I've just started doing my own scratch tunes.
I've tuned the 512 BB on Apricot Hill, really happy with how I've managed to balance it, including corner entry / exit, LSD, and almost perfect weight dist through a corner.
Then I've taken her to Grand Valley Speedway, and I can't break for the first righthand hairpin after the straight without skidding off the road almost immediately upon hitting the breaks.
It seemed the car was being overloaded on the front end, and then overtaken by the back end as my brake balance was higher on the fronts.
I pushed the weight slightly back which improved it, but this ruins the lovely balance I had on the limit mid corner, and this makes it a lot harder to pithily catch a slide.
I increased the rear toe in, which also helped, but this results in indersteer exiting the many long tightish bends on this track, another compromise I don't want to make.
The other thing I did was increased LSD decel - but this is now upto 32 so don't really want to take too much higher.
Can anyone recommend anything I could try that would mean I dont have to make the above compromises?
I have fairly soft springs, midish dampers (higher setting compression front and extension rear than ext front and comp rear to give grip on accel), and mid to high arb's - higher setting on the front.
Any help much appreciated!
