S13 4->5 lug conv. Worth it??

[SR240SXT]

Hey guys, im getting an s13 soon, and im wondering if its even nessasary or worth it to do the 4->5 lug conversion. My goals for the s13 is basically to make it my little race car, for autocross, drift, and such. It will be pushed hard basically.

I know the wheels im getting, and they are offered in the 4x100 size. I know i will be getting coilovers of some sort (tein prob, i duno what much this has to do with the conv. though, lol) and i dont know about the brakes yet. I guess thats the only thing that leads me to this conversion. Are their any brakes available for the 4-lug? Anyone mod there suspension/handeling/braking and ketp the 4 lug?

What are your guys thoughts on this? Shoud i just go ahead and count on having to do this? I need to be sure before i order the wheels and stuff obviously.

Also, what other advantages am i going to get by doing this? Disadvantages to keeping the 4 lug?

Thanks!
