Smaller wheels, more traction?

I backed off the dampening to fully soft andf raised the hight on the front
the car launches alot better now
still spins a hell of alot but hardly hops!
seconds are smooth

i had 215/40-17s on my car the rolling diametre is 609cms
factory integra 14s have 195/60-14 wich is 590cms
with the 17s i had increased my top speed and reduced my acceleration and had a lot more traction!!!!
id rev it out smash it into 2nd and all it do was squeal,
i put my 15s on 195/55-15 = 596cm diam, i can start a burn out in 1st and change into 3rd and still keep spinning!
i can feel the diference acceleration wise its hell of a lot quiker!!
my girls integra (stock gsi auto) could beat me when i had 17s on and ive moded my car and its manual.

if go to smaller diameter you will have even less traction!!!

and ive confirmed it all at the drags too. stock car run 15.6 @ 89mph
last week with 17s and 20hp more 15.8 @ 88mph

lost speed at all the traps!!
some more than 6ks!!
