2010 ninja 250 race prep advice

Hi all i just bought a cheap layed down 2010 ninja 250 which has barely 3k KM

I bought this bike for the sole purpose of making it a dedicated track bike
Some of the things i have ordered are
1. clip ons that attach to the bottom of the triple clamp.
2. rear sets.
3. tank anti slip pads
4. EBC HH brake pads with steel braided brake lines on the front only
5. Metzller Front :-110/70-17, Rear :-150/60-17 (I have'nt put this on yet basically this are my brothers tires which still has some decent thread left on the sides and will use this until they burn out then switch to 140 rears).

Now I need advice on the suspension as i have 0 knowledge on suspension would be a great help to me if someone can point me to a right direction
for reference im 6'3'' and 170lbs.

I also plan to put some extra padding on the seats to make it a bit taller so that my legs are not as cramped if anyone has done this please also advice

Thanks for your time and any input is well appreciated.
full disclosure i havent done any track days yet but i have practiced using my brothers cbr 125 and my duke 690 on parking lots and im able to knee drag.

Would appreciate a budget friendly advice as this is a budget build got this bike for only 900 cad

I haven't upgraded the suspension yet. From what I've read so far, you have the following options for suspension:

First and cheapest, you change the forks oil for something heavier (10wt or 15wt) and change the springs to something stiffer ($120). Check to find a recommendation for your weight and level of riding.

After that you can also install Gold Valve Emulators ($170) which will allow you to tune the forks for high speed compression. To do this you need to take the forks apart.

Another option for the forks is to throw away the stock internals and put cartridges as Ohlins or RaceTech. About $1000.

For the rear, you can go with a Suzuki GSX 600/750/1000 rear shock swap. Get one used off eBay for less than $100 and hopefully then rebuild it and spring it to your weight.
I don't know what year of GSX's will fit. It looks like some will fit but are shorter and lower the rear end. You can compensate by changing the suspension links (dog bones).

Or swap for a more expensive and racing shock like ohlins, penske. I guess about $800. These shouldn't change the height of the bike.

Hopefully someone with more experience will comment on this.

Mods are fun, but make sure you don't spend all your money on mods and then don't have enough to get track time.

When your pace starts to pick up a little bit the kickstand mounting bracket on the frame starts dragging and can toss you down pretty easily. 08-12 track bikes typically have the kickstand mount cut off.

The stock muffler drags pretty easily too.

Used ninja 250 race bikes go for about $1000 allready set up if you can find one.
