I'm already running a good deal of bolt on's, on the stock. if i did a tune it be to protect my engine from kr. On the track on my last session i had a really hard knock. I'm going to chaulk it up to the fact that my fuel tank was empty and fuel pump must have starved for a second.
So far brakes are good i was running Hawk HPS at the track and they worked very well with not fade even though they were smoking, the tires i had worked well also only time i sliped was during the rain session, and even then no to much. I'm still trying to decide on a suspenstion setup, but i know i do need to do that.
