So I've read a few articles on it, I've watched the (always awesome) Jason Fenske on EE explain it on youtube. But I am left with a few questions that people smarter, and with more experience, than me could hopefully answer.
Stock Austins leave us with 0mm scrub radius. I have stock suspension right now. I have been tracking with using 235/40R18s on an 18x8 rim w/ et35. So, using online scrub calculators, they say that my wheel set-up increases my scrub radius to a positive 13mm. I think I feel an increase in steering effort with the track wheels on (vs my winter tires on Ausitns) but it may just be the stickier tires...but again, I don't know enough...so
1) How will a positive 13mm effect the car's handling?
2) Think it will effect turn in feel notably?
3) Is 0mm scrub radius the ultimate goal for track driving set-ups?
4) How can I determine how 034 camber plates (-1.5ish...its still my DD...not going to full adjustable set-ups) would effect my scrub radius with the track wheels?
5) I have had lots of lowered cars, but never thought about scrub before. If I lower it modestly (.75-1" max) is there a way to figure out how much negative scrub that will add?
And finally (feel free to skip all the above questions); am I just overthinking the whole dang thing for a DD that gets ~4-6 track events per year?
