It really depends on what your looking for and what you want to spend. I run Nittos on the back, because regular radials on my car is scary. Even when I had the stock turbo, anything under 40mph and it would just light them up. The nittos are also pretty good in the rain and last a lot longer than the BFG Drag Radials.
I'm running Nitto 275/50/15s on back and BFG radial TA 215/60/15s on front.
