Bolt-on vs weld-in subframe connectors

Is is going to make a big difference welding on subframe connectors over bolting then on if you have 850 fwhp in a 68 camaro with complete caltrac setup and good shocks with solid body mounts?

I use these bolt-ins on three 69's:

Re: bolt on vs weld in subframe connectors

Welding them in will definately be better than bolting them in when having 850 hp under the hood. And, usually, the bolt in type tends to hang down lower and is more noticeable. At least the old school stuff did back in the day.

Not hijacking just wondering if they require floor mods? Hate to cut a new one piece.

Buy a set of Hotchkis subframe connectors, they hug the floor board.

fwhp = flywheel horsepower. Still crazy ponies at the wheels

Re: Bolt-on vs weld-in subframe connectors

I went with the CE bolt ins and am happy with how they look(not hanging down). Heard nothing but good things with the Hotchkis SFC..

68 Camaro SS... getting there!!

Re: Bolt-on vs weld-in subframe connectors

I run the bolt in CE's like in the link. I have thought about welding them in but I have a nightmare of a time getting one of the j-nut bolts started every time. I have to wiggle things around and hold my mouth just right to get it started. I am afraid if I welded the connector in place I'd never get it started.

Don't the Hotchkis require cutting the floorboard?

I am about 700 fwhp.

Re: Bolt-on vs weld-in subframe connectors

No, the Hotchkis SFC do not require any modification to the floor board. They are bolt in, but I'm going to weld mine in when my car comes back from the paint shop.

Eric – The inexpensive bolt-in connectors are great for drag racing if your car is stock height or higher…and you’re only driving your car in a straight line. If your car is lowered and you’ll be driving it on the street (or you’re drag racing it and you improved support), you’re going to be much happier with our contoured subframe connectors that weld-in without cutting the floor pan. Talk to anyone who has switched from one set to the other. They do make a difference…and with 850hp your Camaro is going to need all the help it can get.
