I'll throw in my two wooden nickels. There's a reason the GTM kit is only 20 some grand, and Fran's is around 40k for the deluxe. I went and almost bought a "80%" complete GTM up in WA, and the kit needed much work to say it modestly. It wasn't even near 80%. The kit did have some decent six pot Wilwoods fr and rear, but had chinese Gen V Z06 wheels and ultra crap tires, like not even a brand name. Body wasn't aligned, need a thorough sanding to get rid of the molding edges, paint, CV axles were rusted it had been sitting so long, tube steel frame, etc.
Fran gives you a car with essentially a paint job, aligned body, pushrod suspension with quality QA1 stuff. Aluminum frame, radiators, he helps you find a motor, transaxle, has the hook ups, and overall I think the SL-C is better engineered. You get many parts from him on the car you would otherwise have to scavange from a C5/C6 for the GTM.
The final build on a FFR is a calculated 350+ hours, and Fran's stuff is a theoretical 200. At a $100 per hour labor charge at any shop that would come out to $15,000 plus the parts, so Fran's car is an equal if not better buy.
Support from RCR is much better. I've emailed and called FFR and they are slow to get back, where Fran can almost always spare a minute.
