It will help "a little", and the install is a total pain in the ass. The biggest problem is getting the old bushing material out of the shells in the subframe. I used a combination of grinding and burning them out. Still took me an entire day.
Getting the new bushings in is easy, once all that crap is out of there.
The shop that works on mine told me not to bother with the IRS bushings. They said the differential bushings are the ones to replace for wheelhop. Was much cheaper also as the labor was only an hour or two.
your looking at an all day project bro....It took me all day.....word of advice get a dremel tool with a sander or a really hard wire brush to get the old one out.....I had to use a long file and screwdrivers to pry at it.....I did like the more on center feel after installation though....It's not really drastic like they advertise though....I did notice a better feel on the lauch the most though which was cool
