Coach
TO lessen body roll I did the following in the following order. (I learned it all on this web site).
1- Changed the spring load to 3 in the front and 4 in the back. I know that it is a pain to change. But, that is the cheapest, best thing that I have done. (I had seen your posting asking about changing the loading)
2- Widened the stance...Some like the spacers like "Beast" above. Some like the wider wheels. I Went with the ITP C Series, Type 7 wheels. Two sets of spacers were about the price of two wheels. So I opted for a little bling.
3- Change the tires. I went with the Big horn radial tires.
Good luck on the changes. DGR
