[arter]

I had my chamber set at -2.8 and it ate up the inside of my street tires in like 2000 miles. Currently dropped down to -2.2 or -2.3 and seems pretty good for both ( still some outside war on the track but acceptable for me).

Have adjustable ground control plates, but never bothered to change them at the track ( just another thing to play with and the cash prize for winning the HPDE event just didn't cover it).
