JDM Speed Cut removal

[wagonist]

I'm after people's tips on how they did this?
What products did they use?
What were the pros/cons of these?

I used a apexi rsm.
No problems
No issues


and because it captures higest speed , 1/4 mile. 0-100 etc its good for a few things. Testing the result of modifications was fun.
I used a early model so it cost bugger all as well. Just hid it out of the way until i wanted/needed it.
