Jim -
I have the first production FIA kit that ERA built - I cannot say enough good things about these guys - they are an extremely dedicated bunch.
There are other some other good kits on the market, but you will find NONE better than the ERA. The body is absolutely faithful to the original FIA car - it is NOT like some of the others brands, where they merely trimmed 427 fenders to try to replicate the 289 FIA shape - this car is dead accurate.
The kit supplied by ERA is very complete, and everything fits together - no surprises. The car goes together very well, and their assembly manual is second to none. The parts are delivered on time, and, if you have any issues, they are handled expeditiously.
I have had my car on the road for 5 years, and enjoyed every minute of it. The ride of the car is amazingly smooth and supple for the level of cornering force it will generate. I have had it on the track at a number of SAAC events, and it is very predictable in the corners. I feel it combines the best of both worlds - the downright sex appeal of the slender, lithe 289 FIA body style, and the handling characteristics of the updated (coil-over spring-suspension) chassis.
The guys at ERA were great to deal with, and have exhibited "after-the-sale" support that any manufacturer would be envious of.
You can't go wrong with an ERA - and the 289 FIA is a terriffic car!
regards,
Jeff Burgy
