Can anybody help a down under Aussie mod racer? We are required to run leaf spring rears in our cars, with no torsion or anti wrap up arms or devices, and only 1 X shocker per wheel (not coilover). How do I get the car to hook up coming off the turns. We run American Racer tyres, similar to IMCA tyres and have a minimum 2200 pound rule. What effect will lowering blocks have on my leaf rear in relation to forward bite. If anyone can help I certainly would appreciate it. Yours AusBigMac

USE THE LOWERING BLOCKS TO CHANGE YOUR CROSS WEIGHTS. MORE CROSS = MORE BITE

Lowering blocks will help forward bite, they give the axle a leverage affect and wrap up springs more.If you really want to get more left rear bite,preload the left rearspring. ( clamp up left side at 10 degrees neg. pinion then jack up pinion to 6 deg. and clamp right up to hold it there) BUT keep an eye on ride hts this will wear the leafs out faster. Pinion angles are estimates just try what your comfortable with and it will depend how much lowering block you run.

What types of leafs are you running? If you can run the Chryslers instead of Camaroes the locating pin is about 4" farther forward on the Chrysler which helps on less wrap up and gives you better bite. If the front mounts are in stock location try raising them about an inch or so, this will also help on forward bite. I always ran a thicker block on the right rear and it was adjustable front to back to give some trail if I wanted it. Try the AFCO web site, it has some pretty good info on leaf spring settups. Hope this helps.

Thanks guys for your help. We have only run the class in Oz for 4 years, myself 1 X season, and by the answers I got you guys have got the wood over us Aussies. Thanks again, I'll certainly be back picking your brains throughout the season.
