So i need to replace my rear sub frame on my em1 the guys at hmotorsonline.com said i could use an ek9 type r rear subframe. Just need an second or third opinion to see if they are compatible since they both use the rear sway bars

 

Should work ok. Just need to get it welded in. Is your stock one torn up or are you just moving to a bigger rear sway bar? If it’s the latter it’s easier to just get a brace from ASR or one like it.

 

I say yes.

 

Yes it works perfectly and you no longer need (or have the option to, actually) a subframe brace to run a large bar
