Martz, Fatman, CA Chassisworks... TOO MANY CHOICES!

[F70t/a]

I'd place the frame options as follows:

C.A.R.S. full race frame
Wayne Due C5 frame (requires engine setback to clear rack)
DSE mod'd stock frame
Wayne Due C4 frame
Martz
Chassis Works
Stock with Guldstrand

Obviously the first 2 options are mucho $$, but well worth it in the end. It seems to me there are those who have the Wayne Due stuff, and those who wish they had it.
I'd recommend the DSE frame to you Doug, as we can do it here in my shop. We already have the jig and experience, so it will be on track with what you are going for.
I can also see no problems with the DSE/WD IRS combo.

Is there a site for C.A.R.S. full race frame?
