brake balance issues
 

anyone have a brake balance issue?? car pulling fro left to right when ever it feels...Nissan told me its common with the sport pak...couldn't deal with it so BBK upgrade and still doing it?? any help would be great!!

Your description is a little confusing. I assume you mean under braking the front of the car is twitching side to side. If this is the case check your front toe settings. Mine were off from the factory and under hard braking the car was twitching horribly. Got the setting back to zero and the problem is gone.

If I understand you correctly (not easy), it sounds like you upgraded from the sport pkg brakes to full BBK brake pkg for something that an alignment would have fixed :ugh2:

Wide tires suffer from what is known as tramlining. Even just driving straight down the road you can often feel this effect, but it is worse under braking due to the increased weight transfer to the front.

Zeroing out the toe in front will help reduce it significantly, but you can't eliminate it 100% when the front and rear track is slightly different.

yah, definitely zero toe to start if one's running wider than stock stance up front and noticing tramlining.

also running softer sidewall tires like DW's will help reduce the effect.

dang guys my engine is running a bit ruff lately, it even threw a code... guess i better get that new GTM TT kit!

jk OP, good luck w it.
