Lowdown on suspension, wheels and tires

[khronus79]

Well guys, I've decided to buy a new project car and chose the 1st gen as my starting point. I have read countless of threads on the SA/FB but none of the touch on the subject that I'm looking for.
First of let me say that I have yet to buy the car, but that is only a phone call away. I'm a member of various rotary clubs and attend MANY rotary specific events, I live in FL and 1st gens are plentiful so finding a car would be quite easy.
I would like this car mostly for show duty but also for some occasional road race/auto x fun, the look I'm going for is the flush/stance look, it looks amazing on other old school rides but I have yet to see a Rx7 pull off this look, so I thought I'd give it a try.
Here's what I'm looking for:










So here are the questions:

1. Suspension.
-What suspension options are out there to lower a 1st gen???
-Are there any coilovers made for this chassis??? and if so, how low do they go???
-What other modifications can I do to "slam" the car???

2. Wheels.
-What is the widest wheel you can put under the stock fender???
-What is the maximum backspace possible before making any contact with any suspension part???

3. Tires.
-What is the the widest tire one can put on a 1st gen, front and back???
