Not all wheels require caliper clearance, but you should pull a wheel off your car and see where the caliper sits in relation to the wheel mounting surface so you know before buying anything.

American Racing has straight spoke wheels, but not near as common as the D wheels. https://www.americanracing.com/american-racing-vintage-tt-o

Also ET makes straight 5 spoke mags, but they do cost more than the American Wheels.
