I'm thinking of getting a set of these to hunt down my 10 second slip. 17x4.5 in the front and 15x8 in the rear with a 28"x9" bias ply slick. Should be enough to hold 630hp?
My question is this. I'm running a 27.6" tall tire right now and ran through the traps @130.5 mph on my street tune. My car is a 3.31 gear and I'm not running the boss intake...It's a novi 2200 car with a wastegate setup so I have more TQ.. Will going to a 28" tall tire hurt me or will the .4" difference not really be noticeable? I'm thinking with my 100 octane race tune and the lighter wheel combo I might see 3-5 more mph in the 1/4 and I'm banking the slightly taller tire will help.
Thoughts?
a full slick is going to grow a bit on you too. if your looking to pull a little gear out, then yes, if not, then go with a 27", this is where things get tricky and trial and error come into play. lol
