Im just looking for info, is there any variance in strength or rigidity?

Welded SFC's are going to be alot stronger, and less likely to move on you. We weld in all of the sub-frames we put on any car. I can get you set up with some BMR tubular sub-frames. They are quality pieces. Here's a link to our online catalog:

Weld them, even if you get bolt in SFC, I bolted mine in and plan to have them welded, but you really have to watch the bolts and get them torqued down otherwise they WILL shift.

Welded both of my cars, and advise the same, make sure the suspension is loaded for the welding (roll-on lift).

I have the 3pt bolt in sfc and had it on fir a year & then decided to have them welded in and there was a noticeable difference. Just weld them in.

I have weld-ins on my car. The nice thing about bolt-ons is that they're easy to remove if you decide you want to do so.

I went bolt on, but I plan to weld them in. I wasn't sure I would like the effect, but I can tell you that as SOON as I even sat in the car after having them installed, I knew I would never take them off. That was almost four years ago now and I still haven't had them welded in, but I would not drive one of these cars without them.

Like many have mentioned welding is always going to be the best option. However we have had good luck with our bolt in style and many cusomers purchase the bolt on SFC's with intentions to weld them at a later date... this is always a nice option to have. Our bolt in SFC's are the same as the weld in, same connectors just different bolt kits and brackets.

I posted a link below to show the styles of SFC's UMI has to offer. If you have any questions please feel free to ask.

lol... I just got bolt ons and can't tell a bit of difference. If you think those made a difference throw on some good shocks, you may want to have a pair of diapers on as well when you see the difference they make

HAHA... Thanks everyone for you opinions... Im taking in everything everyone says into mind. Ive gotta motor (never been dyno'd) but its pushin anywhere from 500-600 hp all natural aspiration power. I had weld ons on the old car but i totaled that one out when i got lost in the spin of doom. Thats another story though. I know that i will need sfc though, theres none on the roller body in getting ready. The old car with the SFCs would twist like crazy. Would 3pt SFC be a better idea?

Standard tubular SFC's with an anti-roll (rear adjustable sway bar) will take car of any twist your car may have during the launch. A cage wouldn't hurt either, depending on how fast the car is.

Dont mean to hijack but I need a set of SFC as well. What is the advantage of 3 point vs the box style vs tubular SFC? Do 3 point SFC cause any clerence problems for true duel or Y pipe exhaust setups?

mad_steve

iTrader: (2)

IMHO 3 point SFC's aren't necessary. A set of tubular BMR SFC's are plenty of support for these cars.
