besides being a very heavily modified pro4 the electronics are flipped, new motor mount, looks like a combo of moving servo back and maybe new steering rack position for ackerman adjustment, new steering rack arms, chassis looks longer. shock towers look to be the same height/positions am I missing things?
are the hinge pin blocks still the same geometry? curious what is that extra holw next to the steering rack?
car in that pic looks real nice

I looks great. I hope its more than just the graphite and a few alumimun bits. I see that it doesnt appear to have HB front arms. Rear doesnt look right iether, but its been a year since I sold my Pro 4. Towers also look lower due to the fact your running that Mazda body and nothing is poking through.
If its a conversion kit, donor parts like bulkheads, camber blocks, driveshafts and diffs (basically all the parts that didnt transfer over to the cyclone series and tcx series cars) are almost impossible to find. Strip out one hole in those factory bulkheads and now you've got a shelf queen.
If this is a ground up design thats based loosley on the pro-4, I might seriouly take a look. I was fairly let down by the Pro-5 release and have been waiting for a good shaft drive to come along that didnt cost $500 in the used market.
If Bert mentions the TC4 here, some-one who knows him, please thump him.

Bert has been suspended for a month, hahaha.
Luckily I was able to find a spare bulkhead set from Australia but it did cost me a pretty penny to ship it here to the US. Does anyone know which DCJ's will drop right in a Pro4?

According to MikeR the TCX version fits. And thanks to MikeR for breathing more life into a decade old car! The new chassis looks awesome.
I would like to know also if there is a drop in part because my car chatters big time.

There are a few NIB Hara Pro 4's on eBay right now.
I'd love to have my old Pro 4 back.
If anyone ever sells one, let me know!

For those using DCJ's on the Pro4, are you guys using TCX c-hubs? Are they drop in fit to the Pro 4 arms and maintain the same geometry?
Or are you guys just replacing it with TCX/TCXX suspension arms completely too?

The TCX DCJ's are a drop in fit with the standard Pro4 components e.g. I didn't change anything else.
