Auto Racing: springrates (2), wheel hub, rally style

Question
Hi Mike, Thanks for the reply,A massive help and a real eye opener. If i understand correct the balance of the car is the important part and to achieve this i use springs /adjustments on all four corners .. The actual poundage of the springs depends on my driving style and circuit conditions. so if i start with a very high rate spring  and balance all four i would end up with a ride like a gokart. the opposite end of the scale if i start with a very soft spring and balance all four corners i would end up with a rally style set up..  if i am correct so far . then for smoothish tarmack oval a good starting point would be a slightly higher rate than a std spring...
On the method of adjusting corner weight i have modified my front strut (mcpherson type) where it fixes to the wheel hub. this gives ne an inch of movement to raise the veihcle.will this have the same effect as spacing the spring for more height..(hope you can understand what im trying to explain) cheers mark


Answer
You got it!  You're a fast learner.  A person wants to go for a heavier spring on the side that does more work, seeing's you folks turn right, you need a heavier left front.  Now, a person wants the other front tire to share the work more so, putting a heavier spring on the left rear will shift your weight in the corners to the tire that otherwise don't do much.
   I have another suggestion.  On your left front I'd siggest using a tire with a stiff sidewall, preferably one with  more cords in the sidewall.  I'd also adjust your camber so the bottom of the tire is a bit out, the top in.  Imagine how the tire sits in the corner (where races are often won and lost).  Having the tires as straight up and down as possible increases your amount of tire contacting the ground.  Here is where using a pyrometer helps to.  Measure right after a race or practice.  Take reading on the very outside of the treadface, in the middle, and the way inside.  If the outside of the tire is hotter, increase camber.  If the middle of the tire is hotter, decrease air pressure.  If Both inside and outside are hotter, increase air pressure.
   Get the picture?  This will maximize the use of your tire.
