of the corners, but too much torque may overcome the traction of your tires no matter what you have for a setup. Horsepower keeps you going down the...- mikey531

These are the temps that we got after the race. We did them on the front stretch as we had go there for 3rd place finish..

I will post the tire temps later today. I had thought about an adjustable panhard bar like NASCAR has. Thanks- mikey531

New question, We have been playing with stagger and last night we had 4 inches of stagger. The car was very fast for the first 20 laps then when tight. We were lucky to hang onto third. We knew the tires would grow to more stagger that we have ever run so we lowered the track bar 1/4 inch to...- mikey531

Another idea that kinda worked but not really on our asphalt modified. We tried to reduce the rear weight by moving as much as we could to the center leaving us with a rear percent of 51.2 I want to put about 25 pounds of lead behind the fuel cell and see if I can get the rear up to 52% I think...- mikey531

We do use nitrogen but at some races we have to use their tires and we draw for picking tires well with our luck we seem to always pick last when there is not much to choose from. I was hoping my thought of getting the sway bar back where we had it would work but I guess not. Thanks- mikey531

Yes I am using a stagger tape but we put on at least 2 tires each race and even getting the same chalk mark, unmounted tape size and mounted tape size it is still a guess as to what it will come in at. We set our bar neutral at the shop. I was just looking for an easy way to adjust the car if we...- mikey531

Ranger Mike I have a question. We are trying to duplicate our setup when we put tires on at the track. I try to get the same size etc but never seem to get it right. If we have the car parked in exactly the same spot with the old tires and measure the play in the front sway bar, when we put new...- mikey531

Ranger Mike, We are setting up our Troyer asphalt modified for big 1/3 mile (measured on the inside) flat low grip moderate banking track. Troyer recommends moving rear radius rods to the middle hole to 4 degrees down on both sides. After we square the rear how will that make any difference...- mikey531

Asphalt modified racecar aero tips and ideas
We run an asphalt modified on 1/4 to 1/3 mile tracks. We have been thinking about a trap door in front of the spoiler to allow trapped air behind the rear to exit in front of the spoiler. We have also moved the solid rear panel up the 1/2 " from the rear bumper. We are also using a 1/2" square...- mikey531

I have been using this forum as my setup bible for almost 4 years now. We have been removing weight from our pavement modified, and so far have taken out 74 pounds from the car. We just moved the 22 gallon fuel cell ahead about 2 1/2 inches. We are hoping it will help balance the car or did we...- mikey531

I have a couple of questions about our asphalt modified that we race in the Northeast. We have put the car on a diet and taken off approximately 60 pounds which we will have to add back on. We can have 56% left side. Should we strive for a 50% nose and 50% rear? The other question is coil bind...- mikey531

Has anyone tried using two springs on the front of an asphalt modified? In my simple mind if I wanted a 500 lb spring on right front could I use a 800 and 200? that would give me my 500 rate and the 200 would react quicker than a 500 for weight transfer? I was thinking about doing this to both...- mikey531
