i have the same question, but im planning on adding a kenne bell blower in a little while so is 4:10 too much gear for that set-up, i know guys are running centri's with 4:10's but the KB has some more low end.
You should get some DR's. I bought dunlop SP8000's 315/35/17 at first thinking those would get me some good traction, They were better but by no means sufficient. I was gettting sideways in third. I got some Nitto DR's and now I boil'em in first, squel'em in second and chirp third. They helped me out a lot.
