hmm, interesting that with tyreTry with more tyre pressure at the rear next time. It normally makes it easier.
Have you ever measured the power from the engine on a dyno?
P.S. Do you think it is loud enoght?
my tire is little empty because rear end is softer then
Unfortunately I did not measure the power, I have no where here in Croatia to do that
it is too loud! too too loud! this year i will be driving only on serial exhaust, enought with noise, 5 years of loudness is enought for my ears
