Lemming Posted August 5, 2020 Share Posted August 5, 2020 Looking to do a few ST5 races with my SPB. I've looked through the online compliance records and see that some racers are taking the BTM aero (+0.4), is that legit? Quote Link to comment Share on other sites More sharing options...
National Staff Greg G. Posted August 8, 2020 National Staff Share Posted August 8, 2020 The rear spoiler would have to be disabled in the down position. I don’t know the SPB rules and what other mods they allow. I don’t have any in my region in TT5. But if it isn’t Base Trim model or on the list if permitted mods under BTM, it doesn’t qualify. Also cannot have a rear wing or air dam (or rear diffuser for ant ST5) Quote Link to comment Share on other sites More sharing options...
