If you guys are going for the look, and don't mind the cost, then go for it. If you want a shifter for racing, skip it. Without modification they don't work as smooth as you would want for racing. Truthfully if you get your trans. set up right you shouldn't need to manual shift it anyway.
BUT, they sure do look bitchin'. And the car show comments will make you laugh quite often.
FWIW the set I sold for my buddy brought $650 on this board, with every bracket and plate and cable included. I could have had them for $500 but I passed, and I don't regret it.
hope this helps.
