Dear Eugine,
As told by president the R33 GTR shocks are suitable for ER34 GTT but can you take a photo and upload here so that i can identify for you because i have changed my suspension also... at least i knew if it is suitable for us GTT or not.
The front shocks is with bushes and rear shocks is with U sockets to connect to the lower arm.
cheers,
Benny
