All this learning is sure a lot of fun!
Well I have been to the track twice now. This is my 1st race car ever and I decided to jump into an IMCA stock car.
When I first scaled the car (before the season) I came out ok:
Total weight: 3110
Then I started playing with the car with the LR weight jack by putting in a couple rounds of wedge and moved my 50# of lead from the right to the left and my cross weight went down??? Go figure. I called it a fluke...I put everything back to baseline and went racing.
The good news.... Plenty of power (overheating problem resolved)...the car is still in one piece (the wall jumped in my way only once) and I pulled out an 11th and 21st finish.
Bad news: good luck getting the thing to turn or to stop turning....the car was all over the track.
I figured that something is still wrong. I measured everything again (mic'ed the springs).... it turns out that in re-assembling the car I put the big spring on the RR and the little spring in the LR.
I switched the springs and reset the ride heights and moved a few things back in the car. Now I get the following at baseline:
Total car (fully loaded): 3,140 (within 20# of the track scales).
I figure this is my 'early night' setting.
Now I put in a couple rounds of wedge in the LR (along with dropping the rear pressures 1/2#)and the cross goes up to 52.1% for my 'slick' setting.
This sounds close to what everyone here says is good. I can't wait to see if the car behaves better this weekend.
Track is 3/10 medium banked.
Give me your guidance. Minimum weight required is 3,100. Should I add some weight to bring up the rear %? I am getting a lot of tire spin but I attribute a lot of that to inexperience in my 'applicator' within my right shoe. Will the extra weight offset this problem until I can control my right foot or should I leave the weight off the car?
Thanks for your continued help and support,
