We always recommend to install NISMO parts. Because Nismo, is a division of Nissan Motorsports & Customizing focused in motorsport and performance-oriented car models for Nissan and also produce best quality parts for Nissan JDM cars. So, Nismo clusters for GT-R R34, GT,  GT-T ER34, Silvia S15  / BNR34, ER34, S15 also gives more performance and best looking. And also compare to stock cluster speedometer changes a lot:  

BNR34 stock cluster - 180 KM/H  /   NISMO cluster 320 KM/H 

ER34 stock cluster - 180 KM/H /      NISMO cluster 300 KM/H 

S15 stock cluser - 180 KM/H /          NISMO cluster 280 KM/H    

note* While your car is in Japan, we`ll change the cluster at official Nissan. Nissan gives a certificate about changing cluster.
