okay as the newbie to this forum and racing in general .. I am cornfuzed.. but hey thats normal..

but as far as rim diameter changes as stated before as long as you dont change the rim width there is no real difference other than maybe a little weight. and added cooling to your brakes .. the difference comes in when you make your tire selection.
I could get real indepth with all this if I break out the books I used to run a tire /wheel store many moons ago..I forgot most of what I used to know

other than that my actual question is on my 87 prelude what wheel options do I have to work with by current rules? it has stock 14x6 aluminums on it now 195/60/14
