For the first time I just installed one on my 27. Haven't hit the street yet but I have read so much positive about them that I figured it couldn't hurt. Never really had a problem with the car before but I've bumped up the HP a bit and plan on racing it at some events like the Billetproof drags, and just want as much stability as I could get when the tach is pegged.
Not sure how you could do it with R and P steering though. Not much tie rod sticking out there to fasten one to. I got mine from SoCal and here is how it mounts on mine, which is typical.
