roll bar vs cage
roll bar vs cage do you think i should go with a 6 point roll bar from wolfe or with a 10 point cage thru spohn (basically the same as the six point but with a halo, A-pillar downbars and additional contact point in the rear) neither requires modification to the dash or firewall, but would a 10 point be overkill??
my car will be a road racer that sees limited street duty (75 and sunny or nicer ONLY), with tons of power to play with. i like the idea of a cage not only because it keeps the roof off your head if you put the car on its top (definatly nice if you have a t-top car like i do), but also for the structural stability - i'll be running a moderate H/C combo on a 427 so containing the torque is a contributing factor - but if the added points really wont help all that much, i'll be happy to ditch the extra weight.

Do your homework.
At some point in time, you might decide to compete in a series in that car. It would be a shame to have to ditch all the time and effort spent on either cage only to find out it does meet specs for a series.
Having said that, neither the Wolfe or Spohn cage/bars meet anything close to road racing specs.
I know Wolfe only uses ERW tubing and suspect Spohn does the same. Almost all classes of road racing I'm familiar with requires DOM tubing.
Also, a bolt in cage is just about next to worthless as it bolts in through the floor pan.
This practice doesn't give you a solid foundation to build off of, it intrudes into the passenger compartment quite a bit, causing things like heads, arm and legs better contact points.
And consequently, doesn't add a tremendous amount of chassis rigidity,

Notice the base plates welded to significant structural points (where multiple seams come together).
And amazingly enough, the inside cage demensions are almost identical between 3rd and 4th gens. I was very surprised ...

that's great info mitchntx. My question though, I guess kinda related, if you put a cage in the car since it adds so much rigidity to the car, do you still need subframe connectors?
I went with a 6 point from wolfe cause of ease of instalution and it meets the track standards. Im a street/track car so for me I think it was the best choice....plus I got a kick *** deal on mine. If one day I decide to go real BIG well then I take it out...it wont be hard.

Spohn gets there roll bars from S&W race cars, its not on spohns site but there is a DOM 10 point that S&W makes its 400 bucks compared to the listed 200, and really the S&W cages need to be bent and notched, when I got my 8 point bar the only bar that was bent was the main hoop and we even bent that a little harder to match up the the cars better, I would think that halo would be bent in a 10 point kit as well but its a lot of work bending and notching a cage in a car, it took me and a friend 2 days to put mine in with my car allready gutted out and thats all he does is put roll bars in. heres a couple of pics of a S&W 8 point kit

You would need to get a set of rules for the class you are looking at competing in and check.
For NASA and CMC,

1.500” x 0.120” Chrome-moly / Seamless mild steel (DOM)
1.750” x 0.095” Chrome-moly / Seamless mild steel (DOM)
1.750” x 0.120” ERW* (No issuance of log books for cars with ERW cages 04/30/03)
*Note- Specifications listed for reference for inspection of grandfathered vehicles.
3001 - 4000 lbs.
1.750” x .120” Chrome-moly / Seamless mild steel (DOM)
No ERW allowed.
