I've got the MT90 in my car and love it. I mainly got it for the winter cause it was a pain in the but to shift when the car was really cold without it.
However one of my friends bought the Amsoil which I drove and I couldn't tell the difference. I think either one you get you'll be happy...
Yes it comes with instructions and It's really easy, it only took me 30 minutes to install (after I had the correct wrench). Just make sure you have all the tools they list in the instructions before you start. I thought I had all of them but couldn't find the correct wrench so I had to drive...
Yeah the samething happened to me about 3 weeks ago and they had to replace the button on my door and an antenna. The only thing that really sucked about this repair is they didn't have the part in and had to order it from Canada, so I was out of my car for a week.
I've got that noise after I left my car cool down and then turn it off, it rattles and then squeaks. It almost sounds like the turbo doesn't have any oil on it.
You should be fine if they are on the stock rim. I have a set of 225/45/18 on my stock rims and had 3 guys in the back so the wheel was inside the wheel well and it didn't rub at all the whole way down to Chicago.
I've got 225/45/18 Pireli Snowsports on my car right now and I'm glad I got the 45's on cause the potholes in Wisconsin right now are really bad. I couldn't imagine running any smaller of a sidewall right now.
