I run on 1/4 mi tracks, on a heavy track the power comes out on top. I am just starting out in a Mod and don't have the power the big boys got but not to far off on a 1/4 mi. I think I could do ok on a dry slick track if I could get some bite. I have a harris copy 3 link car. can anyone help. thanks

Increase rear weight to around 60%, I wouldn't go much more than that. Also, if you are just startin out in a modified and your throttle control isn't the best, try going to a 5.43 on dry 1/4 mile tracks. Or, you can add a stiffer throttle spring, too. Take a little timing out of the car, try running around 24 total advance, that helps alot on dry tracks. Also on a 2 or 3-link, stagger the rear springs. Put the left rear in front of the axle and the right rear behind. Soften rear shocks as much as possible. I run custom valved shocks from AFCO when the track dries out. I run a 91-2 on the left rear and a 92-1 on the right rear. Also, you can soften the extension on the right front to make the car tighter coming off the turns. I also run the custom valved shocks on the front when the track dries out. 77-1 on the front and a 76-2 on the left front. When the track goes dry for good, during the summer months, soften the springs up all the way around and this will help, too. Just my two cents. Hope this helps you out.
