That sounds like it could work with the FC stuff. IIRC the FC 4 bolt pattern is the same as the GSLSE stuff you got from me.

The only catch I can see would be the length of the steering arms compared to the control arms, you could end up with some wicked bump steer.

If you end up looking at a full tube front, my frame rack will be empty in a few weeks. I spent the day blasting my front clip prepping it for attaching it to the back half.

I see. That chassis is not in the best shape to keep in fully stock. Sometimes it takes 2 cars to make 1 good one

I agree, the FC stuff *could* be an option. Since the Rx2 uses a separate crossmember to mount the engine narrowing the FC subframe will not jack up your engine mounting but should still clear the sides of the motor when narrower.

Another thought would be to use the Rx2 crosmember to frame rail mounting locations then use the FC lower control arm mounting locations and build a tube structure to handle both aspects.

The last issue I see is that the FC struts are super short compared to the Rx2 parts. (I can actually get a measurement later today between the two) This is going to severely lower the car at static ride height. You will need to sort this part out.

Shoot for the inner pivots of the steering tie rods to be the same as the center to center of the lower control arm inner pivots and you will be close. If any bump steer exist then it will be low enough to adjust at the outer tie rod (as long as you plan for adjustment there)

Sounds like an offer you can't pass up
