setting up a trx90 for racing...sug?

[crazy1]

O.K....My nephew has started racing his trx90 this year,so I have a few ?'s to ask.
1.is there a jet kit for these
2.what can we do or should do for the susp.
3.wheel spacers,a-arms
4.gearing?
5.should the front end be wider than the rear?(spacers?)
and any others that I might have missed.
We already have front and rear wheels and tires.Kinda small budget,so go easy...lol Once we get him going we will go after some sponsors. Thanks for your time and any suggestions.

I tried everywhere for a jet kit and it's not available yet. So I just went to the dealer and got a few jets.
