I bought them from Speed engineering. Unfortunately they appear to have it labeled compatible or universal with the M chassis cars (under the Supra MKV parts page). At the time I figured that was possibly a valid case only to find out its not after trying to install them (Ours is a-lot bigger)...
Me, who ended up buying some for the suspension arms too. Only problem is I ended up buying the ones for a new M2/3/4..
Also too late to return them. Anybody on this forum got a new M car that’s interested in buying these from me?
I test drove a M340i as I’ve considered one as a daily. And all I have to say, Holy Moly! The Supra is way better. The M340i is like a Tesla or Lexus with a B58 & ZF. That’s about all these cars have in common it seems. The suspension is apparently the same but for some reason it feels better...
