Help me reach my goal of 12.9

[LX XLR8R]

get a small set of drag radials..i would not suggest slicks..cuz if you get slcisk i think you will go the same time or slower(your mph shows you are not making insane amount of power that would spin them effectianly)
on our N20 car we go 11.5x@116 on 26" slicks
off N20 we go 13.0 on slciks and radials..no differnce..both MPH ranging from 102-104..and we are running 3.73's..with those 3.55 and 26" slicks i really think you will be loosing out

the simple combo we are running is heads,cam, exhaust and gears..stock intake/tb/massair/jectors and a 150 bang for when 13.0 isnt cutting it

if you were running 13.2@108 then i say yea put on a slick and see some 12.50's

so what i suggest is 4.10s, slicks and a good tuning
