What links do you find to have the most options available for the z31 in reference to wheels/rims? Where can I go on the net find the merchants who have good communication and versatile shipping (worldwide)? As many links as you can think of would just be fine...

my z31 still has stock tires and wheels/rims...225/60 15R...I believe that is what they are...

Excellant links...Thanks...

I'll probably go with the www.victoriatire.com link...

Now most of there selection is 17" tires/wheels...What am I going to look for for sizes? 215/45HR 17 or 235/45HR 17? Should I stick with only 5 lug pattern wheels?

Do I have to make any adjustments to the vehicle to put these on and run fine? What are the advantages/disadvantages to having a larger tire/wheel? What's your opinion on the best quality springs/shocks?

much appreciated...

Unless you buy adaptors, the 5 lug pattern is your only option. There's no point to going with a different lug pattern. Most people try to get as close to stock outside diameter as possible to keep the speedometer from changing much.

Depends on how wide and what the offset is of the new wheels. Get too much offset, and you'll be hitting the strut housing in the front. Then you can buy adaptors or spacers to bring them out. Get too little offset and you run the risk of them rubbing on the fenders when you hit bumps.

For regular everyday use with a slightly better sporty feel, I highly recommend the setup I have on my NA. It is Eibach springs with Tokico blues (non adjustable) shocks. I've had them on that car for about 6 or 7 years now and still love the way it handles. Keep in mind this is NOT a race setup. It's still smooth enough to drive over rough roads with little problems or back pains.
