What do you mean what else is a direct replacement, brand or car?
The GTA struts arent shared with any other car, They use the 25/Espace front fitment where they screw in, but they are much shorter with a completely different spring mount.
Brand wise, Konis are a direct replacement, other than taking the cup off your old shocks and fitting them to the Konis. My coil over kit comes as a complete system with new cups etc...
