Since your budget is around 2600 so I assume you're getting 18" and tire will probably set you back around 500 (including shipping and etc.). So you have around 2100 left and you probably can get some carlsson 2/5 (looks small b/c of the lip, the 1/5 version looks larger), Brabus VI 1 piece (its a 6 double spoke rim), Moven replica of LM5, and Moven replica of Brabus VI 2 piece version.
The moven is around 850 so you have money left for other mods, such as exhaust or a cupkit.
The Brabus VI 1 piece real deal would cost around 2100
Not sure about Carlsson 2/5, but sometimes you can find some brand new carlsson 2/5 on ebay for 1,300-1,500 and 1/5 for around 900.
Hope this help,
