Any advice on choosing racing seats for an 89 E30; this is a D.E. event vehicle only, rarely street driven, budget minded, but decent quality desired. Looked over e bay and have no idea if this stuff is acceptable or not that is sold as new. JDM, Turino, etc.brands. I'd be happy with used, if any leads can be offered. By the way, I know I have to offer the same restraints for an instructor, but does that mean both seats have to be racers?
