Most people go with a rear ration broadly between 2.7 and 3.6

The 2.7 end of the range is better suited for cruising, the 3.6 end for spirited driving where throttle control has to be used to stop the smoke.

The most common ratios used sit between 3 and 3.6

To get the ideal ratio you need to know the power curves from the engine, the box ratios and the type of driving you'll be mostly doing.

Most BDR's seem to come with a ~3.1 rear, although I have heard of different ratios, just can't remember the numbers (??3.05??)

As to options - pass. rollbar is 1 I always suggest. Drivers seat slider is another. Dual fans if you are in a hotter part of the country.

PS "Don't plan on going to the track" - it WILL happen. There will be a track day near you and you will go and you'll love it. It's not so much the racing but the people you meet.
