Thanks mate, it was very helpful!
The thing is, there is no (or i did not find it) 3 degree HRC block. and i can't believe that half a degree is so much difference.
I guess i have no other choice but to test ist
I think i'll get the 2.5 LRC first, as the track i race on actually is quite tight and the rear end is rock solid, and it does not feel right to loosen up the rear and still keeping the high toe.
And i know it should be faster with the mid car, but i could not drive it as consistent as the rear car. But for me it's fast enough and i can still keep up with some of the chaps on my track.
