Yeah the Veilside kits are very nice

The Supra looks perfect without one but personally I like bodykits

Nothing too too outrageous but a nice kit like the Veilside you said, TRD widebody, Bomex front end, Top Secret front end, those are just some off the top of my head. As for rear bumpers, the Trial rear bumper is awesome! It's got a rear diffuser on the bottom that looks pure JGTC style
