First, head over to the MR-2 webpages for this:
Mine 8) http://www.sandiegocrusaders.com/cars.html
Nathan's Page http://web.mitsi.com/autocross/

More info than you could ever want. P.S. Welcome to MR2s.

Scotty might, not me right now. I am convinced you need to run a 225
tire, and even though I think the Kumho's have a great grip, I don't
want to run with that much less width this year. Now, ask me what tires
I will run? Think "rocks". 8)

I have run both in my 91 MR2. I like both. They each have advantages. I
don't think it matters too much.

Or somewhere in the 75% ST stiffness range. 8) And A.J., if I am in that
group (you forgot a guy on the east coast btw), then you are in the
group.

Yeah, I noticed that too. 8) Just get 4 of the 90105-15006 bolts. New
nuts is a good idea. Then remember you need to really torque them down.
You won't believe me, but later when your camber goes positive in mid
turn, you will remember that I said you REALLY need to torque them
puppies. Mine will probably never move again.
Now I just need to figure out why Andy's car turns in so much quicker
than mine.
