OK.. home from work.
What I did= Moved rear shock tower to the front side of the bukhead, and then mounted the shocks on the front of the arms.
What needed to be modified= Bulkhead radius needed to shaved flat, arms needed to be drilled in front, same as outside hole, then mount your BK brackets that are now laying in your pit box to achive the desireable geometry.
What did it do to the car= well.. how should I put this. It made it FAST, it made it smooth and it made it consistant.
I have been working with this car since the beginning of december with less than perfect results.. lately, I have been trying just off the wall stuff to get it to go fast. I have tried dropped spindles (shaved .050")in the front to cause the car to roll more.. which I actually liked.. but it made the spindle very very fragile. I have been running the rear roll center in full high position and i think this is the way to go. My thoughs are running the front high causes the rear end to do all of the steering.. not the front. Personally, I want my front end to do all the work and have the rear end follow.
This past weekend i was staring at my car during down time just dreaming up different ideas and changes. This one, we have seen on another car or two and i went for it.
WHY? why not? took 20 min to rig up... and its another tuning option. You move your shocks out on the arms and you get a different feel.. same principle except the shock is moving closer to centerline.
Results? Well.. i have VERY limmited experience with this setup, and ONLY on carpet... but the weekend before.. my best qualifying time at CEFX (i believe) was a 31/5:00.. and TQ was a 32/5:03 or 04- layed down by a recent Snowbird A main finalist. This week.. my TQ was a 33/5:08.. and then i ran an 06' in the main. This was the SINGLE thing I changed from last weekend to this one. The track was the same, because the same guys were turning the same fast laps and qualified very close to last week. this was a grooved track.. id say if Novak or vegas was a 10 on traction.. and fresh track is a zero.. this track was a 6 by the mains.
Feel? well.. my car has never felt "there". It always seemed to just plow around the track.. never actually feeling hooked up and fast at the same time.. definately would not turn the same lap 2X's. This week.. the car TURNED.. yet it never broke traction. The car rolled through turns precisely and seemed to actually carry speed. The car did exactly what i wanted.. and was never a handfull. It was dare i say as fast as my _______ (insert last car name here). It made the car react faster both off and on power without making it feel over worked.
So= if you guys are bored...try it. let me know what you think.
