i have a set of gsr white face glow gauges given to me but my car is a ls can i use these in my car where my car don't go up to 9000RPM

 

you'd probably have to trim them a bit and they'll also be in-accurate (needle wont point to the right number because the numbers are shifted).

white face guages aren't that expensive, sell those to a gsr owner and buy white faces for your cluster. or you could swap in a gsr cluster and then put those on.

 

true, ya i'll sell them

 

should i change my bulbs back to the oem ones when i goto put in the white face glow gauges? i currently have super white halogen bulbs replacing the ones in my cluster
