well the brands right there au technni theyre 52MM i.e 2 1/16

 

never heard of them, thats why i asked. where are these available from? and do they come in 60mm?

 

I am looking at getting the Defi Link Series. The gauges I think I am going to get is; Boost, EGT, Oil Press. I have been told a while back that the best gauges to get are mechanical and not electrical because they are more accurate. If this is so should I look at some other gauges besides the Defi gauges, or are the Defi pretty much the best I can get?

 

Defi BF
