HI,
I ordered recently a kf2 to have something different in my country (Turkey) I won't have any local support at least for a while so should stock some spares to end up the races. I race only 13.5t superstock on a tight indoor carpet track with medium grip level.
-My budget is limited so I should buy as few as possible spare parts. I assume Wishbones, hubs (don't know ıf I would need all 3 of them ?) rod ends are must have. What about front shock shafts, hinge pins, front bulkhead , belt or any other parts ?
-For setup I will order 5 degree yokes and some springs but don't know which springs should I have for my conditions described above . I'm totally unfamiliar with the car and brand

Tony Newland and others on this list have recommended getting some spare front and rear hub carriers (U4380 and U4036) but I have not broken either personally. There is some discussion about parts durability on the previous "KF" thread on this board that you may want to go through. It has a wealth of information and experiences from others that should also help you a lot.
You are racing on medium (to high?) grip carpet so you may end up wanting to fine tune the gear diff in your car with a spectrum of silicone oils ranging from maybe 1k (in cst) on the low end to 12.5k (kit) or even higher on the high end (50k). Higher viscosity will make the car push more entering turns. Given your surface I am betting that you will end up between 3k and 7k but that assumes a lot. CoreRC silicone oils are good quality and are used by the team drivers for this purpose.
For further tuning purposes I would also recommend getting a set of the metal shims that are used to adjust some of the suspension link positions (U4314). Lastly, the aluminum upper trans housing (U4616) will allow you to mount the shocks on the back of the rear wishbones. This is a really nice option for moving some additional weight to the rear.
A great resource for starting out is the collection of setup sheets at PetitRC.com
petitrc.com/setup/schumacher/setupcougarkf
Go through them and find a track that seems close to the track you will be running at and use the setup as a starting point.
I am not sure if they ship internationally or if you already have a good source for parts but DiscountRCStore.com is the best place I know of to get Schumacher parts quickly and correctly and good prices.
I hope this all helps. Let us know how it goes as you get things together.

If you have been following this thread recently you may have noticed that there are quite a few people shearing the front axles on relatively minor collisions. This happened to me. This may or may not be due to a bad batch of parts (over-hardened and therefore brittle) as some have speculated. The part number for these is U4382 and they come in pairs.

My car in stock with the alumnus chassis can barely clear any jumps. Have a 72?tooth spur, and have tried from a 25-34 toothinion. Nothing really helps. Going to throw in a 13.5 to see if I can get gearing that will make it move. They finally tilled, resurfaced, and changed our home track which should bring up the grip which was Non-existent. May try the car again, but feel without the alloy diff uprights car is a lost cause.

Don't like to upgrade cars before trying factory setups first but will look for u4616 too

He is using the kit upright with shims/spacers to get the tower further back. I runs his setup from IRCR, and is working pretty good. Try it out.

I have a question about the rear shocks, i see you can run them mounted in front of the arm or on the back of the arm and i was wondering what does this change as far as handling. Also i am going to run medium grip clay track what way should i run them?

Zero acceleration in stock. I've been trading messages back and forth with Tony Newland and have his setup on the car now. There is just zero whoomp with this thing. I threw in a 13.5 and geared it 72/27. Still dog slow. Checked punch control on speedo, is at 9 running a 100c Lipo. Running low traction chassis setup, ball diff, shocks rear. Tracks I frequent are high to super high bite clay tracks. Last thing I am going to try before selling it is cvds and junking the universals. I know it's not the slipper cause that's locked. Motor is a Shurr speed 17.5 that's is balls out ballistic in my other two buggies.

Did you re calibrate your esc? Lol
The car is fast period. Sounds like you have issues some where else. How tight is your belt?
