Well i am getting to the stage in my Rx3 where i need to figure out what gears to run in my 9 inch ford. I mostly only race 1/8 mile and a bit of 1/4, i am also going to be racing it in autocross. It has been suggested that i runn 4.88's but i am thinking of running around a 5.67 or higher. With that at 10,000 rpm i will have a top speed of 145 miles an hour on stock sizes tire, which i would probly run bigger taller tires. What i am now wondering is if anyone is running anything with gears that high. If so do you have any links or sumthing that i could find out more about that high of gears with rotaries, thanks, mike
