I would like to purchase a short shifter for my 93 dx. anyone have any experience with these? if so are they easy to install? what's a good brand? and does it reduce throw by 40% like it says it does?

 

I helped my buddy install one on his EX. It wasn't that hard to install if you have a bit of DIY experience. I think it was a Solo or something like that. Just make sure you don't make the same mistake he did. He bought an aluminum shifter first time around and snapped it off. This Solo was solid steel and a lot stronger.
I tried it out after the install and it was kewl.
