I spoke with speelingerie in this regard..negligible restriction at worst...No issues for the track according to them

 

No Question...about the restriction issue with many "bra's". Inevitably, all my clients run into overheating problems at the track with they try to run "hard" with the brasiere in place. We install stainless mesh screening and protective films for the Gt3's we service for track useage. My guys run VERY hard/competitively! havefunremainbra'lessdriveporsche-Mark

 

Thanks for the tip.

 

Thanks Chris and aracerx for your follow up.

Makes sense, on the track you need all the cooling you can get, especially on those summer days down at Summit Point.

 

Erik at Cargraphics estimated the cost for grilles at $250, who knows. I guess we won't know until he finally gets them. The screens would protect against leafs, rocks and BIRDS. I caught a bird last summer at Summit Point.

 

I ordered a mesh grill from Gert at Carnewal . . . I let you know how it works out.

edit: got it today along with two sets of pedals (Wow, only two days from Europe!)

Looks like good quality - I put it on and take some pictures.
