Was the kit rubbing due to the drop spacer? Even though it shouldn't.
By "drop spacers", do you mean blocks? I don't think they played a role in the rubbing issue. They might've prevented the ability to move the bottom bracket just a little further farther forward, thus avoiding the rubbing issue, but it's hard to tell if the axle or something else might've prevented that as well even if the blocks weren't there.
how much did the kit cost? i just put 3" blocks in. haven't drove the truck yet cause i'm still doing the drop coils this weekend but if i have problems bottoming out i might look into this if its cheaper than getting qa1's
Although I know QA1's are the commonly accepted *solution* for bottoming-out among Tacoma owners, it's like using a screw driver as a hammer. Sure, it might work, but it's not a good idea and isn't using the tools what they were intended for.
If you're concerned about performance at all, you should be concerned about your vehicle's ability to keep the tires in contact with the road. Shocks and springs in combination attempt to do that. If you by shocks and then remove their ability to actually absorb shock and control the springs (i.e., dial-up the QA1's until they're stiff as a rock), then you've just created one problem to solve another. Sure, your truck might not bottom-out, but your suspension is going to be extremely harsh and your tires will "bounce" over bumps instead of absorb them because you took all the "absorption" away!
The Roadmaster kit is more expensive than the QA1's, but TacomaWorld member jmarquez808 has QA1's and the Roadmaster kit and he's been able to dial-down his QA1's to sane levels as a result. (

Don't get me wrong, QA1's are quality shocks, but they're shocks and should be used as such.
