The US BMW CR cars that convert to true rear coilovers have issues with those mounts mushrooming out the top, but they also run really really high spring rates. I can't find a direct linkable picture, but if you go to http://www.tcdesignfab.com/, look at the projects page at the E36. There is a picture in there of the reinforced rear shock towers. I think the rally car build on here shows the same. |
Thanks for your advice ,we run a 275lbs rear spring with no problems (yet) i am keeping a close eye on this and will post any problems.
