Re: Roll cage/ mini tub

The only way to really find out how much is too much in regards to footprint is to do some back-to-back testing with different size tires imo. Such a test would require having 2 or more sets of tires mounted and ready at the track so the conditions will be similar. In such testing eliminating variables (or reducing them as much as possible) is pertinent to having an accurate test.

My bad. I forgot that I cut the upper wheel well molding off back in '69.
Those tires fit in there realllllly nice. Back space is 5.5" on these wheels.




These are last season's Hoosier's. Same size. You can see the cutout.


Tight, very tight.




Mid to low 10's huh? Are you going to run a power adder? Please don't, that's cheating.
Now here's a tid bit for you; First gen Camaro's are NHRA LEGAL DOWN TO 10 FLAT WITH A 5 POINT ROLL BAR Any quicker, into the 9's, you'll need a NHRA license plus a whole bunch of other stuff.
Do your roll bar right and it'll work well for cruise night too.

Here's from 2years ago. Notice that the rear bars are installed but nearly invisible. They're called rear-seat-savers from Art Morrison.


Here's the rear shelf. Now THIS was,,,,,, tricky.


All buttoned up. Even the side bar is removable. The passenger side doesn't need one. Our SO's like that.

Mid to low 10's. Maybe not this motor. I don't think I'll ever be below that in my life time. I think your 69 may have a little more tire room than my 67. If the rear cross bar is made to be removable the car won't cert correct?

John I missed that your car is a 67. I'm not sure how different our cars are in wheel well room. Hopefully guys with both cars will jump in here.
The rear crossbar has to be welded solid to the hoop. Only the occupant door bars can come off. Also a TIG or MIG must be used (depending) and the welds can NOT be ground.

Thanks Fred. I'm starting to wonder what I would really gain going from a 9" rim to a 10". Geesh guys run in the 10's on 8's with a 275. 10's do look better!

Re: Roll cage/ mini tub

John, Michael, in post #16 said it best. Wheel size is just one of many factors that affect each other. That's tuning for you. And I use both 8" and 10. Can't tell the difference but that's just me.
