The MR2 has no vents in the inner fender well to remove pressure build up behind the fender. "So what" you say, "There are plenty of places for the air to exit the front bumper and from behind the fender." Sure, the air will eventually find its way out but by the time it does it has already smacked the inner fender and begun lifting the nose of your car. You'll notice this as a "light" feeling in the steering at high speeds. This is no good.

How do you solve the problem? Simple, just cut a vent in your inner fender well. I used a Dremel tool with a cutting bit and made a 7" x 2.5" rectangular hole in the inner fender well just in front of the tire. You don't even have to remove the tires. Just turn them until the steering wheel locks one way. This will make enough room for you to cut the vent. Then all you have to do is turn the wheel the other way and do the other side.

I did this simple procedure to my MR2 which has an extremely light front end due to weight reduction. At speeds above 100mph the front end would get the inevitable "light" feeling. My stiffer springs only made the problem worse. Normally, the MR2 makes use of its flat bottom to create a small amount of downforce. However, after stiffer springs were installed there was no longer enough downforce being created on the front end to overcome the pressure build up behind the inner fender and within the front bumper. The reason being that the springs were pushing up harder than the air was pushing down.

After cutting the vent I went out and tested it. Surprise, it worked. The car felt much better at 110mph. It felt very steady and not nearly as light as it used to. This, of course, improved steering feel as well.

Overall, a simple and worthwhile mod. You can't really go wrong with this one.
