What year 240 you got?
I got a 98 & my OBX front strut bar fit perfect. I forget the cost, but it was fairly cheap.
I've also got an OBX rear low tie bar that fit perfect. Again I forgot the exact cost but it fit perfectly as well.
they both made a world of diffrence

I'd givem thumbs up
Tanabe I think has a rear strut bar for the 95-98 models for about 120$ I aint bought one, but might.
