Is it worth putting SFC's on a hard top?

Did you feel much of a difference after the install, daily driving or at the track? I am scheduled to have a set of BMR's installed next week and having second thoughts on the necessity of them rate now. ]

Thanks

Cool

You won't regret it The frame needs to be tied together for the best handling possible so everything can work in conjunction

The car feels pretty stiff as it is. I don't get any wheel hop really, except a little in second gear. I am running 315 drag radials and plan on doing BMR LCA's also at the same time. Any one else have some thoughts on this that have hard tops?

Should be the very first mod anyone does. Even before a cold air intake, headers, or cutout.

I have had a set of BMR's on my Formula for about 2yrs now. It does seem to tighten up the car & helps reduce squeeks & rattles that are common to a unibody car. Also very handy as a place you use a floor jack on since BMR's are very stout square tubing. Get them, you won't regret it.

Definetly worth it IMO. You can really feel a difference after you install them. And if you go to the track with sticky tires, it will help stop your car from flexing on the launch. I know a guy with about 450 RWH and he didn't have subframe connectors. After a year or so of frequent track use he had problems opening and closing his passenger door.

Even the "hard top" cars are just fiberglass roofs. The roof isn't the problem anyway, it is having a sheet metal floor pan as the main structural member. Yes, you WILL notice a difference w/ the subframe connectors, and it will save your car from being ruined by continual twisting. I've seen many, particularly 3rd gen, but some 4th gen cars twisted irrevocably by torque from their own engines & launching.... It even happens on old 60's cars that are unibody, i.e. Nova & first-gen F-bodies.

Get subframe connectors.

I guess my next question is boxed or tubular? I was thinking tubular to try and keep them as hidden as possible. Is there much difference between the two. I get enough **** about modding the car as it is, as soon as people see things welded in it's probably going to hit the fan. I think the Firehawk crowd is worse than the Corvette guys!

Get BMR's, either tubular or boxed. The boxed are stronger, but the tubular tuck up better out of the way....

I got the boxed, which hang down just enough that I actually like it, because it makes good strong lift/jack points without marring the underbelly.... consider that a plus to keeping your car in good shape

I agree with this statement.

I agree too.
If you don't want them visible, get tubular or DDs.

There is a substantial steel structure under plastic hardtop roof.

well then i guess i better get some too. getting tired of the squeaking.

however, are the bolt-on SFC's any better than the weld-in ones?

if not i think i will get the tubular bolt-ons, but want to know as much as possible first.

thanks
