Chassis engineering has closed.
That’s too bad, I’ve found their products to be top notch. Good, fast service too.
I’ve been looking into ifs also. I like the kits from Full Tilt and Street Rod Engineering. They look to be about as heavy duty as it gets, not terribly priced either.
If you want an economy kit, CPP looks to have pretty good deals and lots of options. The JW rod garage look to be good quality and good price too.
