Hey all as the title suggests I am hoping for for some advice/guidance or even better a step by step guide of how to perform the instalation of m4 convertible seats into an e46 m3 convertible. I know there is an old thread on here but the old link does not work and no definitely ate information. Have the chance to pick up a nice set log m4 seats. Was thinking might be a nice upgrade. Any helping info or someone who can do it would be great. Cheers in advance all.
