Hey guys I am about to pull the trigger on the wife's christmas gift to me. I am looking at BMR for the rear end. I would like to get lower control arms and relocation brackets and then the upper control arm and mount. This car is not a daily driver and I'd like to aim for a road coarse set up, although I'd take it to the local drag a few times a year as well. I am looking at the boxed fixed lenght lca's with poly/spherical and then the adjustable uca. I'm not sure if I want the spherical or poly upper. If I get the spherical do I want their bushing EN-1, they say that it helps with launching. I don't know if that would help with handling. Thanks for any info guys... Shawn
