8.25 on 139 lows is fine. If you wanna get the lows, get the lows. Especially if you're getting stage 11's which I assume, the forged ones are 53mm in height now so even then theyre alot higher than lows. If you get the regular ones, its like standing on the top of empire state building vs the ground below it.
If you ride loose trucks or like to turn at all, dont get the lows.
