SFC: Different design patterns, why?

**MrMasterCraft** · 12-25-2009, 06:20 PM

Ok, so I've decided to go ahead and do the suspension before the rear, and as I was surfing jegs and summit today, I saw some different SFCs. The BMRs were just one long rod lookin' deal and the SLP's were more of a web-shaped design if you will. I understand that the whole point of these is to stiffen up the "subframe" and prevent twisting of the chassis under heavy torque load but does anybody have any pictures of SFCs installed on their cars, bolt-ins or weld-ins? I'd like to see some SLP SFCs if anybody has any installed on their cars, so I could see the welded location points on them, if that makes any sense. I'm getting pretty serious about this build, and am trying to get as in-depth as possible to ensure making the correct purchase, and right install. Thanks for any help in advance fellas

I can't comment on the SLP design -- I installed 2 point UMI bolt ins on our car. They are of the tubular design and fit perfectly. By the weight of the pieces, I would have to say that they are quite rigid. Forgive the crappy cell phone pics -- I forgot my camera on the day I installed them:

Right on, why did you go bolt-in over welded-in, just curious?

You can always go in later and weld them in!!!

Ease of install. Plus, as noted, I can weld them at any time.

Gotcha... now that I see the pictures I can contemplate and decifer the rest. Thanks fellas!!

Are you considering the 2 point or 3 point?

**LS2GTO** · 12-26-2009, 02:54 PM

I'm looking into SFC myself and wonder which would work best for my application which would be mostly aggressive street driving.

2 point or 3 point sfc's. Chromoly 3 point vs. boxed 2 point? Been checking out UMI and BMR stuff cause I also like to one day install either brand front K member. SLP doesn't make a K member however I'd would like to hear some info on those sfc as well.

take a look at ky speed they are sponsors here and have the best prices and if not they will match it. i like umi stuff the best im not a fan of slp stuff. i have umi 3 point bolt on's and love them they sit nice and close to the bottom of the car

01 T/A, what style of driving do you do that convince you to go with a 3 point vs. others?

**00z28bubba** · 12-30-2009, 04:03 PM

3 pt for playing should be the consensus. more support points in the correct spots will always be stronger than fewer points. the only reason i can see to not get 3 pts is if you absolutely cannot afford it. and in that case you shouldnt be playing. im not saying 2 pts dont work but there is realy no mild play because these cars have a lot of torque. the torque wont take it easy on your car unless you dont play. my opinion, take as much info as you can get and make your decision.

i got the 3 point for i drag race about 2 times a year but you only need the 2 points for that but i do what to try and autocross some and any thing i can do to keep the car as solid as i can. over kill is a safe way to be and thats way i got the 3 points.

The three point really limit your exhaust options and are heavier if that makes any difference to you.......

Depends on the duals you run, if you get that asphalt scraping texas speed setup probably. My custom 3" dual exhaust was unaffected

I'm sticking with factory exhaust configuration. How much of a weight difference are we talking about? A 3 point in chromoly would probably be the best choice in terms of weight and rigidity.

My KB 3 Point SFC's was ok as far as weight, i thought it would be alot heavier but i can lift both of the SFC's with one hand and maybe even with one finger. So i originally thought they would be very heavy but in my case it was the exact opposite they were very light. I didnt notice a huge difference with them as many people claim with SFC's. Then again my car is a hard top so maybe it didnt have as much flex, dont know. I know my 93Z hard top, after intalling a 2 point made a big difference but that could be because it was a much older car with many miles on the body. Either way i would recommend it because i felt a slight difference. Cant wait to put on some Sway bars.

gotta say i like my UMI SFC. I got the two point bolt in. Definatly considering welding them in though. The freakin cold has caused the metal to shrink and now the front part of the SFC's have gotton loose and are bangn like no tomorrow. Only when i accelarate. freakin wisconsin weather. Once i get my mig gun running im zapin those dang things in place. Other than that i love my SFC.
