Quigs Posted October 19, 2018 Share Posted October 19, 2018 (edited) Rule clarification from the experts please. In the 2019 ST5/ST6 rules under section 6.1.4 "BTM Aero" Modification Factor - line 4 in the exceptions to BTM aero section states the following: 4) Front wing window/frame removal and replacement with Lexan. Normally, I would assume it should be written as "removal and/or replacement" if either were allowed, but the wording implies to me that only replacement with Lexan is the available choice. I'm hoping it is just a typo/oversight as I would very much like to remove the driver side wing window for easier exit in case of emergency once I install a halo seat. There are other areas in that section of the rules where "and/or" was used. This is for a NB Miata BTW. I know wing window removal is fairly common in non-Spec series. Thank you for any insight you might be able to provide! Edited October 19, 2018 by Quigs Quote Link to comment Share on other sites More sharing options...
Quigs Posted October 26, 2018 Author Share Posted October 26, 2018 FYI for anyone that stumbles across from this, the answer I received from Greg is that removal of the front wing windows is allowed. Quote Link to comment Share on other sites More sharing options...
National Staff Greg G. Posted October 29, 2018 National Staff Share Posted October 29, 2018 I'll add the "or" to the rules in the revision coming. Quote Link to comment Share on other sites More sharing options...
