I brought my car in to the shop for machining my rotors yesterday and the mechanic pointed out that both front suspension control arm bushing has cracks in them, he mentioned it's normal for street car put to track use. Is it common for all of you to experience this? Are there any nismo or aftermarket substitute for the bushings? My car has 40000 km and have been to the track 4 times plus a few autocrosses.

are you talking about the 2 upper control arm bushings or the one large single lower arm bushing? eventually the worn bushings will begin to effect the efficiency of the cars handling, but for street use it wont really hurt much. all the aftermarket adjustable control arms have new polyurathane bushings in them thatwill last much longer. i havent heard of replacement bushings as of yet. i bet it would call for an upper arm replacement with new bushings loaded before finding aftermarket bushings!
where are you located? i have my factory arms if your interested in them. the bushings have no cracks or stress marks of any kind. they have very low mileage on them since i pulled them out a long time ago to replace them with adjustable units..........

**just to note, if you havet done any mods to void your factory warrenty you can try runnig by your local dealer. if you dont admitt to auto-x you could probably get them replaced under warrenty**

The kinetix arms come with energy suspension bushings. I'm not sure if they will fit the stock arms but it might be something worth looking into.
Buying the 350evo control arms would also solve the problem
