bolt in are not NHRA legal, i have a S&W 8 pt. i had to modify it a little because i'm a tall guy and i wanted it hidden better. chromemoly is the way to go but unfortantly, you have to tig weld it.

Bolt-in roll bars are NHRA legal.

NHRA book says "ALL cars with OEM frame MUST have roll cage WELDED to frame." and i think you have to have at least 6 point for NHRA

Wrong on both accounts.

5 OR 6 POINT ROLLBAR CONSTRUCTION (NHRA LEGAL) (Required beginning at 11.49 with a closed car/truck, 13.49 with a convertible)

NHRA Rulebook, General Regulations 4:10 ROLL BARS:
All roll bars must be within 6" of the rear, or side, of the driver's head, extend in height at least 3" above the driver's helmet with driver in normal driving position and be at least as wide as the driver's shoulders or within 1" of the driver's door. Roll bar must be adequately supported or cross-braced to prevent forward or lateral collapse. Rear braces must be of the same diameter and wall thickness as the roll bar and intersect the roll bar at a point not more than 5" from the top of the roll bar. Crossbar and rear braces must be welded to main hoop. Side-bar must be included on driver's side and must pass the driver at a point midway between the shoulder and elbow. Swing-out sidebar permitted. All roll bars must have in their construction a cross bar for seat bracing and as the shoulder harness attachment point. Cross bar must be installed no more than 4" below, and not above, the driver's shoulders or to the side bar. All vehicles with OEM frame must have roll bar welded or bolted to frame; installation of frame connectors on unibody cars does not constitute a frame; therefore it is not necessary to have the roll bar attached to the frame. Unibody cars with stock floor and firewall (wheeltubs permitted) may attach roll bar with 6-inch x 6-inch x 0.125-inch (1/8") steel plates on top and bottom of floor bolted together with at least four 3/8-inch (0.375") diameter bolts and nuts, or weld main hoop to rocker sill area with 0.125-inch (1/8") reinforcing plates, with plates welded completely. All 4130 chromoly tube welding must be done by approved TIG heliarc process; mild steel welding must be done by approved MIG wire feed or approved TIG heliarc process. Welding must be free of slag and porosity. Any grinding of welds prohibited. See illustration. Roll bar must be padded anywhere drivers helmet may contact it while in driving position. Adequate padding must have minimum 1/4-inch compression or meet S.F.I. Spec 45.1. All cars running 180-mph or faster, S.F.I. Spec 45.1 mandatory

Per the NHRA rules:

The roll bar is accepted in vehicles running as quick as 10.00 second e.t., provided the stock firewall and floorboard is intact, other than for installation of wheel tub.

Bolting the base plates is legal. Bolting the bars together is not. The rear bars at least need to be welded to the hoop.

Where are you at? Our 6pt CM installed starts at 650.00

When your looking for something safety wise, its not recommended to always go the cheaper route. If you do find one thats cheap it may not fit really good. Also, if you arn't the best of welders, I would recommend getting it all put in the car and taking it to a someone to weld it all up.

if your in the pa/md/va area, go to PAF in baltimore, they did mine it came out perfect
every car they do if custom and not a premade bar. the 6pt is good to 9.99

Yeah I agree, I would honestly get it custom. By the time you figure in freight and the headaches you'll get from not fitting just right you will thank yourself. Ive never seen a prefabbed kit fit like it should, the main hoop is always too close to the drivers head.

id have to agree on getting it custom made for sure. PAF in baltimore did mine and everything came out perfect

The 650.00 does not include the swingouts. We can put them in. It may be inexpensive at 650.00 but is custom and done to perfection.
