late 80's early 90's sports car preference?

Hello! I have been debating to get a late 80's early 90's budget sports car that i could compete in auto-x with. i barely see any AW11's in any category, i would think they would be going up against miatas and crx's and winning, but is the miata and crx just that much better of an engineered car? with the miata's double a-arm and mass support in Auto-x, why can't the AW11 compete with it? mid-engine in an AW11, i have read toyota engineers who have prepped them for N2 racing that they drive like F3 cars (F1 basically) perhaps auto-x is too constricting, not to bash on a miata, but given more tuning freedom the potential of the aw11 could surpass the miata and crx?

they can be very competative... there is just more aftermarket support for miatas and crx's
