This is just me, but some people are all motor phanatics, I'm a street freek. I say keep it street legal. I use 15 inch G-force. I ran a 12.4 with a 1.98 60 foot and I know I can do better. As far as axels go, I've broken my driver side 3 times on the drag radials. So in my oppinion Drag Radials are more efective then baby or small slicks. If you got the power that you need slicks then cool use real slicks and after market axels. I put about 300 to the ground. If you do get the the G-force, make sure you break them in properly. It says to do a burn out for like a full minite then let them sit for 24 hours. But dont quote me, get the instructions. I didn't break mine in correctly and I could tell a big difrence
