I am new to this site, therefore I apologize if this topic has been covered before. I have a Modena on order. It is due to be built in March and delivered in late April. I ordered a rear challenge grille, partially for appearance but mostly to reduce temperature in the engine bay. I have heard of challenge grilles warping on 355s, and I have noticed virtually all 360 challenge grilles have small dents or at least irregularity in the vicinity of the corners of the engine cover. In reading threads on this site, it seems that most prefer 360s in their natural state, without the challenge grille. Is this just a matter of aesthetics and personal preferences, or is there a good reason to avoid the rear challenge grille? Secondly, I ordered the racing seats, not because my car will spend its life on the track, but because I found the conventional seats quite uncomfortable in the mid to upper back area. I consider myself to be a normal or slightly larger than normal size six-foot guy. Does anyone else feel the same way about the regular seats?
