Rear Gear HELP

[Zachalanche]

Perfect, as I am starting on the rear suspension soon and I'm going to need to make some decisions. I'm looking at using a 4.11:1 or a 3.91:1 rear gears and a 26" or a 27" tall rear tire. If you can show me this combination of these 4 options than I can get an idea what will work best for Autocross and also for cruising at highway speed because I've got to be able to drive this car to the races and then back again and in most cases thats going to be a long drive.



The information you need is below in red;

Dyno was done at local shop and will be raced at seal level same as dyno sheet shows
*please note that the dyno sheet stops at 6,800 and that I should be slightly higher with a fine tune and a bit more RPM, closer to 500+hp @7,500
