warped front rotors, cheap upgrade alternatives?
 

I have a 2001 F4i andafter 5 track dayson itmy front rotors seem to have warped, when braking at speed my front tends to shake.
so since i will be changing them, what are some cheap alternatives? i mean which other brand\model stock rotors will fit with out modification and with out changing the calipers?

I know i can get cheap one's on ebay from a newer F4i, but i figured if im changing them, might as well upgrade alittle if possible.

you sure they are warped? offset suspension will also do the same.

Im pretty sure its the rotors, When on the track brakingHARD i get front chatter, it feels like im drilling an impact drill into the ground.
Now when im on the highway i did a test and pressed the brake lever lightly and there was the uneven rotor chatter feel, and the stronger i press the brake the more apperent it is.

If this is not the brake rotors then i have no idea what else it could be. I have a new set of Carbon Lorain SBK3 brake pads on it.

What do you mean by offset suspension? I had my suspension set for my weight about 5 month ago by a reputable shop.

a cheap alternative is difficult to find. i think a direct swap is a more feasible solution.
did you check out the wheel for dents or alignment?
also, some other guy on here had a problem like this and he thought it was the rotors as well. it turned out he had a loose nut in the fornt end. I believe it was the nut in the tree.

Severe suspension problems can feel like that too. I had ita little. I reduced some compression and took out a touch of rebound. Feels like the tire is skipping, right?

oh you gots the chatter at hard brake eh? i used to have that when i brake extremely hard...was my suspension.

I have the same problem that I think you're talking about. When I brake hard it makes a loud noise sometimes and my brake lever shakes. Also when I brake really hard like emergency braking, you know what it sounds like when you down shift, the clunking, well my bike does that really really really fast like a machine gun. I think it's trying to down shift and it does it whether I have the clutch in or not. How do I know if it's my suspension?
