Question for the wheel guys. Right now I'm using 1.25" billet adapters for my rears wheels (18" Z06's). I hated the way the wheels looked tucked in. Anyways I'm about to put Hoosier Quicktime Pros on some stock 16" wheels that I will be using only at the track. This will be the first time I use drag tires. My question is: Is it safe to run sticky tires with the adapters on or do I need to take the adapters off when I put the drag wheels on at the track. Of course I ask 'cause it will be a PITA taking everything off and put it back on at the end of the night but I also don't want to see my wheel pass me at 100mph as I hit the wall. Advice please.

IMO, I don't see any reason why you should need to take them off.

how much power to the ground, what size drag tire and any mods done to improve launch?

Unless you have 5/8" wheel studs, spacers are not a good idea for drag racing. You take the load away from the flange of the axle which is designed to carry that load, and then you transmit it through the studs.

Even worse is running them with a spool, especially on the street!

I have full bolt-on's. LCA's, subframe's, built tranny w/ 3500 stall, stock TA w/poly bushing. The tire will be 26x9.5-16 almost full slicks, they do have a couple of grooves down the center.

I'm still on my 10 bolt and they're not spacers, they are bolted on just like a wheel then the actual wheel bolts onto them.

I am no expert at all, but I'd put your rearend as the weak link - not the bolted on spacers.
I see the type you have as an extension of the mounting hub so the wheel is just as secured as without - just my opinion.
12mm lugs/studs as factory still?
I think at your power level the axle or center section will break before you snap studs.
If It were a 500+ hp to the ground car, 10" or bigger slicks and 4000+ stall - I''d rethink it.

I realize the 10 bolt is weak, that's another concern. My concern right now is, is it safe to run drag tires with the adapter's still on or should I just take them off when I race?

In other words - the adapter should be strong enough to leave in place at your power level.
I thought my opinion was clear - but I took out the 10 bolt concern and reposted. You could contact the adapter manufacturer and ask them also.

Oh ok, I understand what you're saying^^^^. Is anybody out there actually running drag tires with these adapters. Someone post up.

If you are worried about it why risk it. Just take them off and then you wont have to worry about anything happening. Better to just be safe when you are going to be traveling at high speed.
