currently i have around 400hp and i race at my local track 1/8.
will a 15' rim give me a faster time or a 18' rim?

trying to solve my problem of spinning every gear

was thinking of getting 15x8 rim with 255 rear mickey thompson street s/s

or

keeping 18 and going street s/s 275/45/18

over the two a 15 with more sidewall and lower psi
the back end barely dropped like it's too hard spring rate and/or compression damping
stock rear struts springs may work better
there is the drag zilvians thread for more set up ideas and info others run
