You claim the FFR spec racer as a highly developed cobra, yet don't mention the fact that JBL appears to be clearly setup for track use. No offence to anyone, but does any one else notice how much the JBL looks more like a cross between a cobra replica and a Lotus 7 replica? The FFR might be developed, but the JBL is also pretty damn fixed on having a low c.g. and track-based suspension (less than 1" suspension deflection in braking and acceleration for the series 4!)
Also, how can price NOT play a role in the decision?? It seems to be fairly true that money can make anything faster around a track. The spec racers are $14k kits and are available for about ~25k if you do your own work, or ~35k if you dont.
No affiliations here, I'm just stating my opinion. And before someone gets offended... I'm not trying to ruffle anyone's feathers in any way here... it's all love
