Default Upgrades past, present and future 99 F4

I bought my 99 F4 about 18 months ago. The main purpose of this bike is for stunts... I'm looking at doing some upgrades/mods this winter, but I'm also having twins around Thanksgiving, so I need to make my money count .


Here's my current mods:

GPR Stabilizer
520 conversion, +14 rear sprocket, stock front Quadra-X Ring chain
galfer steel braided front lines
galfer rear wave rotor
Rear hand brake with shorty clutch cap
Sick Innovations cage
custom 12 bar
Barnett kevlar race clutch

Here's what I want to do with it this coming winter:
Front suspension upgrade
Stage 1 Jet kit (Is this the biggest you can get for this year??)
K&N Filter
clip-ons
New front brakes
Brembo Radial front master cylinder

Here's where my questions start:
What kind of brakes can I get that are better than stock, but don't cost $500? I've looked at both EBC and Galfer wave rotors, but that's a bit of money to put into a stunt bike...

And I've decided on Racetech for suspension, but I'm not a suspension guy, what is a good spring rate? DO I need a valve kit?

In the perfect world I would like to have front forks that can be stiff enough to bring my endos up nicely, but still be fun for the twisties on the weekend. I'm in Japan right now, and we're not allowed to have two bikes, so I'm stuck with one doing double duty until I get back to the states...

Any advice would help...

the stage 1 kit is the only one that doesnt involve modifications to the carbs.

HH sintered pads, I run EBC myself.

Yeah, I have EBC HH Sintered front and rear.

One question on those - the squeak a lot, and give me a lot of grab until they're warmed up, I was told that is normal, but I wanted a second opinion... Only the front give me these problems. This could also be due to the stock rotors I think...

squeak alot when? Normally only time I have brake squeak is when they are rode too much when not needed or got hot.

I have stock rotors on my bike n they dont squeak lol
