Never had a pro driver give me an opinion of the handling. I can tell you that with new koni shocks and lighter springs, handles better on the bumpy
streets in San Francisco. It is tighter than my Shell Valley Daytona Coupe and my '88 lowered BMW M6.
However, with that said, I would think that a Kirkham, SPF, ERA, and FFR having more cobras on the street/track, would have tweaked and optimized their suspensions.
Billet is great for shows, but not necessarily better for racing. How many race cars have billet suspensions? It's the design, angles, unsprung weight and testing. I'm not an engineer, but just my $0.02 (I spent $$$ tweaking the shocks and spring rate, and there are less than a dozen CER's out there)
Ever see John's JBL suspension? All business, very nice.
Yes, Cutting Edge Replicas is in Manteca, but I believe they have stopped production. I broke a brake caliper bracket a few months ago and they sent me another one in a week.
Long story short, didn't spin out on the track (probably driving too slow), had a good time, so it handles fine.
Chris (Boss429?) also has a CER with a newer suspension, in central CA.
