I run both. My T-4 I leave the way its setup from the instructions. Yes its set up for off-road, but its close. You might play with the shocks a lil but it wont be much. I run mine MOD with a Mccallister Retro Ford body. Looks cool, has a high rear spolier built in. Works for me. I ran a 9X1 with a 87/16 last weekend at Jacksonville IL and qual 8th in the A with it. Mind you that was against Nitro and Wedge cars. So thats no to bad.
The B-4 I have greens on front and rear. I run a EDM body with no mounts. I use the front shock tower to hold the nose down. The rear shock tower is the rear body mount. That way I can go back to off-road if I need to without changing a bunch of stuff. I ran a 84/22 stock I think... Not sure.
