loved the old DR30's especially like this....why cant we run this sort of kit
Not sure why it open guards aren't allowed, it sure would make heat management at lot easier!
When the Sport Sedans combined with the GT Championship in the early 1980s some cars like Thommo's Merc ran open guards (I suppose he was logged as a Sport Sedan back then, not a GT car?).
I know the rules did at some point change in regards to the shaping of guards, as the cars in the 1980s had more of a sharp wedge look (some of the pics JD Yort posted will illustrate what I mean) compared to the rounded flaring you see these days.
