This has probably been covered already?...., but thought I’d just add that in our coupe “ Wife and I ” both noticed a difference with the windrestrictor in that wind buffeting greatly reduced with roof stored and windows down, less noise from less wind makes conversation easier or tunes that much clearer....and my favourite the sound and roar of the exhaust/engine. Now to save $$$ for next year’s upgrades...shifter, sound deadner, red mats , Valentine 1 Gen2 .....so much for retirement
