I am considering a full GSR swap for my civic in the near future. What changes should i be ready for the first time i autocross after the swap is finished? I am unsure of the weight differences of the D15 and the B18. I am probably gonna swap over the LCA's, sway bars, and suspension from the integra, but it will come later.

How competitive can i be in SM2 with this swap and a stock suspension setup?

Thanks for the help,

Michael
