STS does remote-rear mount systems, and currently do not offer any systems for BMW's. I've been trying to get STS to get us a kit to play with and see what we can come up with for a kit, I am toying with doing this project to another BMW we have in house here in the future. We are also currently about to build an E36 M3 with an M52 powerplant, pushing for 600-700whp, but we will be going further than just a HG and headstuds, this will be a full bottom end to top end build. Ill post a link for you to follow once we start gaining speed on the project. your more than welcome to visit the shop at anytime to check things out. We also have an 04 M3 currently pushing over 780Whp and looking for more! Keep posted! And good luck with your project!
