A friend of mine has a 07 G35S Sedan 6spd with RAS. Car is used for drag strip. Hard launches have messed up the subframe. Since the car has RAS only subframes from cars with that option will fit. We have tried over and over to find a subframe that fits.

What is required to delete RAS? From my understanding RAS alters the toe of the rear wheels by using an electrical actuator that bolts to the subframe and pivots the rear spring cup\arm.

I am guessing he will need subframe, spring cups\toe arms, and maybe camber arms from any car without RAS?

 

Assuming the chassis are identical, then I'd just look through one of the online IPB's to see what is different. Hopefully, it is as limited as your guess, and it does not include control arms and such too.
