wheel question

[180sx]

What do you guys think about wheels for our cars? size, style etc

I got 17's and they feel much better than oem stuff of course. And recently i have been looking to get a new set. Need new tires and rims came with the car so why not if the price is right. How do 18's sit and feel are they worth while getting?, or 17's is best option. I know the back is fine but in the front with the spring seat with the car 2.5" lowered and usses tokico blues whats the widest rim that fits safely in 18's?

And i know its a sports car an all and some volks or other 15 pound wheels is what most owners would prefer. Myself on the other hand i don't care about extra weight , as long as they look sweet.I don't compete in auto x etc mainly daily drive it and drag here and there. So with 18's i figure i get better traction and handling.And as far as konig and motegi, anyone ever had issues with these wheels?
