Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
After reading this thread i have decided to leave my car out in the next hail storm to get dimples on it, so it goes faster, however my bikes and my VCM OTR have smooth air intakes and that is how they are staying, despite what the TAFE lecturer sais!!!
You've caught me in a good mood so I will just give you some advice.
I don't like being called a girl, spoilt, arrogant or the suggestion I will wee my pants at something.
I also don't like you pointlessly being negative towards one of the sites sponsors.
So, curb the attitude tiger because next time you may catch me BEFORE my coffee and I won't bother with advice.
Just an FYI, the discussion about golf ball dimples was to explain why the OP's setup will work WELL. It was an arguement in FAVOR of what the OP is done so next time and it's efficiency, read and understand before posting... anything... anywhere.
Cheers.
In short they are cheap effective solution with minimal relative drawback.
